3.73 GEARS & O.D. Do I get 32 or 33\'s? 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.
