Cross-terrain six-ply radial tire for utility ATVs and UTVs
STI Tire & Wheel has released its latest ATV/UTV tire – the Black Diamond.
“This super-versatile new ATV/UTV tire is designed to deliver crossover performance—an ideal choice for all terrain types and all seasons—at a value price,” STI says in a release.
According to STI, the Black Diamond’s “V” tread pattern bridges the gap between soft mud/snow/sand and hardpack surface capabilities. Its over-center tread elements are designed to provide a smooth, controlled ride on hardpack, while offering excellent traction and clean-out in soft conditions. The Black Diamond’s 6-ply radial carcass was developed specifically to provide the stability needed for side-by-side UTV applications, while retaining the plush ride characteristics favored by ATV riders. Also, STI says an extended-wear tread compound retains biting edges longer and greatly increases tire life.

The Black Diamond is now available in two models and more than 30 sizes. The Black Diamond ATR features a ¾-inch tread lug, while the Black Diamond XTR utilizes a more aggressive 1 1/8-inch lug depth.
The ATR model’s sizes are: 22x11R-9, 25x12R-9, 22x11R-10, 22x8R-10, 23x10R-10, 23x8R-10, 24x11R-10, 25x11R-10, 23x8R-11, 24x10R-11, 24x8R-11, 24x9R-11, 25x10R-11, 25x8R-11, 23x10R-12, 23x8R-12, 24x8R-12, 25x8R-12, and 25x10R-12.
The XTR model’s sizes are 25x8R-12, 25x10R-12, 26x10R-12, 26x12R-12, 27x9R-12, 27x11R-12, 26x9R-14, 26x11R-14, 27x9R-14, 27x11R-14, 26x9R-15 and 26x11R-15 (26x9R-12 and 26x11R-12 sizes are coming soon).
