minimum backspacing i can have
 

im putting a 6'' lift on my 98 4dr 4wd blazer and also getting new wheels and tires. i found a wheel that i really like. the lift kit recommends a 15x8'' wheel with a 5.5-6'' backspacing but the wheel that i like only has a 4.5'' backspacing. would it be a bad idea to put these wheels on or would it be ok. i like the pro comp rock crawler wheels.

You will be fine with the 4.5" bs.

thank you. will i see any wearing in the front end? ive looked at several posts of ppl with the same issue and am worried about that.
