Tire Wear Analysis: Maxxis Bighorn LT285/70R17D

Rear Maxxis Bighorn with 15/32" of tread remaining.

Careful inspection of the tread confirmed what I’d thought upon initial scrutiny: It’s obvious which pair of tires had been on the rear axle of the turbo-diesel Cummins and which had been on the front. The rears were evenly worn but had about 2/32″ less tread than the fronts, an obvious result of the substantial diesel torque, loading, and type of use they received.

17/32" in the center of a front tire.

The additional tread in the centers of the fronts was nice, however the outer edges were unevenly worn due to poor front-end alignment, driving style, or both.

Below you can see there is 10/32″ of remaining aftermarket siping in the center lugs.

  1. A few rotations on a well aligned vehicle should get those tires back in shape. They’ll be quite serviceable for several thousands of miles. Nice purchase!
