. Having said that, you're not going to notice a dramatic difference between 35 and 40 series tires, so don't worry too much about it. Just choose a tire with a relatively soft sidewall, like PS2s.
By the way, if you don't know how to calculate tire circumference, find a calculator online to determine the aspect ratio needed to match stock circumference for the widths you want. Good luck.
So would 255/35/19 in the front and 275/30/19 in the rear be good? Or should I make the rear 275/35/19? Thanks!
