All Season Crossover

With two models and more than two dozen sizes available - including the new 28 / 10R14 XTR - Black Diamond tires are made for nearly every machine as well as every terrain. Both the Black Diamond ATR and XTR designs use over-center tread elements to provide a smooth, controlled ride on hardpack, while offering excellent traction and clean-out in softer terrain. The Black Diamond’s 6-ply radial carcass provides the stability needed for side-by-side UTV applications, while retaining the plush ride characteristics favored by ATV riders. An extended-wear tread compound retains biting edges longer and greatly increases tire life.
