I have an 04 Jeep Wrangler that is close to needing new tires. I don't go off road much anymore and I have a question or two about new tires. I have 15"x8" wheels with 265/75/15 tires on it now but I want to go a down a size or two mainly for cost. could I go down to a 235 or 245 with these rims? would it look ok, or would these tire sizes balloon out on the sidewalls and not be a good way to go? also, has anybody ever bought tires online? recommendations? thanks for any input.
