Um, what?
I'm flip-flopping. I was going to shy away from these tires because they're not XL rated, and I will be autocrossing on them (ie heavy lateral loads). But reading all the reviews and tests, they seem to hold up really well to spirited driving and have stiff sidewalls.
Obviously they're not the best tire money can buy, but when they're the top of their category (UHP Summer) and nearly half the price of the top of the next category (MaxP Summer), then they're definitely worth considering.
