I am putting new tires on my jeep i have 245's on now, and im just wondering if i went down to 225's or 235's would they still fit the rims that i have on now. im not going to go buy new rims so i can get new tires. im going to selling the jeep sometime soon and im just looking for decent cheap tires. so my question is typically how much smaller can you usually go when downgrading tire sizes.
