We have used this set up on both a narrow RZR 570 and on the wider XP 1000.
They both use a stock wheel with a very
narrow offset. The eight-ply Roctane
tire is bulletproof and provides consistent traction.
STI’s great-looking HD3 wheel has been
out for over a year now, but it wasn’t
until earlier this year until the narrow
6+1 offset was released. It keeps narrow machines narrow or long-travel
machines handling their best.
nearly 500 miles on the little machine.
For traction, we wrapped the wheels
with STI’s thick Roctane tires using
26x9-14 sizing. The tires gave the 570
a full inch of ground clearance and
did not widen the machine at all.
Actually, the wheel may be a fraction
of an inch narrower than stock, but
the widest part of the RZR is still at the
fenders where it measures 50 inches
Again, the wheel performed very
well and looked far better than the
stock black steel wheels. Even with
the taller tire and increased traction
the Roctanes offered, the RZR is still
super sporty and a blast to drive. If
you are looking to keep a trail-legal
machine as narrow as possible or
want to keep a long-travel machine
handling as precise as the manufac-
turers intended, STI’s HD3 trail-legal
6+1 offset wheels will do just that. Plus,
it will make any machine look better
as well. STI’s wheels and tires are
available pretty much everywhere.

❏ There has been a shift in wheel
sizes recently for two reasons. Long-
travel suspension on both ATVs, UTVs
and trail-legal, 50-inch-wide UTVs
now require a wheel that is different
than what we are used to. Typically,
ATV wheels have been close to a
center offset. Some machines may
have used a little more of a narrower
setup and some a slightly wider one.
IRS quads are even more different by
using a very flush rear wheel and a
more center or zero-offset front one.
Both the long-travel machines and
the 50-inch-wide models are trending
more toward the zero-offset or flush
wheel, both front and rear, currently.
The flush wheel can allow you to run
as long of a suspension arm as possible while still coming in under the
manufacturer’s intended width.
For example, if you took a 50-inch
RZR 800 or 570 and put a typical aftermarket wheel on it, most likely you
will now be too wide to fit through the
gates on some restricted trails.
STI’s latest HD3 wheel has taken
on the problem by introducing a
brand-new wheel with a narrow 6+1
offset. That means the 7-inch-wide
wheel has 6 inches of wheel extend-
ing inward from the hub and only
1 inch going outward from the hub.
This wheel is a cool-looking, eight-
spoke design with gloss black paint
throughout, except for a few raw-ma-
chined accents on top of each spoke.
The wheels are only available in a
14x7-inch size and for Can-Am and
Polaris bolt patterns. The standard
4+ 3 and 5+ 2 offsets are available in
every bolt pattern. The HD3 is also
available with a single beadlock.
We have seen prices at places such
starting as low as $70 each.
We’ve been using the new trail-legal wheel for a few months now, and
we can tell you it is tough. While not
totally intended for the RZR XP 1000,
we ran a 125-mile desert race with
the wheel, and it performed flawlessly. On that car, the stock wheels have
a similar flush offset, and we didn’t
want to upset the handling any or put
any unneeded strain on the steering
components. It worked very well for
that extreme situation.
Our full test took place on a Polaris
RZR 570, where we replaced the stock
steel wheel with a full set of the HD3
6+1 offset wheels and took it for a
ride. Actually, we rode the machine
in several western states and put
