NOTE: Make sure each wheel is installed on its

proper hub as noted in removing (the "rotation
arrow" must indicate forward direction of rotation).

2. Tighten in a crisscross pattern to 40 ft-lb.
CHECKING/INFLATING
1. Using an air pressure gauge, measure the air pressure
in each tire. Adjust the air pressure as necessary to
meet the recommended inflation pressure.

! WARNING
Do not operate the ATV if tire damage exists.
NOTE: If repair is needed, follow the instructions

found on the tire repair kit or remove the wheel and
have it repaired professionally.
NOTE: Make sure all tires are the specified size and

have identical tread pattern.
3. Check the front wheel toe-in and toe-out and adjust
as necessary (see Steering/Body/Controls - Front
Wheel Alignment).
4. Test drive the ATV on a dry, level surface and note
any pulling to the left or right during acceleration,
deceleration, and braking.
 NOTE: If pulling is noted, measure the circumfer-
ence of the front and rear tires on the pulling side.
Compare the measurements with the tires on the
opposite side. If pulling is noted during braking only,
check and adjust the brakes as necessary and recheck
operation (see Periodic Maintenance/Tune-Up -
Hydraulic Brake Systems).
5. Increase the air pressure in the tires with the smallest
circumference measurement until all tires are equal
in circumference.
6. Repeat steps 4-5 as necessary to ensure proper han-
dling.
