                                  Brooklyn Center, MN (4/19/2012) 
                                  – STI Tire & Wheel’s ultra-versatile 
                                  cross terrain radial tire, the Black Diamond, 
                                  is proving to be just as competent on race courses 
                                  as it is on rocks, mud, sand and snow. At tracks 
                                  from one end of the country to another, side-by-side 
                                  UTV drivers are realizing how much of a performance 
                                  advantage the Black Diamond can provide.
                                    
                                    For example, in the most recent World Off 
                                    Road Championship Series (WORCS) event at 
                                    Speed World MX in Surprise, Arizona, Nic Granlund 
                                    took his STI Black Diamond-equipped Polaris 
                                    RZR to a convincing victory in the highly 
                                    competitive SxS Production 850 class. This 
                                    former quad racing star from Las Vegas topped 
                                    a field of 18 cars in a race that lasted just 
                                    over 41 minutes. For this race Granlund had 
                                    his Black Diamonds mounted on STI’s 
                                    brand-new HD Alloy Beadlock wheels—a 
                                    smashing debut for the groundbreaking product.
                                    
                                    With three top-five finishes in four events, 
                                    Granlund now holds fourth place in the class 
                                    point standings (and he didn’t even 
                                    compete in the opening round).

                                          John Yokley placed seventh in the XC1 
                                          Modifed Class at Big Buck GNCC | 
                                  
                                  On the opposite side of the country, John 
                                    Yokley is showing how well the Black Diamond 
                                    works in the woods. Driving a Polaris RZR 
                                    XP 900 for Big Country Powersports, Yokley 
                                    is enjoying considerable success in Grand 
                                    National Cross Country (GNCC) racing. He and 
                                    co-driver Jarrod McClure got their feet wet 
                                    in UTV racing in this series—which takes 
                                    place at selected GNCC events—during 
                                    the first round in Washington, Georgia.
                                  
They placed seventh overall out of 46 entries, 
                                    also good for seventh in the XC1 Modified 
                                    class. That result was nearly duplicated at 
                                    the next round in Union, South Carolina, where 
                                    Big Country placed eighth overall and again 
                                    seventh in class in an extremely dry and dusty, 
                                    hour-long race. Thanks to this consistent 
                                    performance and tire reliability, the team 
                                    currently stands a promising sixth place in 
                                    season points.
                                    
                                    Shooting back to the western end of the nation, 
                                    the UTV racing effort of Auburn Extreme Powersports 
                                    continues to impress with its own impeccable 
                                    RZR XP 900. As you may recall, this team made 
                                    a splash at the recent King of the Hammers 
                                    event. The car was then entered in a Valley 
                                    Off Road Racing Association (VORRA) short 
                                    course event at Prairie City in northern California, 
                                    where it had a highly competitive battle in 
                                    progress until breaking a CV joint late in 
                                    the race.
 
                                  
                                  
                                  It’s activities like these—putting 
                                  a product through the wringer like only racing 
                                  can—that provides tremendous feedback 
                                  to STI engineers to help make future tires and 
                                  wheels even better. We’d say our current 
                                  level of development is already in the winner’s 
                                  circle.
