Maxxis Razr Blade rear Maxxis Razr Blade front STI Vortex front/rear RP Advanced Delta FX rear
different left and right tires are needed. The front tire is smooth, except for
two tall ribs that run around the circumference that allows the tire to
knife in on turns. This tire was
designed for sport quads, and there
are a ton of sizes available, including
front sizes: 19x6-10, 21x7-10, 22x8-10
and 22x8-12; and rear sizes: 18x9. 5-8,
20x11-8, 20x11-9, 20x11-10, 22x11-10,
22x11-12 and 26x11-12, which could
be used on a UTV or 4WD ATV.
The Dune Star rear is a V-shaped
paddle that can be used on the right
or left side of a 4x4 quad or smaller
UTV. It comes in 26x9-12 and 26x10-12
sizes. The front tires come in the same
sizes and are also two-ply. This tire is
relatively smooth, other than a rectangular knobby that runs the circumference of the tire and thick ITP
logos that are found on both sides of
the rib.
KENDA
www.kendausa.com
Kenda has two rear tire offerings
for sport quads: the original Gecko
and the Gecko Plus. Both have a V-shaped pattern that can be used as a
left or right tire. The Plus gets two
extra ( 10 total) 5⁄8-inch-tall paddles
running around the two-ply tire. The
Plus tire is only available in 21x11-10
sizing, whereas the standard Gecko
is available in 18x9-8, 21x11-8, 21x11-
9, 21x11-10 and 22x11-10 sizings.
For front-tire options, Kenda’s
smoothie is called a Dune Runner
and features a single 1⁄2-inch-tall rib
running around its circumference.
Sizes include 21x7-10, 22x8-10, 22x11-
8, 22x11-9 and 22x11-10. Dealers have
great deals on all Kenda tires.
Maxxis
(800) 4-MAXXIS, www.maxxis.com
While Maxxis covers the UTV world
well, both in aftermarket and OEM
products, they strictly sell their sand
tires to sport quad riders. This tire is
known as the Razr Blade. Front-tire
sizes are available in 19x6-10, 21x7-
10, 22x8-10, 22x8-12 and 18x9. 5-8, and
have two knobby ribs for precise cornering capability at any speed. For
the rears, offset V-shaped patterns
offer good hook-up, and the size
selection is just as strong—20x11-8,
20x11-9, 20x11-10, 22x11-10 and 22x11-
12.
The Razr Blade tire has improved
tremendously over the years and
works great under any sport quad. If
there was a quad that came stock with
paddle tires, the Maxxis Razr Blades
would probably be on it. Prices for
front tires start at $89, and the rears
max out at a reasonable $144.
STI
(318) 255-0049,

STI has one offering for sand enthu-
siasts who drive in the dunes instead
of ride, and it’s a good one. We have
tried this 27x14-11-inch tire up front
and 14 inches in the rear on our
Polaris RZR XP 900, and it works awe-
some. Called the Vortex V-Roll, this
sand tire is relatively light at 19. 4
pounds up front and only 21. 6 pounds
in the back.
STI has kept the prices of this UTV
tire reasonable. The front single-ribbed smoothie sells for $139.95, and
the V-shaped paddle retails for
$176.95 each. So unless you have 14-
inch wheels on your UTV, you will
have to buy a set, and STI has a great
selection to choose from.
RP Advanced
(503) 434-9446, www.rpadvanced.com
RP Advanced is the company that
brought us one of the first run-flat
tires that they exclusively designed
for the military. Their sand-dune
offering, the Delta FX, is just as
impressive. It’s a UTV tire measuring
27x10-14 for front applications or
27x13-14 for the rear in four- or six-ply. It has a staggered low profile, 5⁄8-
inch-tall paddles, and a round profile that should float well. A center
rib is also supplied on all tires to help
you travel over hardpack terrain if
needed. The front and rear four-ply
tires sell for $188 and $195, respectively. ;
