I have a 2002 Blazer 4 door 4x4 with a 6 inch rough country suspension lift sitting on 31/10.50r15. I will be possibly putting 2 inch spacers on to midigate any frame rub but what is the biggest size can I upgrade to.

 

According to RC's website, you can go up to 265/75R16 with no issues. That being said, I would be willing to wager that you could get away with 32x11.50R15's with minor trimming up front.

Happy modding, and welcome to the board!

 

Lots of people run 33x10.5 or 33x12.5 with 6" of lift and a fair bit of fender trimming. Just depends on how much surgery you want to do on your truck.

What tires can I fit?

 

Is there a 2WD version of this thread? It'd help me tremendously lmfao

 

I was able to fit 33/12.50r15 on stock rims with 2 inch wheel spacers. I have no rubbing and did not have to do and cutting.

 

sure you fit 33s as long as you dont turn the wheel, also, what good are big wheels no suspension clearance?

 

I have full range of motion in the tires and suspension
