ok guys, im new to this forum belong to another that isnt too much help so hopefully you guys can help me out. I have an 02 4dr 4x4 blazer I wanna put at least 20's if not 22's on it. I know 20's i wont need any modification but how about 22's? Also i was under the impression that with 20's i needed a 9.5' offset but yet i found 20's with a 8.5' offset! will they work or should i stick with 9.5'?? and what kinda offset should i use with 22's? required i dont need any modification to fit them?! Any other pointers or mods you guys recommend will be greatly appreciated! Thanks guys!

 

I think you have rim width confused with offset or back spacing. Your factory rims are 15x7.5 with 6" of backspacing. You will want to stick with the 6" of backspacing when you move up in rim diameter and the width of the rim will depend on the width of the tire you want to run.

Also, the lower the profile of the tire, the closer the treadwidth and rim width will have to be to each other.

 

What is a good width to run if you have 18"-20"s with low pro's? This is for future reference......when I have money.

 

ok now what offset should i use for a 4dr 4x4??? i remember someone saying that they got a rwd offset and it didnt work with 4x4? do i need to worry about a 20x8.5 or 20x9.5?? and i cant find the backspace for these 2 particular rims i like!
