STI Tire & Wheel will be an official WORCS sponsor for 2013 and will also offer considerable support to its customers throughout the nine-round series, which begins January 25-27 at Canyon Raceway in Peoria, Ariz.

STI has posted a contingency program valued at $78,000 to be spread among all ATV and SxS class winners in all classes – from Beginners to Pros, Youth to Adult – competing with minis, UTVs and the entire range of quad classes. Use STI Tech 4 XCs, Black Diamonds, or new Roctane XD tires on the way to the top of the results sheet, and you will earn credits toward future STI product purchases.
