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.

STI Polaris 50-Inch Trail Legal wheels are available at ATV/UTV dealers everywhere, through MTA Distributing. For more information, visit
