just a couple questions.....will 2wd offset rims fit on on a 4wd?? i would like to know b/c when i get my 20s I wanna figure out a way to keep the rims from stick out past the fender

 

They will physically bolt up, but if the rims have the backspacing of typical 2wd rims, they will stick out around 2" per side further than 4wd rims.

 

so is there a way to get the rims to sit inside the fender? i know that the 4wd backspacing is 6"...if i go deeper will the rim rub the frame or wheel well??

 

You can't increase backspacing on rims that don't have enough. With a 4" (or close to that) backspacing, you will probably have problems with the rims hitting on the front and back of the fender while turning. The rims will physically be further away from the frame, but closer to the front and back of the fenders.

 

i know that much...i trying to figure all this out so i know what to order when its time for the new wheels....ive been told the new vette rims will bolt right up to the 4wd

 

Check the do it yourself section. Pretty sure there is a thread on what fits the S10 blazers in there.

 

yea it has a tire thread....nothing about rims that i found

 

Dont know what else to tell you.
Stock 4x4 rims are 15x7 with 6" of backspacing and 5 on 4.75' bolt pattern. What else do you want to know?

 

i just wanna know if the 6" of backspacing will keep the rims I want to get inside the fender or will they stick out?

 

if the rims are no wider than 7 inches and you have 6 inches of BS they will not stick out.... for every inch wider you go with a 6 inch BS the rims will stick out 1 inch....

an 8" wide rim with 6" BS will stick out about 1" farther than your stock rims do
a 9" wide rim with 6" BS will stick out about 2" farther than your stock rims.... etc
