I've been thinking about tires lately. I'm trying to figure out what ones to go with. My TJ currently has 31" all terrains on it. I've been very surprised at how well they do but it's coming time to put some serious meat under it. I'm planning on a lift (4" long arm and 1" body lift) so bumping up to 37" or so should not be a problem (your opinion on this is welcome also). But looking around, I have come across the Nitto Mud Grappler
and the Trail Grappler
I really like the Mud Grappler. Not only the looks, but I really think the large lugs would do well on the rocks. What do you think? Any input and suggestions is greatly appreciated.
