The outside of OMF’s new HP1 High
Positive Offset wheel sits almost flush
with the wheel hub, similar to stock
wheels that come on most long-travel
UTVs. This wheel puts less stress on
items like spindles, wheel studs and
shocks. OMF can also put beadlocks on
your stock wheels as well. To find out
how, call them at (951) 354-8272.
The lugs on the Hammer provide great
protection from sharp rocks and sticks
across the contact patch and partially
down the side wall. The triple-belted
Kevlar carcass takes care of the rest.
The center lugs measure 3/4 of an inch
tall and are pretty slick, which wear
quicker than some tires.
❏ The tire wars are going full steam
ahead right now. We are not talking
about 18-inch MX tires or big lugged
mud tires; these are 30-inch UTV tires.
The most popular aftermarket tire
choice for the 1000 high-performance
sport machine is 30x10-14. However,
some of us don’t like to follow the norm,
and so we searched out something different. Instead of just putting the new
Moto Race Tire Hammer tire to the
test, we tried to create a tire and wheel
package that would complement each
other and provide a great end result.
MOTO RACE TIRE
This relatively new company has
hit the UTV market hard, offering a
good variety of all-terrain tires with
an eclectic choice of sizes. What
caught our eyes is the 30x9. 5-15. The
reason is that not one of the 1000cc
machines available right now needs
a full 10-inch- wide tire up front. None
of the manufacturers run that wide
of a tire up front as stock equipment.
Plus, in most cases when you wrap
your new tire around an aftermarket
wheel as most people do, those wheels
are wider than stock and affect the
handling. Furthermore, adding more
rotating weight further from the engine
actually slows a machine down.
The Hammer tire we are using is
DOT compliant, is an eight-ply and has
a 1330-pound load rating. It’s priced
at $265 each through www.moto
racetire.com. They claim the 30x9.5-
15 tire weighs in at 36 pounds, which
puts it about right in line with the
other popular tires out there but
about 7 pounds heavier than the stock
Maxxis Big Horns. For comparison,
we weighed an eight-ply 30x10-14
Duro tire, which has the same tread
pattern as the stock Maxxis Big Horn
tires, and it only weighed 29. 6 pounds.
One of our favorite tires in this size
category, the ITP Ultracross R-spec,
weighs in at 33 pounds.
For this tread style, only one size is
available. The company does have
a handful of other styles and sizes
available including a mud option.
According to Moto Race Tire, this
product is triple armor belted with
Kevlar and eight-ply rated, so we
expect it to be tough.
Included in this test we are trying
out OMF’s brand-new High Positive
Offset (HPO) wheel, which is as close
to stock as you can get as far as offset.
The wheel is actually sold as 14 or 15
inches tall and only 5. 5 inches wide.
So with the 30x9.5 tire mounted up,
the package gives it a wide, rounded
buggy-tire look. The HPO wheel sells
for $399 and is available for Polaris or
Can-Am bolt patterns. OMF has also
recently released a conversion they
can do, turning your stock Polaris
14-inch wheel into beadlock for a sig-
nificant cost savings.
To put some miles on this tire
combo, we equipped our Desert ver-
sion RZR with the complete set. We
used this machine on a pre-runner
at a local desert race, so it was easy
to put a lot of miles on the tire quickly
in a variety of tough terrain. For most
of the day we took it easy on the tire
and just learned the course and mon-
itored tire wear.
Like most tires we test on the RZR,
the rear was showing a bit more
wear than the front, even though
we drive strictly in four-wheel drive.
The grip was excellent, the 3/4-inch-
tall lugs were very predictable and
the wrap-around lugs gave excellent
side bite. What we liked even more
was the rock deflection. The rounded
tire soaked up the rock extremely
well, and we didn’t feel a disadvan-
tage of flex, even though we were
running a lower-profile 15-inch tire.
The tire’s weight didn’t seem to be
an issue as far as dragging down the
motor, but we did feel that the shocks
might have been working extra hard,
especially on rebound.
For our last three laps ( 100 miles)
of pre-running we tried to abuse the
tire. We aimed for the sharp rocks
and slide sideways over all the
embedded ones. The tire performed
excellent. We never caught an edge,
nor did we cut a tire down. Upon
further inspection, we didn’t see any
slices, punctures or close calls. We
did notice a bit more rear-tire wear
than we have seen with other tires,
but it wasn’t excessive.
The Moto Race Tire Hammer per-
formed well. We couldn’t puncture
it even when we tried. The traction
was predictable and very control-
lable. The only downside to the tire
may be its weight, but in most situ-
ations having flat protection is a lot
more important, and the Hammer
provides exactly that. We are going
to keep these tires on our Desert RZR
for a few more months and see how
well they are looking after the 500-
mile mark, and we will report back to
www.dirtwheelsmag.com with those
results. If you can’t wait that long,
give Moto Race Tire a call at (844) 884-
9759 and tell them Dirt Wheels sent
ya. Do the same thing when you call
OMF to order you High Positive Offset
wheels. They will keep your RZR turn-
ing sharp and predictably. Call OMF
Performance at (951) 354-8272. ❏
