Your vehicles as they sit now!

Well in that case, some 20x10s with a negative offset would look good on there. Polished looks really against pewter. A buddy of mine has a pewter 00 with some polished GMC 20s and 305/55/20s and it looks great even tho they're not negative offset.
I had the "fun" of negative offset on my 90 I don't know how these trucks deal with a negative offset wheel

It's not bad, you just have to be more aware. But as long as you have quality hubs you'll be fine. People run x10s and x12s with -44 offset all the time with minimal problems. I'll be going x10s with a negative offset for my next set, I'll just put some Timken hubs on when I do
