WEBVTT - The Tire Head 0:00:00.080 --> 0:00:02.120 I'm going to take my shoes off. Everybody. Sorry, it's 0:00:02.120 --> 0:00:04.120 been a long day and the shoes are coming off. 0:00:04.240 --> 0:00:07.600 So it's like when mister Rogers takes his jacket off. 0:00:07.720 --> 0:00:09.799 It's like, my shoes come off. It's time to start. 0:00:10.600 --> 0:00:12.320 Happy to be in the booth for once. 0:00:12.800 --> 0:00:15.920 Tony Michael, thanks for all the great clips you sent, 0:00:16.000 --> 0:00:18.239 all the information you sent me in advance of this 0:00:18.480 --> 0:00:22.440 Tire Ahead recording. But it just occurred to me, I 0:00:22.480 --> 0:00:26.079 can't remember the last time I changed my tires on 0:00:26.160 --> 0:00:30.120 my car, and everything seems fine, which got me thinking 0:00:30.600 --> 0:00:33.400 of all this endless tire talk and more tire talk 0:00:33.440 --> 0:00:36.159 that we're going to have. Why does an f one 0:00:36.200 --> 0:00:40.240 and all their data and technological advancement just make tires 0:00:40.280 --> 0:00:43.640 that hold up better that would be better for the 0:00:43.760 --> 0:00:44.840 environment as well. 0:00:45.280 --> 0:00:45.559 Do that? 0:00:46.320 --> 0:00:48.520 Okay, so I think, well, I think a lot of things. 0:00:48.520 --> 0:00:52.000 But first, just from a safety perspective, you might want 0:00:52.040 --> 0:00:54.920 to take your car in and have those tires inspected. 0:00:56.120 --> 0:00:59.000 For My Heart podcast one on one Studios and Sports 0:00:59.000 --> 0:01:14.720 Illustrated Studios, this is choosing sides, yes one wow, Wow, Tony. Respectfully, 0:01:14.720 --> 0:01:16.720 I feel like I already know everything there is to 0:01:16.720 --> 0:01:17.920 know about tires. 0:01:17.680 --> 0:01:19.520 Respectfully, I beg to differ. 0:01:19.920 --> 0:01:21.880 Hey Matt, Hey, how's it going? 0:01:22.360 --> 0:01:24.720 You know, not too bad? And to convince you otherwise, 0:01:24.760 --> 0:01:27.800 we have invited to the show some true tire heads. 0:01:28.160 --> 0:01:32.479 Matt welcome. Who are you for our listeners? Who is 0:01:32.600 --> 0:01:33.760 who is Matt? 0:01:34.600 --> 0:01:35.800 I am Matt Trumpets. 0:01:35.800 --> 0:01:39.199 I'm co host of Mister Apex podcast, host of tech 0:01:39.240 --> 0:01:43.080 Time on Mister Apex, and I am a professional trumpet 0:01:43.080 --> 0:01:47.960 player who somehow managed to find himself on a podcast 0:01:48.040 --> 0:01:51.080 about Formula one with a bunch of people from England. 0:01:51.560 --> 0:01:53.160 So that's who I am. 0:01:53.320 --> 0:01:54.800 And that is Matt playing in the background. 0:01:54.800 --> 0:02:03.120 By the way, well it's actually quite lovely. 0:02:05.040 --> 0:02:08.359 Any overlap between the trumpet worlds and the Formula one 0:02:08.360 --> 0:02:10.840 world or are they just two very different worlds? 0:02:11.120 --> 0:02:14.880 No colliding needed, There's loads of colliding needed because as 0:02:14.919 --> 0:02:18.360 a professional musician, as a trumpet player, it performance is 0:02:18.480 --> 0:02:21.120 what I'm about. And so anytime you look at something 0:02:21.160 --> 0:02:24.600 like Formula one, you look at the job the drivers do, 0:02:24.720 --> 0:02:26.839 you look at the job the engineers do, and they're 0:02:26.880 --> 0:02:31.200 all performing under an unbelievable amount of stress at the 0:02:31.320 --> 0:02:34.360 very very highest level, and in particular the drivers, and 0:02:34.400 --> 0:02:36.760 I know what you want to talk about I know 0:02:36.800 --> 0:02:37.840 you want to talk about tires. 