Possibly. Running stock rims? It will probably be really close to the bolt so you might have to run spacers. Your best bet is to go to a tire store and see if they'll fit one so you can check your clearance. That's the only way you'll know for sure. I know of a few people who are running 265/65/17 on stock suspension, but most are running spacers or after market wheels.
Clark, you are in the same boat I'm in. 18" rims on an 08 JGC, 245/60 on their now. Not the best selection for A/T at this size. What did you end up finding out with the 265/60's?
Does anyone else have any suggestions for A/T's tires?
