Hey guys, I just picked up a 2007 GMC Yukon Denali AWD and I'm looking into leveling kits. I understand that you can run a leveling kit (Rough Country 2") and not worry about changing angles, but where are you ordering the 1" blocks for the rears? Also, after adding the leveling kit, what is the largest wheel and offset you can run? I'm looking at the 33"/12.5/20" Atturo Trail Blade MT tires that actually measure about a 32.5" and 2 different wheels I'm going back and forth on. Can I run a 20x12 -44 or will there be too much rubbing/trimming? The other size is a 20x10 -12 (or -25 if they'll fit). Also, will the 33" tires that measure 32.5" fit, or will I need to order the 285/50/20 tires?