0:02:37.880 --> 0:02:38.520 We will get to that. 0:02:38.760 --> 0:02:41.720 But when you look at the drivers, yeah, and you 0:02:41.760 --> 0:02:44.960 look at something like their lap times in a race, 0:02:45.639 --> 0:02:48.600 and they can be consistent within a couple of tents, 0:02:48.840 --> 0:02:51.680 lap after lap after lap, and then their engineers will 0:02:51.680 --> 0:02:53.880 say things like we need you to do something entirely 0:02:53.960 --> 0:02:56.800 differently but not lose any time, and they'll be within 0:02:56.880 --> 0:03:00.360 a tenth of what they were doing. The consistency they 0:03:00.360 --> 0:03:04.119 bring at that level while they're raising other people, it's 0:03:04.160 --> 0:03:06.440 just it's astonishing to me. It was really one of 0:03:06.440 --> 0:03:08.680 the first things that sort of drew me into the 0:03:08.760 --> 0:03:12.720 sport before I even knew anything about tires or Formula one. 0:03:18.600 --> 0:03:20.760 Okay, so what's so special about the F one tires? 0:03:20.760 --> 0:03:25.639 First of all, what are F one tires? Okay? 0:03:25.680 --> 0:03:28.360 So first of all, let's start with this. Tires on 0:03:28.440 --> 0:03:32.560 their own are unbelievably interesting, and the thing that is 0:03:32.639 --> 0:03:37.320 most interesting about them, kind of like dark matter, is 0:03:37.560 --> 0:03:42.200 no one can entirely explain exactly one hundred percent how 0:03:42.280 --> 0:03:44.640 they work. I mean, the gases have gotten a lot better, 0:03:44.680 --> 0:03:46.960 there are models out there you can use, but at 0:03:46.960 --> 0:03:50.280 the end of the day, it's this freakish combination of 0:03:50.320 --> 0:03:53.200 the kind of material and the different sorts of forces 0:03:53.520 --> 0:03:57.160 that cause grip to happen, and it just it's too complicated. 0:03:57.280 --> 0:03:59.920 No one can model it perfectly, no one understands it 0:04:00.080 --> 0:04:04.200 all the way, and it is the single biggest driver 0:04:04.360 --> 0:04:10.440 of performance differences. If you get your tires right, you're 0:04:10.480 --> 0:04:15.080 talking multiple seconds a lap. If you're an arrow guy 0:04:15.200 --> 0:04:18.080 and you bring an amazing development, that might be worth 0:04:18.120 --> 0:04:20.040 a tenth of a lap, But if your tires aren't 0:04:20.040 --> 0:04:22.360 in the window, that could be seconds a lap that 0:04:22.440 --> 0:04:26.240 you lose. So their single most important driver performance. No 0:04:26.279 --> 0:04:29.640 one understands them. And now they're the same for all 0:04:29.680 --> 0:04:31.880 the teams. All the teams have to try and get 0:04:31.880 --> 0:04:33.960 their heads around it and get it right or get 0:04:33.960 --> 0:04:36.719 it wrong. All your car design, everything is aimed at 0:04:37.640 --> 0:04:41.400 ringing the absolute best out of those tires, and it's 0:04:41.560 --> 0:04:44.040 really hard to do because getting back to point A, 0:04:44.600 --> 0:04:48.520 no one really entirely understands them, even at is zero level. 0:04:49.560 --> 0:04:52.480 Tires are complicated, and the more you know, the more 0:04:52.520 --> 0:04:54.480 you can enjoy watching the racing. 0:04:55.720 --> 0:04:59.360 Did you also know that some drivers are actually incredibly 0:04:59.400 --> 0:05:02.120 good quote unquote managing that tires? 0:05:02.400 --> 0:05:05.039 I don't what is that how do you manage a tire? 0:05:05.279 --> 0:05:09.200 You get back in there, let's go roll. Oh see, 0:05:09.240 --> 0:05:09.760 I love this. 0:05:09.839 --> 0:05:12.240 You're going to ask me about tire management, thinking you're 0:05:12.279 --> 0:05:15.160 going to get an easy, simple answer, and in fact 0:05:15.320 --> 0:05:18.720 you've just unlocked the most complicated. 0:05:18.000 --> 0:05:19.560 Aspect of tires. 0:05:20.600 --> 0:05:23.760 But I will try and keep it fairly straightforward and simple. 