    STI Black Diamond Tire STI Tire and Wheel has released a diamond in the rough 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. The Black 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.

    STI Gorilla Silverback-XLite The Silverback-XLite takes most of the features of the original Silverback and puts them in a lighter and more value-oriented package. It still delivers maximum traction in deep mud from its distinctive, aggressive, widely spaced tread pattern, but with less bulk. The lugs range from 1.125 to 1.250 inches tall depending on tire size. This allows for smoother, more versatile performance when not slinging mud in your favorite bog. It’s easier on the machine, and when comparing costs, it’s also much easier on the budget.

Combine that with wide spaced lugs for easy clean out and a tough 6-ply carcass and you’ve got a tire that’s ready to tackle just about anything you can throw at it.
