Thanks MI2VA . I did look at the pinned section and did searches. I’ll keep searching.There are multiple threads on tires here. Look at the 'sticky' notes or do a search. Short answer is 31" diameter will be about the largest tire without any lift. Use a tire size calculator on tire rack web site to find the combination width height you want. You can go to a 32" tire if you do some trimming and have about 2" lift. The rear is where you have issues. I run Nitto Terra Grappler G2s 275/65R18 with 2" lift and rear wheelwell trimed.