0:05:24.400 --> 0:05:29.479 So whenever you drive in a straight line, you're putting 0:05:29.520 --> 0:05:32.280 stress on your tires. If you're stepping on the gas, 0:05:32.360 --> 0:05:34.920 you're putting stress on the tires. And what is called 0:05:35.000 --> 0:05:39.680 a longitudinal direction basically the same direction you're driving, and 0:05:39.800 --> 0:05:43.800 then when you turn, you're adding a lateral component to that. 0:05:44.400 --> 0:05:46.799 And if you think about a tire having a grip 0:05:46.880 --> 0:05:50.240 level of one hundred for one hundred percent, you have 0:05:50.279 --> 0:05:52.520 to balance between the two, so you could be thirty 0:05:52.520 --> 0:05:57.720 percent accelerating seventy percent turning or vice versa. But when 0:05:57.800 --> 0:06:01.040 you do that, you're adding energy to the tires and 0:06:01.080 --> 0:06:05.040 that makes them get hotter. And the thing with tires 0:06:05.080 --> 0:06:07.960 is they're constructed basically in two pieces. There's the tread, 0:06:08.240 --> 0:06:10.640 the bed on top that touches the ground, and then 0:06:10.680 --> 0:06:14.560 there's the carcass, the bit underneath that actually keeps everything 0:06:14.640 --> 0:06:17.800 together and makes it work. And what you want is 0:06:17.880 --> 0:06:20.240 for the carcass and the tread to be of a 0:06:20.400 --> 0:06:24.640 similar temperature. And as that carcass warms up, it gets 0:06:24.640 --> 0:06:27.839 more flexible, you get more grip out of it. And 0:06:27.920 --> 0:06:30.160 so when you go into your turn, whether you're breaking 0:06:30.320 --> 0:06:35.200 or accelerating, and you're putting that energy in the tire itself, 0:06:36.120 --> 0:06:39.440 it actually isn't pointed quite the same way as the car, 0:06:39.520 --> 0:06:43.440 and that's called the slip angle. And the bigger the 0:06:43.480 --> 0:06:46.359 slip angle, the more energy goes into the tire. And 0:06:46.440 --> 0:06:48.839 if you make the surface of the tire too hot, 0:06:49.480 --> 0:06:52.920 you start to have problems with it. So you get 0:06:53.040 --> 0:06:56.480 things like graining, which you probably have heard people talk about, 0:06:56.480 --> 0:06:58.720 where you get this little ripple pattern. It's like having 0:06:58.760 --> 0:07:01.800 little marbles of rubber on the tire. And so if 0:07:01.800 --> 0:07:04.880 you overheat the tire when the carcass is too cold, 0:07:05.279 --> 0:07:08.839 you get graining and suddenly your tire won't go as fast. 0:07:08.920 --> 0:07:11.560 A great example of this was in the Las Vegas race. 0:07:11.600 --> 0:07:14.520 You had two drivers same team. You had Auckun and Ghasly, 0:07:15.240 --> 0:07:18.600 and Ghasly was having trouble managing his tires. He got 0:07:18.640 --> 0:07:21.040 graining and eventually fell all the way out of the 0:07:21.080 --> 0:07:23.680 top ten, and it was little things like he was 0:07:23.760 --> 0:07:25.800 going into corners in different gears. 0:07:26.280 --> 0:07:26.920 I don't get it. 0:07:27.760 --> 0:07:30.520 I understand. I kind of have so much regulation I 0:07:30.560 --> 0:07:31.280 was I boy. 0:07:31.600 --> 0:07:33.600 So when I talk about the drivers and their ability 0:07:33.640 --> 0:07:37.240 to manage things, it's being told things like, Okay, we 0:07:37.320 --> 0:07:39.240 need you to use a different gear, we need you 0:07:39.320 --> 0:07:42.240 to lift and coasts, we need you to manage in 0:07:42.280 --> 0:07:45.440 this corner. And they're not talking about a lot. They're 0:07:45.440 --> 0:07:49.280 talking about tens, hundreds, thousands of a percent. But they 0:07:49.280 --> 0:07:52.760 can make literally the difference between finishing fourth or fifth 0:07:53.000 --> 0:07:56.120 and finishing twelfth if you can do it or if 0:07:56.160 --> 0:07:56.600 you can't. 0:07:56.840 --> 0:08:02.440 I'm intrigued by this. Oh good, because in other sport 0:08:02.760 --> 0:08:06.040 oftentimes let's let's let's let's let's talk about tennis for 0:08:06.040 --> 0:08:06.400 a second. 