Tire Pressue Question

If the edge of the wheel itself is making contact with a road surface, then the tires are borderline flat, not just under-inflated. If a tire is that under-inflated (flat), then the tire is going to fail pretty quickly.

Garden variety under-inflation (i.e. 3-5 PSI under) is not going to cause a rough ride, nor cause the type of scenario you speak of.

It happens much more often with the larger wheels most cars have today. It doesn't take much deflection to roll a 2 inch sidewall.

Not with moderate under-inflation (3-5 PSI).

For that type of deflection to occur, again, the tire would have to be borderline "flat", not just under-inflated and would have to impact a pot hole or a speed bump. Low profile tires have stronger side walls to prevent the scenario you speak of, which is a reason to go with the tire manufacturer's PSI recommendation.

this has now entered ridiculously small point argument but i will just say that most tires that are under inflated are likely 10+ pounds.

I don't want to extend my semantic warrior crown so lets not quibble about flat vs under inflated.
