Well, I've decided I'm gonna take the plunge and get some slightly better tires than the AT's currently on the K5. I won't be lifting the truck, just using some zero-rates, and some fender trimming so I can fit 33's on the truck. I don't want to go any larger yet because I'm not ready to lift it, nor am I ready to upgrade the axles. The size I'm looking for is in the 33x11-33x12.5 range and the terrain my truck is normally found in is pretty much mud and wet sand. The current tires I'm considering are; Super Swamper Trxus M/T Radial (33x12.5) Pro Comp Mud Terrain (33x12.5) There are a couple others like the Super Swamper LTB (33x13.5) that I like, but they look a little wide for me to be able to fit them without lifting. I would greatly appreciate any thoughts on those two tires (and also if you have any other suggestions); I'm trying to keep my budget with at most ~$160 a tire (unless I can find some good used ones in my area).