0:08:06.400 --> 0:08:08.200 Okay, there's a new one I know. 0:08:08.960 --> 0:08:11.840 But the greatest player in the world maybe ever, Novak 0:08:11.920 --> 0:08:15.320 Djokovic thirty six years old right now. Everyone he's competing 0:08:15.320 --> 0:08:17.680 with is twenty twenty one, twenty two. One of the 0:08:17.720 --> 0:08:20.760 things he does best is he utilizes his body and 0:08:20.800 --> 0:08:24.520 his energy for the longest periods of time. So even 0:08:24.560 --> 0:08:26.440 if he loses the first set early to a young 0:08:26.520 --> 0:08:29.440 kid who's You're always like, watch out, dude, there's five 0:08:29.480 --> 0:08:32.960 hours left in this guy's tank. And what you're telling 0:08:33.000 --> 0:08:36.840 me is the best F one drivers manage their tire 0:08:36.920 --> 0:08:39.120 the same way correct And how do they do that? 0:08:39.320 --> 0:08:43.480 It's a learned skill. And yeah, I remember Hamilton back 0:08:43.480 --> 0:08:46.120 in the day having a year or so where he 0:08:46.240 --> 0:08:48.640 had to master the new Parali tire. They took him 0:08:48.640 --> 0:08:51.679 about a year. But yeah, some drivers are much better 0:08:51.840 --> 0:08:56.640 at sensing what they're doing to the tires, the slip angle, 0:08:56.800 --> 0:08:59.680 the entry speed, you know how much breaking, what their 0:08:59.720 --> 0:09:01.960 take out of the tires. And then you'll hear the 0:09:02.000 --> 0:09:04.800 engineers be like, okay, push push, push when you get 0:09:04.840 --> 0:09:08.040 near a pit stop, because then now you don't want 0:09:08.080 --> 0:09:10.040 any life left on the tires when you get rid 0:09:10.080 --> 0:09:12.480 of them, but you want them to last as long 0:09:12.520 --> 0:09:15.400 as you need to for the strategy of your particular race. 0:09:15.440 --> 0:09:17.240 Am I going to undercut the guy in front of me? 0:09:17.280 --> 0:09:19.640 Am I protecting against something from behind me? Do I 0:09:19.640 --> 0:09:22.320 think there's going to be a safety car? So you 0:09:22.400 --> 0:09:26.320 see radically different tire strategies, and often they're based on 0:09:26.800 --> 0:09:29.360 the abilities of the driver. If your driver's bad at 0:09:29.440 --> 0:09:33.480 managing tires. And by bad, please understand that's an incredibly 0:09:33.559 --> 0:09:36.440 relative bad. I couldn't do any of this. But if 0:09:36.440 --> 0:09:39.400 your driver's bad, you might think, Okay, it's better for 0:09:39.520 --> 0:09:41.760 us to aim for an extra pit stop and let 0:09:41.840 --> 0:09:45.600 them just really go to town rather than ask them 0:09:45.600 --> 0:09:47.439 to do something. They're not great at it, and it's 0:09:47.440 --> 0:09:49.280 going to make them unhappy, and then there's still not 0:09:49.320 --> 0:09:51.120 going to be great at it, so the strategy is 0:09:51.160 --> 0:09:53.560 not going to work anyway, And so that can be 0:09:53.600 --> 0:09:56.720 sometimes when you see same teams run different strategies with 0:09:56.800 --> 0:09:59.559 different drivers. Is going to be down to their abilities, 0:09:59.559 --> 0:10:00.320 and it can. 0:10:00.280 --> 0:10:01.320 Change from track to track. 0:10:01.440 --> 0:10:04.080 Sometimes travers will have a good week, sometimes they'll have 0:10:04.120 --> 0:10:06.800 a bad week, depending on on the types turns you have, 0:10:06.920 --> 0:10:11.240 the type of asphalt you have, what particular compounds. 0:10:10.559 --> 0:10:13.280 They've brought to the race. Oh, so many variables. I 0:10:13.320 --> 0:10:15.880 know they look different, but as it made of the 0:10:15.880 --> 0:10:18.200 same stuff, is just my road tires. You know what 0:10:18.280 --> 0:10:22.120 makes them special? Well, they're not even special because they 0:10:22.160 --> 0:10:24.920 obviously wear down so much faster than my tires. 