I'm new to the forum. I've read a couple of threads on my question but I'm going to ask anyways. I've noticed that some of you guys out there that have the same truck as mine (2006 2500 crewcab duramax) had the tire size 265 75 16 for a stock size. my stock size was 245. So my question is if I put a 265 on, will it rub or do I need to put a leveling kit in. I don't want to crank up the torsion bars. it rides rough enough already. thanks.
