So I just stumbled across a deal online that I think is pretty good and I'm thinking about picking them up this week. Its for a set of 5 Nitto Mud Grapplers 33x12.50 R20's for 125$. I'd say 4 of them have about 1/4 (maybe a little less ) tread life and one is brand new. I'm thinking about re-grooving them for my truck. Basically my truck is just for winter, to and from school with other driving occasionally, I'm hoping to get a couple thousand miles out of them. I'm curious if anyone had any experience or insight on this? Maybe some pictures as well. Let me know your thoughts. Thanks again everyone.