0:10:25.360 --> 0:10:28.880 Well, they look the same, but what makes them different 0:10:29.280 --> 0:10:33.720 is the quality of the work. To a certain extent, 0:10:33.720 --> 0:10:37.439 they're all handmade, they're not built on a machine line. 0:10:37.600 --> 0:10:38.679 But the real. 0:10:38.520 --> 0:10:43.200 Magic though, is on the top. It's the compounds, and 0:10:43.360 --> 0:10:47.040 there you have your basic rubber, but you have an 0:10:47.160 --> 0:10:51.720 unknown mix of chemicals added at certain intervals that give 0:10:51.760 --> 0:10:56.160 it the consistency, the stickiness. So how soft is it, 0:10:56.880 --> 0:10:59.840 how long does it last? And what you also have 0:11:00.240 --> 0:11:03.200 n a raised tire often is you often have multiple 0:11:03.240 --> 0:11:06.400 compounds and a tread. So, for example, the inside shoulders 0:11:06.400 --> 0:11:10.600 of the tires will have a harder compound than the 0:11:10.640 --> 0:11:15.360 outside shoulders, and that's because the tires designed to roll 0:11:15.440 --> 0:11:19.440 over to that outside when it's taking all the weight 0:11:19.520 --> 0:11:21.520 of the race car and a turn, so you need 0:11:21.559 --> 0:11:23.760 it stickier there. But when they go down the streets 0:11:23.920 --> 0:11:26.800 usually they're angled up a little bit, which is camber, 0:11:27.200 --> 0:11:29.320 which means that you tend to do the most running 0:11:29.400 --> 0:11:32.440 on that mid to inside part of the tire. So 0:11:32.480 --> 0:11:35.800 they'll have different compounding across a tread, and they'll have 0:11:35.920 --> 0:11:39.480 different ways of making that compound, which is which is 0:11:39.520 --> 0:11:42.840 really an art and a magic and where a lot 0:11:42.880 --> 0:11:45.679 of this performance will come from compounds. 0:11:45.920 --> 0:11:47.760 Yeah, what does that mean? A compound? 0:11:47.840 --> 0:11:51.040 A compound is the combination of rubber plus the other 0:11:51.160 --> 0:11:54.800 chemicals that make up the tread of the tire. So 0:11:54.920 --> 0:11:57.800 in Formula one, they have at every race what they 0:11:57.880 --> 0:11:59.559 call the soft, the medium, and the hard. 0:12:00.000 --> 0:12:02.320 There's always a trade off, there's always for each tire compound, 0:12:02.320 --> 0:12:04.640 there's a benefit and a trade off as in life. 0:12:04.800 --> 0:12:08.920 Ye as in Mario Kart. Now you want the small, 0:12:08.960 --> 0:12:12.760 little tiny character. He goes faster, but if he gets 0:12:12.840 --> 0:12:15.559 knocked over, he flies out. Yeah, you know what I mean. 0:12:15.760 --> 0:12:17.920 Okay, I like that. I don't do Mario Kart. So 0:12:17.960 --> 0:12:20.160 that's a good that's a good good knowledge. 0:12:20.720 --> 0:12:21.240 Down for us. 0:12:22.000 --> 0:12:26.040 So soft tires they wear out much faster, but they 0:12:26.080 --> 0:12:28.920 allow you to go much faster as well. Copy and 0:12:28.960 --> 0:12:31.360 you've got the medium, which is middle of rich. It's 0:12:31.400 --> 0:12:34.400 your reliable tire. It neither goes faster nor does it 0:12:34.400 --> 0:12:36.880 wear out faster. And then, as you can imagine, there's 0:12:36.920 --> 0:12:41.400 the hard tire that performs less well but also lasts 0:12:41.440 --> 0:12:42.120 a lot longer. 0:12:42.760 --> 0:12:45.560 So will they start hard finish soft? 0:12:46.320 --> 0:12:49.880 It depends on their strategy, also depends on how well 0:12:49.920 --> 0:12:51.000 they did in qualifying. 0:12:51.240 --> 0:12:53.880 Start hard to finish soft. But I just said that, 0:12:56.320 --> 0:12:56.839 and this is. 0:12:56.920 --> 0:13:01.280 Now coming right, and then we're not done because as 0:13:01.320 --> 0:13:04.480 with all things Formula one, it's a lot more complicated. 