Fitment
Fits UTVs running 15-inch rims with clearance for a 33 or 35-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 desert tires keep pinch flatting?
Hard hits crush the sidewall against the rim. The Sonora DS uses a reinforced Apex bead and D-Fense sidewall protection to resist impacts and pinch flats.
How do the two sizes differ?
The 33x9.5R15 uses 6x Kevlar bead to bead. The 35x9.5R15 uses a Nycore base with a Kevlar layer and a Kevlar belt to stay flexible and lighter for its size.
Is the Sonora DS DOT compliant?
MRT lists the 33x9.5R15 as DOT compliant. It does not state DOT compliance for the 35x9.5R15.
What rim size do I need?
A 15-inch rim for both sizes.
Can I mount these myself?
Use a tire machine or a shop, then balance before riding.
Sonora DS or Desert Storm?
Both are 8-ply Kevlar desert tires. The Sonora DS adds Kevlar bead to bead, D-Fense sidewalls and an Apex bead; the Desert Storm offers a 32-inch size and a deeper 25/32-inch tread.
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.
