okay so sorry if im bugging you guys, but im curious now too. moog 5664s, 2" shackle on my '01 2wd. i should be able to squeeze 31x10.50s with some trimming right? also im thinking 15x8 wheel with 4.5 backspacing.

 

You will need to go with a smaller backspacing or you will rub the frame/sway bars turning
Or if you keep that backspacing, 30s would work

 

He might get away with the factory 4.5" back spacing on a 2wd. It depends on the tire too. If you go with an AT tire it has a more squared shoulder which will rub a lot more. If you go with an all-season or passenger tire you probably won't rub at all, even with a 31x10.

 

I didn't even see he had a 2wd lol.....ur right..he may get away with 31s with a rounded tire

 

Aww man im disapointed in my blazer now.. i read that i could fit 31x10.5r15 without any lift/mod... im only in high school and dont have a job so i have little money and no income.. i have about $300 now and im gonna keep saving till i have enough for destination firestone m/t!! but maby not the 31" ones now.... i have the 235/75 option tires on it though for now

 

Been doing some thinking....

Could I fit 31x12.50s on 15x8 (3"offset) wheels...with little to no trimming?

Again...I'll have:
2.5" shackle lift
Full T-Bar crank
PA 2" Body Lift

If not I'll stick with 31x10.50s

 

This is very simple.

If you want to fit 31's with zero problems, sell your Blazer and get a ZR2. Problem solved.

 

Real friggin helpful...

I was more concerned with the 12.5 width...31x10.50 will work with the lift and rim backspacing...

u one of those members who thinks you're billy badass with his ZR2?
remember I got this car for free... Why would I sell it and spend 1000s of more dollars on a zr2?
Way to think that one through
And zr2s don't come in a 4door for those of us with kids...

 

I really doubt you could do the 12.5" width without having to do some trimming on the fenders. In fact I'm positive you'd have to so some cutting on the fenders. With 4.5" or less of backspacing you should be ok and not rub on the frame though.

 

Thank you.... Exactly the info I needed...

The rims I am getting are 15x8 with 3" backspacing... Would I get away with that or just stick with 1050s
