New Sizes and Finishes for STI's HD1 Series Wheels

STI Tire & Wheel has recently added two new finishes to its lightweight HD1 Series, for a total of three choices: the original Slik-Kote has been joined by new Machined and Black options.

As well, STI is offering new sizing for those new Machined and Black HD1 wheels. First offered in the 12×7 size, those finishes have been expanded to 14×7 sizing as well. That larger size significantly widens the range of customization and performance possibilities. According to STI, this taller size provides handling and ride advantages in most conditions. All STI HD1 wheels are designed to fit most popular utility/4×4 ATVs and side-by-side UTVs.

STI Releases Wheel Solution for Polaris RZR

Many off-road recreation areas and land management agencies currently limit vehicle width to 50 inches or less. This can present a problem for Polaris Ranger RZR 800 and 570 side-by-side UTV owners. Although these models meet the 50-inch-maximum trail restrictions as they come from the factory, STI says that no aftermarket wheels have been available to maintain that narrow legal width until now.

STI is now offering a new “Polaris 50-Inch Trail Legal” wheel alternative that utilizes a 6+1 offset to keep the standard RZR 800 and 570 to within 50-inch allowable limits. This 6+1 STI HD2 is available in 12×7 and 14×7 sizes with the Polaris 4/156 bolt pattern. According to STI, no other aftermarket wheel is offered in these specifications.

This same wheel will also benefit owners of Polaris Sportsman XP 850 and 550 ATVs. STI says it’s the only aftermarket option that keeps these models close to OEM dimensions (adding just two inches to overall width), which still provides plenty of clearance for most aftermarket tires and keeps them tucked in under the fenders to maintain good splash protection.

STI says its new wheel features a durable matte black finish with bright machined accents, topped with a tough matte clear coat. Like all STI HD Alloy series wheels, the HD2 comes with a lifetime structural warranty, made possible by he HD2’s unique inner and outer heavy-duty wheel lip reinforcement. The HD2 boasts load ratings of 700 lb. for the 12-inch size and 800 lb. for the 14-inch size. A matching HD logo wheel cap is included with every wheel.
