iv seen this video discussed on another forum and it was concluded that the most probably cause of the failure was not because of the stretch but because of the speed at which it was travelling, you can quite clearly see the tyre stretching (getting narrower) due to the speed and the fact he lifts off rather sharply which causes the car too dip and overload they tyre and it went boom

The car was pushed to this point to see the limits.

I think the tyre rating was W. So 180mph I believe.  The wheels where at 220+

Knowing that you cant say it failed because of the stretch.

Remind me to never do 223 in my golf

Talk about opening a can of worms

Running on the rollers will add extra load and friction.

Stretch will reduce the top end characteristics of a tyre compared to same tyre that is fitted to a wheel of the correct size, but in either case, it would be well beyond the legal driving limit, so therefore irrelevant
And yes, a can of Worms

Stretch is ok to a certain extent, but these scene queens running stupid stretch are just downright f**king dangerous and should have their licences revoked! I've seen it on another forum where a guy had them fail twice! Once was a pretty big sidewall blowout, and then about a month later the bead pulled off due to under inflation. Both times he was lucky, but would the Police see it as just unlucky if it had caused an accident, or would you see it as just unlucky if you had killed a young kid. I'll just leave that one out there for you all to ponder.............................

I had stretched tyres and did lots of miles no problem 195/45/15 on 9j and 185/45/15 on 8j with no problems except a hard ride

Then you're one of the bellends I was talking about.