0:13:04.800 --> 0:13:07.560 They actually have C zero to see five. They have 0:13:07.640 --> 0:13:11.559 sort of five different compounds, which is a various mix 0:13:11.720 --> 0:13:16.079 of these tread chemicals that they will use depending upon 0:13:16.280 --> 0:13:21.360 how damaging the asphalt is and how much energy is 0:13:21.400 --> 0:13:25.960 being put into the tire. So the more damaging the asphalt, 0:13:26.040 --> 0:13:30.079 the more energy Usually the harder the construction of tire 0:13:30.440 --> 0:13:33.559 they will go with. And by harder, it's all relative. 0:13:34.080 --> 0:13:37.439 None of these would last anywhere near anything you'd put. 0:13:37.360 --> 0:13:38.559 On your road car. 0:13:38.960 --> 0:13:41.640 And then we're not done because then there's the intermediate, 0:13:41.920 --> 0:13:44.120 and then is the wet tires for whend it's absolutely 0:13:44.120 --> 0:13:44.720 throwing it down. 0:13:44.840 --> 0:13:45.960 What's intermediates. 0:13:46.120 --> 0:13:47.880 That's when you use when it's slightly drizzling. 0:13:48.160 --> 0:13:52.040 Oh, for god's sake, it has a slightly drizzling tires, 0:13:52.800 --> 0:13:53.720 it's raining tire. 0:13:53.840 --> 0:13:56.520 That's the blue tie, and that's the green tire. 0:13:56.559 --> 0:13:59.080 So the intermediates are the first step you go to 0:13:59.120 --> 0:14:02.000 when it starts raining and you've lost too much performance 0:14:02.040 --> 0:14:05.160 on the slicks. And then if it's a real deluge, 0:14:05.760 --> 0:14:07.800 then you go to the full wet, which have tread 0:14:07.800 --> 0:14:11.000 blocks and voids that look a lot like what you 0:14:11.040 --> 0:14:14.760 see on your road car, and those again are mainly 0:14:14.840 --> 0:14:18.080 to keep the cars from aqua planing and also to 0:14:18.160 --> 0:14:21.200 clear what is like a bath hub a second per 0:14:21.280 --> 0:14:24.680 tire of water from the track, because the real thing 0:14:24.720 --> 0:14:28.080 that keeps people from racing is if there's too much 0:14:28.120 --> 0:14:31.000 water on the track, the car's aquaplane then it's unsafe. 0:14:31.080 --> 0:14:34.760 And you just got these really long, boring red flag periods. 0:14:34.800 --> 0:14:37.080 So getting the cars out on the full wets and 0:14:37.120 --> 0:14:40.360 clearing the track leads to racing again sooner. 0:14:44.680 --> 0:14:46.680 Okay, we need to take a quick pause and a 0:14:46.720 --> 0:14:48.440 quick break, and then we're going to get into the 0:14:48.480 --> 0:14:50.120 fascinating topic of tire rims. 0:14:50.400 --> 0:14:52.840 Wow, we are, We're going to really talk tires. 0:14:53.000 --> 0:14:53.920 We're gonna talk times. 0:14:54.560 --> 0:14:54.800 Great. 0:14:56.600 --> 0:14:58.760 Okay, back from a break, I feel. 0:14:58.480 --> 0:15:00.360 Ready to dive into some rims. 0:15:01.280 --> 0:15:04.680 They're the same for every car, same design, same material. 0:15:05.160 --> 0:15:07.600 Interestingly enough, that wasn't always the case. It used to 0:15:07.640 --> 0:15:09.200 be back in the day that the teams would create 0:15:09.240 --> 0:15:11.400 their own rims. But similar to what we were talking 0:15:11.440 --> 0:15:14.440 about in the previous episode, we realize that's actually not 0:15:14.520 --> 0:15:16.680 where we want the teams to be focusing their time 0:15:16.680 --> 0:15:17.000 and effort. 0:15:17.080 --> 0:15:19.040 I wish every baseball player, I'd use the same beat. 0:15:19.680 --> 0:15:22.320 Oh, I love that actually. Okay, so that's the first bit. 0:15:22.480 --> 0:15:26.160 The second thing is the wheel covers. They're plastic. But 0:15:26.320 --> 0:15:28.960 here's what's interesting about the wheel covers. Remember that episode 0:15:28.960 --> 0:15:32.040 where we were talking about sponsors and advertisement. You could 0:15:32.040 --> 0:15:34.160 have your face potentially on one of the wheel covers 0:15:34.160 --> 0:15:36.960 that we didn't actually talk about. McClaren have maximized every 0:15:37.080 --> 0:15:40.520 sponsorship opportunity in placement and they've actually got Google as 0:15:40.560 --> 0:15:42.160 a sponsor, and so we've got the Google colors on 0:15:42.200 --> 0:15:45.200 the rims. The wheel nuts, this is where it gets interesting. 