OK. In the other pic, the sidewall looked dirtier where the rim was bent, than around the rest of the tire, but maybe lighting. It's possible for the sidewall to rub a tiny bit, and still look new, aside from being a bit dirtier than the rest of the tire as well.

But yeah, if your tires were as low was 20psi on pressure, that's not good. Were they not visibly low with the car sitting on the ground, before you drove off?

They still have give... let the air out of a tire and see what happens Run flats are stiff enough to keep the their shape if the tire loses air.

No my tires were not low, that tire was mounted less that 24 hours earlier. My point was that i don't think a properly inflated 40 series tire can flex thatTN much that its doubled over. The tire is still holding pressure at 30 psi.

Have a look at this video by Michelin:

It seems that that video is advertising tires from Michelin that flex more to theoretically distribute the energy through out the tire rubber, rather than having it transmitted through the suspension and steering, as would happen with stiffer tires, specifically for the purpose of absorbing shock from potholes. Watching the "slow motion" portions of that video, I'm really surprised the wheels weren't damaged in it. The wheels were very close to full contact with the steel bars they used for the curb and pothole.

Precisely the point. A well designed video at a specific speed to show how the tire folds to absorbs the impact. A little bigger obstacle, a little more speed, an ordinary tire & you get a bent rim.

It's showing how a *specific* tire that is a little underinflated, and is designed to fold in a certain way, is folding to absorb the impact.

Anyway, I'm not disagreeing with the possibility. Just that that video makes me want to avoid Michelin tires.

Yeah this is all fun arguing academics, but I still have two damaged wheels that I need to go out right now and replace.

And I don't believe any video that talks about Tyres and Kerbs. What the heck are those anyway.

Did you try a google search on wheel repair? It's surprising what can be fixed; yours don't look too bad compared to some...

Yeah I did a search and there are many places right here in Houston. I'm going to try, but first things first. I'm trying to get the car ready for a show this weekend, and I'm going to need ANOTHER set of tires. My spare wheels from the back yard have tires, but they are not in top condition.
