DWT produces their Moapa-labeled
tire in both 8- and 12-ply carcasses for
UTVs, utility ATVs and sport ATVs.
The larger tires come in sizes 25x8-
12, 25x10-12, 26x9-12, 26x9-14, 26x11-
14, 28x10-14 and 28x12-14 and start
at $154.99 each. These 12-ply tires
typically weigh about 8–10 pounds
more per tire than an eight-ply setup,
so that’s still lighter than carrying a
spare tire and wheel. This tire is a
non-directional, aggressive tread patten that works best in hard-packed,
tacky or sandy terrain.
For sport quads, the run flat comes
with the XCF V3 nameplate. This yel-
low label, hard-compound, 12-ply tire
was developed for the desert racers
using 23x7-10 fronts and 22x11-9 rears.
Multiple Baja wins and champion-
ships have been taken thanks to this
product. The sport quad tires start at
Here you can see a run-flat tire (RP Advanced SOF) and a stock Maxxis Big Horn
tire, both without air. The wheel holding the standard tire is already digging into the
ground, while the run-flat is still inches off the ground.
