I'm curious myself. I bought 18x8 +38 and they look way more inset in the wheel wells than the original 20s. I was looking at spacers but now sure how safe they are on a truck this size.Hi guys. Any of you guys run steelies for winter tires? I just got some 18x7.5 +45 and the fitment seems really tight. Wondering if I should get different rims if possible or run spacers on them. What do you guys think?
