    My burban has a 350/400turbohydromatic, NP 203, and 3.73 gears (open diffs I believe, and I plan on leaving them that way). Will 36x12.50 tsl's be too much tire for this gear setup. I don't plan on any crawling, all just medium speed muddin down old logging roads, and an occasional drive into town. I have known some people that ran 40's with stock gears, are they retarded, or can you get away with that much increase without gears? I've never ridden in a truck with large tires and stock gears, will it feel sick and lugged down? Any input on what I should do would be greatly appreciated.

    could I go bigger than 36's? I want something pretty big for the mud, but I still want the power to clean the tires.

    I had a 91 1/2 ton burb with 3.73's on 35's for most of its life and always felt it was underpowered and needed deeper gears.... I went through 10 bolt axles like crazy as well.... never broke a shaft just destroyed carriers and pinions I would reccomend a 14ff for a truck this heavy and no tires larger than 35 with those gears....it can be done but I wouldn't do it again
