I have a 2010 4x4 platinum. I will be having a 2.5" front level and 1.5" rear block added. I'm ordering either 20x9 wheels with a +20 mm or +1 mm offset. I need to know which tires would work with this rig, I'm looking at 285/65r20's or 275/65r20's. Nitto Terra Grapplers or BFG KO2's if that's important to know. So the two variables are which size tire and which size offset. I would rather not deal with trimming and don't want rubbing. If anyone has experience with this set up or any advice/suggestions it would be helpful!
