I already posted this in the GD section but, I have just recently purchased a CCM Level Kit for my '08 LTZ. I've decided to get some 295/55/20 Nitto Trail Grapplers. Now I just need to decide on a rim size. I want to go with the rim that requires the least amount of trimming. I'd rather trim plastic over metal. My options are a 20x8.5 with a +10 OS, a 20x8.5 with a +35 OS, or a 20x10 with a -24 OS. Any suggestions on what would make this job the easiest? Thanks.
