I just picked up a set of 20" wheels off a 08 Ram. The factory tire size is 275/60/20. How wide can I go without it scrubbing on my 98 ram 4x4 with no lift? I'll get some pics up soon.

 

well... I have 285/75/15 and they rub so I'm guess ing you'rs will rub

 

They don't rub now with the factory 275/60/20 cut side to side.

 

I wouldn't exceed 11.5 inches on factory backspacing. I think after that you will rub on
the control arms. Just my 2 cents.

 

Well how much room are you talking. I personally wouldn't go much bigger if you did. iwhitne said he had 285/75/15 but he ment 16's. That comes out to a 33 and last time I checked the stock 275/60/20 was a 33 as well, but when I measured my buddys it came out to a 32. Use your own judgement, but like I said I wouldn't go much bigger if you did.