0:15:45.400 --> 0:15:49.120 They're unique to each team, so every team develops their 0:15:49.160 --> 0:15:53.720 own wheel nuts. Every will not cost one thousand dollars, 0:15:54.160 --> 0:15:57.960 meaning that during a race weekend, teams can spend up 0:15:57.960 --> 0:16:00.880 to fifty thousand dollars justin wheel nuts. 0:16:00.920 --> 0:16:06.960 That's a kick in the nuts. It's just funny that 0:16:06.960 --> 0:16:09.240 it's like, hey, the rims were in charge of the rims. 0:16:09.280 --> 0:16:11.400 No one else can mess with the rims, but nuts 0:16:11.400 --> 0:16:12.960 have at it like it's. 0:16:12.520 --> 0:16:15.280 The fact that Prairie looks after the rims helps the 0:16:15.280 --> 0:16:17.920 flow of everything. The wheel nuts, the teams are actually 0:16:17.960 --> 0:16:20.200 interacting with them as they change the tires. And so 0:16:20.240 --> 0:16:22.840 if they're creating their own wheel guns and the wheel nuts, 0:16:22.840 --> 0:16:24.320 it's easier for the team to look after that. 0:16:24.520 --> 0:16:30.280 How many nuts are in a wheel? Tell me more 0:16:30.320 --> 0:16:32.120 about the wheel nuts the wheel nuts. 0:16:32.760 --> 0:16:36.120 It's actually a really interesting question because unlike road cars, 0:16:36.920 --> 0:16:39.240 F one cars have just one wheel nut in the middle, 0:16:39.240 --> 0:16:42.280 in the center. Again, to facilitate the changing of tires 0:16:42.320 --> 0:16:44.640 during the pit stop. Here's a guess for you. I 0:16:44.760 --> 0:16:46.920 had to change a tire on my own. I did 0:16:47.960 --> 0:16:53.520 like a pit stop challenge with red Ball, and to 0:16:53.560 --> 0:16:57.200 take off the tire with the gun, put it back on, 0:16:57.320 --> 0:16:58.800 change it, et cetera. How long do you think that 0:16:58.840 --> 0:16:59.200 took me? 0:17:00.080 --> 0:17:05.480 Well, takes them two seconds. Yeah, so I would say 0:17:05.640 --> 0:17:09.520 you are twice as bad as them. It's not for 0:17:09.520 --> 0:17:13.480 any other reason other than you're just a one person. 0:17:13.560 --> 0:17:22.000 So I would say four seconds. It was very bad. 0:17:22.400 --> 0:17:25.639 It was bad fourteen seconds because I mean they're heavy. 0:17:25.680 --> 0:17:28.119 Fourteen seven. Yeah, the wheels are really heavy, which is 0:17:28.800 --> 0:17:31.960 but the wheel gun like that was insane. I did 0:17:32.000 --> 0:17:33.879 not expect to have to put that much pressure and 0:17:33.920 --> 0:17:35.679 take it off, which just it's nice to do these 0:17:35.680 --> 0:17:38.360 small exercise you realize, just okay, you guys are doing 0:17:38.400 --> 0:17:39.400 a pretty solid job. Here. 0:17:39.560 --> 0:17:42.000 I'm looking at a wheel nut gun right now, and 0:17:42.760 --> 0:17:44.360 you know what it looks like. It looks like some 0:17:44.400 --> 0:17:47.480 Star Wars. Shit. Yeah, it's really insane. And they must 0:17:47.560 --> 0:17:51.080 all have their own wheel nut gun because they all 0:17:51.080 --> 0:17:52.639 make their own wheel nuts. But they all must use 0:17:52.680 --> 0:17:55.600 the same wheel nuts, don't they don't they kind of share. 0:17:56.520 --> 0:17:58.760 That seems like a lot to all invent your own 0:17:58.800 --> 0:18:01.520 wheel nut. Okay, so what else? We're not even finished 0:18:01.520 --> 0:18:04.240 with the tires. The rim wheel covers wheel nut. 0:18:04.440 --> 0:18:05.640 Should I continue? Yeah? 0:18:05.960 --> 0:18:06.600 Yeah, there's more. 0:18:06.800 --> 0:18:10.439 Yeah, FIA sensors. We actually just got off talking. You know, 0:18:10.640 --> 0:18:13.120 previous episode we talked at length about all the sensors 0:18:13.119 --> 0:18:16.919 and all the data. There's actually FIA sensors inside of 0:18:16.960 --> 0:18:19.520 the wheels that measures both the temperature and the pressure 0:18:19.520 --> 0:18:20.080 of the wheels. 