Black Diamond XTR Tire by STI Powersport

The Black Diamond XTR by STI Powersport is specifically designed to take on dirt, rocks, mud and slosh. Unlike smooth factory tires, the first priority in an extreme terrain tire is a thick aggressive tread, and STI has outdone itself on that one. Tall, deep lugs, 1 ⅛ inch tread, and 6-ply rubber makes for a tough radial with excellent bite. An innovative “V” pattern prevents mud buildup, so your tires won’t lose any gripping power where most would get bogged down. And the over-center tread design means your rig can ride just as well on dry clay and caliche as it does down in the washouts.

Black Diamond XTR tires come in several sizes to fit your machine. And STI’s extended-wear compound adds even more tire life, so you can get plenty of high-mileage bang for your buck.

Black Diamond XTR Tire Features:

  • 27 sizes available, a range for ATVs and UTVs
