In high-speed motorsport, tire failure can cause catastrophic vehicle dynamics, where loss of rear grip leads to violent rotation and multiple rollovers, especially when drivers are under heavy braking and cornering loads.

Huge Shunt for De Keersmaecker! | From the Vault | Hungary 2013Added:
Heat four race two, drivers taking the line, spectators waiting for the off.
Here's the lineup of the regular drivers.
Peter Hedstrom, Mats Lysen, Michael De Keersmaecker, and Knut Ove Børseth with Zoltán Vass. The local drivers have been quite impressive here as well. First time they've really mixed it with the regulars.
Who's going to take the hole shot then?
Very, very important here in Hungary.
We've seen lots of action at the FIRST CORNER. DECENT START BY ALL THE DRIVERS.
MATS LYSEN LOOKS TO HAVE GOT THE JUMP ON EVERYONE.
BUT A HUNGARIAN DRIVER JUST STICKS IT RIGHT UP THE INSIDE, SIDEWAYS INTO UH DE KEERSMAECKER. DE KEERSMAECKER LOADS OF CONTACT. HE DIDN'T LEAVE any room. He didn't really leave him any room there.
De Keersmaecker was a little bit cheeky and Vass is uh is not happy with that and he's stalking De Keersmaecker now.
Yeah, Vass really brave up the inside. I think once De Keersmaecker sent him there, he really got to give him a bit of space. Heavy contact. Mats Lysen away out in front. Børseth chasing down Lysen. Really wide. GOT ON THAT GRAVELLY STUFF ON THE OUTSIDE. THEY'RE JUST LOSING traction immediately. Yeah, that's where all the loose gravel gets swept from these four-wheel drive cars and De Keersmaecker and Vass now taking the joker lap, but I still think Vass is after him. I really do. So, into the hairpin, Mats Lysen and Børseth. Lysen struggling for traction again. He's not quite on that clean line. Really clean line appearing, Andrew. It's going to as the gravel gets swept away, it's going to get cleaner and cleaner and quicker and quicker and we can see the lap times are much quicker as the the gravel gets swept away. Børseth now challenging Lysen and uh it looks like he's got the place on him. Does he leave Lysen sideways? Oh, Lysen got a puncture. He's got a puncture.
Yeah, he can't hang on to it now. That's why he's struggling on the exit of these corners. Alongside Børseth, but he'd be nuts if he tried to go around there with only three wheels on the wagon.
Going to struggle on the brakes maybe.
Keeps the car straight, not too much of a problem. Dust in the background. Lysen tires smoking and away through the long left-hander. Knut Ove Børseth now then leads the heat. Lysen still in second.
Peter Hedstrom, Michael De Keersmaecker, and still with a little fight with the local driver Vass at the back. De Keersmaecker smoke from on left. I don't know if he's got a puncture or if there's uh bodywork rubbing if there's a bit of contact from from Vassel to the We've seen a lot of contact between those two. Leeson's doing a great job here. He continues got a right rear puncture. He's obviously remembering that it's race time not position that counts. So, he's going to keep it neat and tidy and you can definitely see in the Keys Motorsport there's heavy bodywork rubbing on that left rear tire.
So, he's just going to try and get it through to the finish up towards the first corner. A bit of bumper in the middle of the road there. Nothing too dramatic. Leeson really sideways with three wheels on the car on the long right-hander looking up ahead. The Keys back Oh, Leeson spins.
He spins. I don't know if he got a tap there from behind but he's in the barrier now. Where's he going to head off to?
Quick reverse. Three-point turn. Right underneath the paddock. The Keys back and down into the left-hander. Forsett and Hedstrom have both gone for the chocolate lap. Are they going to be able to pop out in front of the Keys backer or not? FORSETT ALONG SIDE HIM AND HE DOES. FORSETT JUST IN FRONT.
The Keys backer is going to be very lucky not to get a puncture. It looks like he's rubbing a lot on that lot on that left rear. We'll have to see how that goes. We will indeed. So, he's still there. He's done well. Heavy contact and he's been a great drive by him all the way through the heat. Not sure whose bodywork is in the road there. The bits hanging off everyone's cars. Forsett fairly smooth through there. Avoids part of Leeson's car sitting in the road. Into that CAR OH, THE KEYS BACKER REALLY SIDEWAYS. HE'S IN OH, IT'S OVER. IT'S IN THE BARRIER OVER.
TWO, THREE TIMES OVER. WHEELS OFF EVERYWHERE. OH, THE CAR'S A MESS. THE CAR'S A MESS. I hope the Keys backer's okay. He's a really big hit. Immediate red flag. No surprise there. That was a huge shunt to Keys backer. You could see on the run down to that very fast right-hander the left rear tire was already smoking a little bit more and as he turned in it's obviously let go. You can see here as he's turning to the right there's just no rear grip there and the car's gone into the wall and up and over. Super unlucky, Andrew. If the tire let go anywhere else, you know, he'd have got away with it but leaning on it hard on the tarmac and in he goes.
I really hope he's okay. It's uh that's not good. There he is. Yeah, it's game over. The car is it's damaged, of course. I think I go five or maybe four times roll over with the speed from 130 I think.
Yeah, the biggest problem we have a good start and small touch in the first corner.
But it's not the biggest problem but then we take the yokel up and local guy here push me in inside the corner and I think the tire going to be smoke. Now I push really hard but I want to stay in the front of the finals and the last lap we go in the fast corner.
The car slipped a little bit and I go off the throttle try to have the car not in the wall but I touch a little bit not hard and immediately the car go back in the other way four four or five times I think.
