Hey all, It is time to replace the tires that got sliced a few weeks ago, and I need some advice from you. First, about my truck, it is a 1978 Suburban 4x4, SM465/NP205, 10bolt/12bolt w/3.73 gears, NO lift. I have trimmed the fenders for clearance, and test fitted 35x12.50x15s with no problems. The truck currently has 33x12.50x15s on it, and is used as a daily driver (80%) and trail runner, mostly fire roads, on the weekends. I do not have the money to upgrade the axles to 1-tons right now, so that is out of the queston. I have deceided I am going to use BFGoodrich AT ko's and my queston is , should I go with 33x12.50x15s or 35x12.50x15s? I really want to go with the bigger tires, but I don't want to break stuff either.
