STI Yamaha Grizzly 300 Tire and Wheel Kit

Yamaha’s budget-friendly Grizzly 300 may not seem like a machine the aftermarket would get too excited about, but the folks at STI Tire & Wheel obviously feel differently.

STI has pre-mounted Black Diamond ATR tires (23x8R-12 in front, 23x10R-12 in back) to a set of 12×7 HD2 alloy wheels. STI says this combination—ready to bolt on and go—provides much more performance and style to the Grizzly 300. OEM dimensions are 22-inch tires on 10-inch wheels.

According to STI, the cross-terrain radial Black Diamonds are significantly more aggressive than the stock tires and work great in all conditions, plus they are one inch taller than stock, which increases ground clearance. As well, STI boasts its two-inch-larger HD2 wheels are a major upgrade from the Grizzly’s stock black steel wheels in both style and durability as they feature a lifetime structural warranty.

STI Grizzly 300 kits are available at finer ATV/UTV dealers everywhere, through MTA Distributing. For more information, visit
