My truck already has 17s on it and I would like to stick with them if I can for now, but i am very strongly considering 3 inch lowering shackles and dropping toe t keys all the way. I think my 285 33s will clear ok. If it looks too odd, I will probably go for some 20s in the future.
I rode in a truck towing a truck for 3 hours the other night. The truck towing was running 420 that were brand new. You could see the wear on the rear tires when we got to our destination. Also they were hot to the touch when we stopped. Not warm but hot.
Thanks guys! It is lowered, I have 2" Belltech shackles in the rear with front leveled to match. I plan on lowering front end a bit more since I have some clearance but I'm not one to want to cut or move any metal.
