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.

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.
