Diamond’s innovative “V” tread pattern bridges the gap between soft mud/snow/sand and hardpack surface capabilities. Its unique over-center tread elements 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. An extended-wear tread compound retains biting edges longer and greatly increases tire life.

STI Tire & Wheel has a proven performer with the HD Alloy C7 wheel. The eye-catching C7 features a machined finish with gloss black accents, protected with a tough clear coat. This stylish wheel is available in 12×7 and 14×7 sizes to fit most popular utility/4×4 ATVs or side-by-side UTVs.  

The one-piece STI HD Alloy C7 is surprisingly light, yet is so strong and durable that it carries a lifetime structural warranty—we build consumer confidence! The 12×7 has an impressive 700-pound load rating, while the 14×7 size boasts an 800-pound load rating.
