I currently have 35x12.5r17 Toyo ATs on stock rims on my truck. I recently added a 6"lift and wanted to go to bigger size tires on 20x9 rims, 0 offset/5"backsapcing. I have seen multiple posts saying that 37x12.5R20 will fit without fender trimming and others that say they need to be trimmed. Does anyone have any first hand experience? Will 37x12.5R20 Nitto Terra Grapplers G2 fit without trimming? Nitto website says they are 36.5" tall. or should I go with the Nitto's in the 325/60R20 size, 35.35" tall? Again, I am not looking to trim my fenders.


Thanks-D

I have fit 37x12.5x17 on stock wheels on my 2006 with a 3 inch lift with no rubbing. I do have 1/2" longer than stock control arms with helps for not rubbing, now I do rub the control arms because I am on stock wheels. For me not to rub I need to run 4 1/2" back space.

I'm running 37" Cooper STT Pros on a set of Fuel 20s with a 6" lift on my 08. They do rub the inner fender in the front when turning if you hit a bump just right.