0:18:20.119 --> 0:18:24.280 The teams themselves will run infrared sensors look at the 0:18:24.440 --> 0:18:28.000 tire surfaces and see how they are doing that way. 0:18:28.040 --> 0:18:32.960 They'll also run aerodynamics sensors because the tires I don't 0:18:33.000 --> 0:18:35.119 need to tell you, no, wait, I do need to 0:18:35.160 --> 0:18:38.679 tell you. The tires absolutely have a massive impact on 0:18:38.760 --> 0:18:40.120 the aerodynamics of the car. 0:18:40.320 --> 0:18:42.880 The front wheelwake will absolutely ruin. 0:18:42.680 --> 0:18:45.800 Your downforce if you don't manage it, and the rear 0:18:46.280 --> 0:18:50.240 if the sidewalls are too flexible, as Red Bull learned 0:18:50.240 --> 0:18:54.800 in twenty thirteen, it will absolutely ruin your diffuser performance 0:18:54.800 --> 0:18:57.679 and you will be nowhere because you get yes, i'm 0:18:57.720 --> 0:19:00.600 gonna say it, tire squirt, where the babble of the 0:19:00.600 --> 0:19:04.040 rear tire going around a turn sends air into your 0:19:04.040 --> 0:19:06.040 diffuser and keeps it from working correctly. 0:19:06.119 --> 0:19:07.919 And then there's something else, which is the barkut that 0:19:08.160 --> 0:19:10.800 records all the places the tire has been around the 0:19:10.840 --> 0:19:13.159 paddock if it's been used. It's helpful for both the 0:19:13.160 --> 0:19:16.560 regulations safety, but it also helps even the commentators to 0:19:16.680 --> 0:19:19.520 track which tire has been used if it's been used 0:19:19.560 --> 0:19:23.000 multiple times. There's another thing that you will see, or 0:19:23.040 --> 0:19:25.680 that you might not see tied to the tires, which 0:19:25.720 --> 0:19:27.280 is have you ever heard of wheel weights? 0:19:28.080 --> 0:19:28.240 No? 0:19:28.640 --> 0:19:33.359 Okay, so I'm going to botch this completely, but when 0:19:33.800 --> 0:19:37.639 these like please do. When Perelli put the tires together 0:19:37.680 --> 0:19:40.440 and prep all the tires for the teams, they make 0:19:40.480 --> 0:19:43.359 sure that the tires are properly balanced, because no matter 0:19:43.400 --> 0:19:46.120 how hard and perfect you try and make the rim 0:19:46.200 --> 0:19:48.480 and the tire and when you put it together, they 0:19:48.560 --> 0:19:50.600 might be off center and off balance ever so slightly. 0:19:50.720 --> 0:19:52.880 So they have a machine that sensors where it's off 0:19:52.920 --> 0:19:55.520 balance and it says it's off balanced by a gram 0:19:55.600 --> 0:19:57.560 or two grams, and so you have these little wheelwights. 0:19:58.000 --> 0:20:00.960 What's funny with this is the Queen of England used 0:20:01.000 --> 0:20:04.159 to use the same thing in her dresses so that 0:20:04.200 --> 0:20:11.120 they wouldn't fly up. And fun fact, two years ago, 0:20:11.160 --> 0:20:12.680 when I was in the paddock in Austin, I was 0:20:12.760 --> 0:20:17.400 wearing very bad mistake of short, flowy dress which got 0:20:17.400 --> 0:20:19.720 me into trouble a few times with the wind. And 0:20:19.840 --> 0:20:21.840 so one of my good friends who works at Preddie, 0:20:21.880 --> 0:20:23.639 was just like, I think, I know exactly how I 0:20:23.680 --> 0:20:26.480 can help you, and he ended up sticking wheel waits 0:20:26.560 --> 0:20:28.920 at the bottom of my dress so it wouldn't go anywhere. 0:20:29.600 --> 0:20:34.160 Yeah, another contribution of f one's technological advancements to our society, 0:20:34.160 --> 0:20:36.119 to our society, which of course was stolen by the 0:20:36.160 --> 0:20:41.000
