I run 27-10-12 Mud Lites on the front, and 27-12-12s on the back. 470 miles and several dozen miles of road riding and the wear is virtually nonexsistent. I did correct my alignment though when I got it. Most 500s come out of the crates with front end alignment WAY off... and it will eat tires like they're going out of style... on the road. Not to mention it makes steering squirrely at high speeds.
