Fitment
Fits UTVs running 15-inch rims with clearance for a 27.5-inch or 29.5-inch tire.
MRT tires are sold individually and fit by rim diameter, not by vehicle make or model. Confirm your rim diameter, the width your rim supports, and the tire clearance your machine has at full suspension compression and full steering lock before ordering. Fitment is not guaranteed on unlisted applications.
FAQ
Why do my tires slip when the trail changes from sand to gravel?
A tread tuned for one surface can struggle on another. MRT positions the Sidewinder / Viking as an all-terrain tire for sand, mud and gravel.
What is the difference between the Sidewinder and the Viking?
They are the two sizes of this tire: 27.5x9R15 is the Sidewinder and 29.5x9R15 is the Viking.
What rim size do I need?
A 15-inch rim for both sizes.
Will the 29.5-inch Viking fit my machine?
Check clearance at full compression and full steering lock. Fitment is not guaranteed on unlisted applications.
Can I install these at home?
Use a tire machine or a shop to mount them, then balance and torque to your machine's spec.
Sidewinder or Rally Snake?
Both are light 15-inch trail tires. The Sidewinder is 4 ply with a 1,140 lb rating; the Rally Snake is 27x9.5, 2 ply and offered in a sticky compound.
Why MRT Tires
MRT (Moto Race Tire) builds its UTV range around anti-puncture sidewall construction. Its race, desert and rock lines use Kevlar- or aramid-belted sidewalls, and several models are offered in a sticky compound for riders who need more grip. Dunes 2 Dezert SXS carries the MRT line alongside the wheels, lug hardware and repair gear you need to finish the job.
