    I like the way 33's BFG AT's look but I dont want to be doggin around town or on hills, I plan on new vortec later but my 350 tbi still has life. Currently have 31's and it drives great. Im gonna lift it but want more rubber to fill the wells. Mostly onroad use and light towing. I live at 4500 feet and I have the Blazers' big brother (Suburban). Thanks.

    if you want bigger tires go ahead and get 33s. You would not notice a difference between 32 or 33 really. If you plan on towing you will want to go to 4.10s probably, better power. I tow occasionally with 33s and 3.42s and its a real dog. 3.73s will be fine for a while, just keep them in there and decide if you like them. Hope this helps

    I have 33s and 3.73. I don't use overdirve because when I do it shifts between OD and D constantly. All these shifts cause heat, and heat kills auto trannies. It works fine in drive.
