Burnouts' effect on Tires?

These two pictures where posted in a link on another thread in this forum.

Personally I have never done such an extreme burnout. Maybe the most would be 5 or 6 seconds sitting still with a slight amount of smoke or maybe a nice slide across a parking lot or something. I figured all burnout just wear tires down faster.

As shown in the pictures above, the tires just didn't wear down per se, but were destroyed. My question is what causes a tire to self-destruct other than just wear down? Excessive heat from the burnout?

Plus anybody have a good range on how many miles each second (or whatever unit you want) of a burnout wears off of a tire?

Well, when you spin the wheels they are scratched by the tarmac irregularities.. MUCH more than when the ROLL on it. Try to take a ball, make it roll on an airfield all day long and check out if it's worn out. The take it firmly and scratch it against the ground for a couple of seconds ;) I am sure the result will be different ;)

A lot of lines on that airfield... that M5 could have been burning rubber for a while, in which case im not surprised the tyres look fucked..

There are so many variables when considering how many miles each second would take from your tires that its impossible to say even roughly. Just a few things would be: the tread wear rating of your tire, how powerful the car is, how fast the tires are spinning, if you are going sideways, and the pavement you are on.

In the case of that M5, that car is very powerful, the car was most likely sliding sideways (that rips the chunks out a lot more than just going straight), and he was probably going for along time so the tires got softer as all the heat built up in them, which would explain why the tires were so beat up.

Normally a car is not going to have 500hp to abuse the tires with, and the M5 probably has soft tires anyways, so you probably wouldn't get that much wear...but anytime you do a burnout you are going to lose a lot of 'miles' of wear on your tires.

adding to what sentra_dude said: also consider your rear axle alignment. More Negative Camber will produce something like what you see on the tires pictured. More Positive Camber will wear the tires more evenly across the tire until it starts to lean out and the wear goes opposite of what is pictured.

Toe angle will change the wear too, but not as brutally as camber.

Then again, tyres chunking that badly from some burnouts is pretty bad... would you trust such a tyre for a prolonged 160mph blast down the feeway?

I have seen and abused Goodyear F1 SC's and not actually seen that kind of chunking from soft street compound tyres...

Are those RunFlats ???

You can destroy pretty much any street tire in 5 laps drifting on a circuit - or a 1 minute burnout ...

Some of my friends use cheap spare tyres/rims for burnouts, its the challenge to get them to pop :mrgreen:

[ViperASR]

what will also play a role is the surface that your doing the burnout on, what type of tires you have on the car, those 2 things will play the biggest role on what will be the outcome of the tire.

yea, take a look at the gravel pavement. the rocks and stuff jutting up from the road may have taken the chunks out of the tire.

Which are both pointless acts. So any surprise expressed by the driver would be a little odd.

But if you plan on driving you car back from soem place with tyres in that condition you might be in for a vibrating unballanced surprise.

I'm pretty sure the M5 doesn't have run flats. It doesn't even have a spare. In fact all BMW gives you is a can of sealant and the number to BMW roadside assistance. :roll:
