Argh, the dreaded yet familiar need for a C.R.A.S.H (Curb Rash Avoidance System (Hers))! I am just worried that if the wheels are curbed so often, the risk of blowing a tire would be worse, no? Plus the ride quality probably isn't going to be the best with such a short sidewall (as is being proposed). Anyway, I guess the question would be, would you need a stiff sidewall or a flexible sidewall to absorb the impact?
Would crossover/light truck tires like Yokohama Parada Spec-X or Pirelli Scorpion Zero work? They have a higher load rating (stronger sidewall), so maybe get one in the size you would want?
