How big of a rim can i put on a 98 chevy blazer 4x4. and what is the wheel measurements?

 

stock rims are 15x7, 6' backspacing on 4x4s, 4' on the 2wds. Bolt pattern for both is 5x4.75.

As for how big...thats up to your wallet..The only problem is width of the tire. The biggest tire you can go is 30x9.5. Any wider or taller without suspension modification and you'll scrub wheel well.

 

well ive seen dubs on them and 22's, but u gotta go low pro on the tires....i hate low pro's,not that much thread and i would not recommend it. 18 with a higher # of tires exmpl; 225,50r18 and then drop it, it would make a killer combo. i got an 86 2wd im dropping possibly 3/4 or 2/3 with some 18 irocs or some other cool rims and beefing up da tires to a lil over reccomended sizing. thats cool!!! ill post pix as soon as i get da drop and all.
