John you are 100% correct.

The concept that the size of the rim dictates the sidewall height of the tire is incorrect. The size of the rim has absolutely NOTHING to do with ride firmness, form or function. It is determined by the sidewall profile and rubber compound of the tire. Simply put, you can run a 25 series sidewall on a 15, 16, 17 or what ever size wheel and it will give a rough ride. Consequently, you can also run a 50 series tire on a 22" rim and it will give a soft ride.

I'm not trying to come off as argumentative here, but this topic is one that is commonly replied to with misinformed or biased answers.
