The manufacturers don't recommend stretching tires because they have to plan for retards. If you curb check hard enough it will break the bead and your tire will deflate. Crazy... good thing that can't happen with non-stretched tires. Oh wait...

I've got 215/40-17s on a 17x9.5 on the front of my car. And it sees the track every drift event we have locally (even been out of state). I've not had any issues at all with the tires doing anything out of the ordinary. Stretching the tire gives it predictable characteristics on the track, removing the ability for the sidewall to roll negates having to correct for it.

You guys are arguing shit without any backing. I personally have experienced stretched tires on the track. I have personally pushed them past their limits and had no ill effects. You can argue that it's a style thing (and it partially is), but trying to claim that it doesn't work is stupid. I've never had a tire shop tell me they couldn't mount the tire, or wouldn't warranty it because of the stretch.

If you want to argue the science of it, please explain how having the sidewall strong enough to support the weight of the car under the pressure of air is any different at a 45 degree angle as opposed to a 90 degree angle. Seems to me that at a 45 degree angle it could spread the weight along the sidewall just as easily.

Also, Chance is right. Avoid pot holes. Clearly we take more pride in our cars and pay more attention while driving. Your argument there seems to be more that you don't want to be proactive in keeping your car looking nice. P.S. not stretching your tires won't save you from curb checks and pot holes. You can still fuck up your wheels.
