i dunno about all that i have ht efuzions onmy car and have had for over a year and i run 35psi in them with no problems

 

I try to keep just 2-4psi over mfg recommended pressures. I've noticed uneven wear at higher pressures, and the pressures on the sides are a maximum pressure only. I run 32psi in my 17's, and 33-34psi in my 18's.
