My biggest issue with this tire on a 20 inch rim is its sensitivity to poor roads. I have burned through three of these tires in a year and have not had a major pot hole hit... just poor Chicago roads. Always the same thing... large bubbles in the side wall from impact damage. Like most people, I understand that if you hit a good pot hole you will have tire issues no matter what tire you have... this is only compounded when you run 20 in. rims. My advice is to buy this tire as a run flat if you run low profiles. This is a great driving tire, but it does not hold up well to poor road quality.
