Well guys I did a little experiment yestarday ( sorry no pics). I was in a bind of what to do for a full size spare. I didnt want to leave it in the back of my truck for someone to steal possibly and didnt want a bed mount and lose that space so, someone said they mounted it under the truck. Well ive got a 35s with dumped exhaust and it fit just fine. It obviously sticks out more but what do you expect. Just thought id throw this information out there.
