yea im running 275/65-20 at stock height to no problem

 

I ran 315-70-17 at stock height for a while and there was only a very occasional rub, so 275/65-20 will be absolutely fine.

 

Excellent tire choice for an A/T. Very good dry pavement rating, excellent rating on wet pavement, packed snow and ice. Very quiet tire on the road and is surprisingly adept at mild off-roading.
As long as you don't plan any heavy mud crawling or rock climbing, they will perform with about any tire out there. Not quite aggressive enough for me to have on my truck, but I have a set on my Grand Cherokee. The perfect tire for a daily driver that you take on the occasional fishing or camping trip on a weekend.

 

No offense brother, but where does that notion come from? Stock size for my truck is 33". 34" @ 11" wide can't be an issue.

I called a place here in town asking questions about lifts and tires. I told him I'd want 35" tires and he said "OMG, you can't do that without a lift". When I told him that the stock size was 33" he said "Oh, well... I didn't know that the Dodge stock tire was so big."

My truck is stock height and has a lot of room in the wheel wells. I'll probably end up not going with the 35" by 12.5", but I doubt there will be any issue with the 275/65/20 that is 34" by 11".

 

Even if you don't need a lift for the tire size, please at least level it for the sake of it looking like a 4x4!
