MAINTENANCE PROCEDURES
Tire Pressure
Use the recommended cold infla-
tion pressure for optimum tire per-
formance and wear. Under-inflation or
over-inflation may cause uneven tread
wear patterns.
Recommended tire inflation pressure
is found on the Tire Label located inside
the right side service cover.
When weather temperature changes
occur, tire inflation pressures also
change. A drop of 6°C (10°F) can cause
a corresponding drop of 1 psi (7 kPa)
in inflation pressure. Check your tire
pressures frequently and adjust them
to the proper pressure
NOTE: The pressure difference be-
tween the left and right side tire should
not exceed 3.4 kPa (.5 PSI).
Tire Damage
Check all tires for:
– Cuts, slits and cracks in the tires.
– Bumps or bulges in the side of the
tire or the tread.
– Nails or other foreign objects in the
side of the tire or tread.
– Air leaks (hissing sound) caused by
an ill-fitting rim or a faulty tire valve.
If any of the above occurs, have the tire
repaired or replaced as soon as possi-
ble by an authorized Can-Am On-Road
dealer.
Tire Tread Wear
Check minimum tread depth by using
the tread-wear indicators (hard rubber
bars molded at the base of the tread;
1 in figure below). Check in three loca-
tions across the tire tread:
– Outer edge
– Center
– Inside edge.
The tread-wear indicators will appear
across the treads that have been worn
down to the minimum tread depth.
When at least one tread-wear indicator

appears across the tread, have the tire
replaced as soon as possible by an au-
thorized Can-Am On-Road dealer.

TIRE TREAD WEAR
1. Tread-wear limit indicator
A. Appropriate tread depth
B. Minimum tread depth, replace tire
It is normal to see uneven wear on tires
depending on how the vehicle is driven
and road conditions. The front tires
external or internal edges and the rear
tire center tread will wear unevenly
depending on if the vehicle is driven
smoothly or aggressively.
Tire Rotation
Rotate front tires when tread depth
reaches 4 mm (5/32 in). This will maxi-
mize tire life.
WARNING
The tires are designed to rotate
only in one direction. Do not
switch the left and right front
wheels. The tires must be dis-
mounted from the wheels for tire
rotation. If a tire is mounted on the
incorrect side, you will have less
traction and could lose control.
CAUTION Do not hold the front
wheel spoke while attempting to
spin the front wheel as your fingers
may be caught between the wheel
and the brake caliper.
