I just picked up a set of rims and tires. They are Goodyear Tracker A-T size 10-15LT. It is about a 31x10.5. They are on original jeep cj rims. The tires are a bias ply that were the originals on the cj. They could be from the late 70's or early 80's, but are in great condition. The guy I got them from wanted $150, but ended up just giving them to me for free, with a 9-15LT spare.
