Rides great as all the previous PSS uses already know. The tires are about 1" taller in OD than the stock 225/35 & 255/30 RFT's. Fills up the wheel well nicely with no rubbing issues. Two fingers space at top - perfect. Looks like a real tire on the rims in place of those darn rubber band looking RFT's - IMO.




I do have to say that the looks are great

But, wouldn't changing the overall diameter require reprogramming/calibration, otherwise your speedometer would be off. Since you're diameter has increased, wouldn't you be going faster than indicated.
