I have a new set of 31 Dura Tracs waiting to go on my XJ, I just need to finish my front end lift and on they go. If you are a member of Tread Lightly you can get $100 back from Goodyear. If you’re not a member it's only $25 to join so you still save some cash. I pasted the link below, pretty sure it’s good for any Goodyear Wrangler tires.
