I'd say, since you don't specify what you have, get some sort of 33" tires, maybe all terrains if you spend most time on the road rather then off-road. Or, get stock tires from your dealer, either 32" or 33" - it really depends on where you go with your truck. I use 33" mud terrains, they're great off road, bit loud on the road but I don't care.

You will have to tell us what is your primary vehicle use.....
