I have a question and need some help please.. I have found some pro comp extreme rock crawler wheels and they are 15"x8" wheel with 5x4.75 bolt pattern but they have 4.50 backspacing with 0mm offset.. would they fit on a stock blazer? I am running 31x10.50x15 tires!

 

Not without a lot of fender trimming(hacking really). It took me a 5" lift to fit them with 31" tires.

 

I love those wheels I have the exact ones . You have my size tires I can't believe you fit them I have a 2.5" lift those wheels need a lift
