Thanks Rammin! Those look awesome. I think they'll look great on a black truck on 20's.
I started off looking at the 35x12.5r20's but I found out they are MUCH wider than the 12.5" inches I thought they'd be. Nitto's website lists them as 13.39" wide.
I dont want any rubbing and dont want to have to push the wheels out too far so I think I'll go with the 295/65r20's which they list as 12.16" wide. Much better for the look I'm after and the fact that my truck will only be leveled.
