new tires

[jblpower7]

i have a 99 4dr 4x2 blazer. i have a p235/75r15 mud tire on now. i need new tires but i dont know how big i can go without lifting the truck or hacking the fenders. i am looking at a LT235/75R15, 30x9.50R15, and a 31x10.50R15 BFG All Terrain T/A KO. i want the 31x10.50 but i dont want them to rub on the fender to much.
thank you for any help.

first off weclom to sic.

i have 245/70r15's on my blazer but its a lowered 4x4 and they only rub on the sway bar at full turn (i think its the sway bar). i knew some one with 31's on a blazer but they rubbed. i dont think it was on the fender it was just at full turn. i really dont think you will have much of a problem with the 30x9.5 or the lt235's. i'm not 100% sure because its a 4x2 but you shouldn't have a problem

do you have a lift on it? body or suspension

no lift but i was looking at the fabtech 4x2 blazer lift. but i heard they ride like crap, and i have the premium ride suspension.
