I run 18" simply because the tires and wheels are cheaper and the sidewall is more compliant on an 18" tire. Next time I will get the 305/45-18 vs the 305/35-18 I have now because of the height difference. The transmission sometimes gets confused because the wheel speed is different than the indicated speed and I don't have a tune to compensate for the tire swap.
