1SS wanting to downsize to 18"

First two replies are wrong information. When you -2 the rim you have to upsize the sidewall making the overall diameter the same or close to it. Pm the forum sponsor tire rack rep.

Tire size is going to depend on rim diameter and width so figure out which rims you want.
