A customer once described his old bias-ply tires as “riding on four basketballs.” He was not wrong. A lot of riders do not realize how much tire construction affects the ride until they try a radial on their side-by-side.
The Quadboss QBT889 35×10-15 (8ply) Radial Tires on MSA M51 Thunderlips Matte Black Wheels package puts a radial tire on all four corners. You get four tires, four wheels, lug nuts and center caps.
Radial versus bias-ply
Tires come in two main constructions. Bias-ply tires use layers that crisscross at angles, while radial tires run their cords straight across from bead to bead. In general, radials offer a more flexible sidewall and a flatter, more consistent tread contact patch. Riders often notice a smoother ride and better traction on hard surfaces, which is why radials have become popular on UTVs that see a lot of trail and road miles. Long days in the seat feel noticeably less punishing on a good radial.
An 8-ply radial
This Quadboss QBT889 comes with an 8-ply rating. That means a tougher carcass than a lighter-ply tire, which helps against punctures and cuts. Getting both radial construction and an 8-ply rating in one tire is a good combination for riders who want a smoother ride without giving up toughness.
Size and wheels
At 35×10-15, this is a tall tire on a 15-inch wheel. It adds ground clearance and presence while keeping a reasonable sidewall height. The MSA M51 Thunderlips wheels come in matte black, a finish that hides trail grime and gives the machine a dark, aggressive look.
- Four Quadboss QBT889 35×10-15 (8ply) radial tires

Is your UTV ready for 35s?
A 35-inch tire is a significant upgrade. Before ordering, check:
- That the wheels match your bolt pattern
- Wheel offset and its effect on track width
- Clearance at full compression and full steering lock
- Whether your machine needs a lift or portal setup to run 35s
- How the larger tire will affect your belt, clutch and axles
