What do you mean by it having a narrower tread width? Is it not at the normal 245 width typically?I just put on a set of the 255/40-19 Pirelli P Zero All Season Plus tires and I am extremely happy with the results. I went with a wider size to compensate for the narrower tread width on the Pirelli's. The ride is 100% better and much quieter than the stock Dunflops. Would have never known better if not for this forum. Best decision that I have ever made besides the Fast Intentions CBE and hopefully the Burger JB1 I have on order.
