To prevent injury caused by a bro-
ken socket, use only sockets made
for impact wrench use. Never use a
conventional socket.
When the tires are cool, inspect the condition and inflation
pressures per the Periodic Service Schedule. Always
install the valve dust cap after checking or inflating. When
removing wheels with an impact wrench, use only impact
sockets. Regular sockets are not designed for impact
pressures exerted by power tools.
A tire explosion can cause severe
injury or death. Never exceed infla-
tion pressure rating on tire side
wall.
To prevent a tire explosion, pressurize the tire with a
small amount of air applied intermittently to seat
beads. Never exceed the tire manufacturers recom-
mendation when seating a bead. Protect face and
eyes from escaping air when removing the valve
core.
Use caution when inflating tires. Due to the low vol-
ume of the small tires, over inflation can occur in
seconds. Over inflation could cause the tire to sepa-
rate from the wheel or the tire to explode, either of
which could cause personal injury.
Tire inflation depends on the type of tires installed, but
under no condition should inflation pressure be higher
than recommended on the tire sidewall. Standard and
optional tires should be inflated to the pressure desig-
nated on the tire sidewall. All four tires should have the
same pressure for optimum handling characteristics. Do
not over inflate. Due to the low volume of the small tires,
over inflation can occur in seconds. Install the valve dust
cap after checking or inflating.
Tire Repair
The vehicle is fitted with low-pressure tubeless tires
mounted on one piece rims.
The most cost effective way to repair a flat tire with a
puncture in the tread portion of the tire is to use a tire
plug.
NOTICE: Tire plug tools and plugs are available at
most automotive parts stores and do not require the
tire be removed from the wheel.
If the tire is flat, lift the vehicle and remove the wheel.
1. Lift the vehicle according to the lifting procedure
(See LIFTING THE VEHICLE on page 8).
2. Put the tire in water to find the leak, and mark with
chalk.
3. Insert the tire plug in accordance with manufacturers
specifications.
If the tire is being removed or mounted, the tire-changing
machine manufacturers recommendations must be fol-
lowed to minimize the possibility of personal injury.
To prevent injury, be sure the
mounting/demounting machine is
anchored to the floor. Wear OSHA
approved safety equipment when mounting/
demounting tires.
Follow all instructions and safety warnings provided by
the mounting/demounting machine manufacturer.
Wheel Installation
Do not tighten lug nuts to more than
75 ft. lbs. (102 Nm) torque.
NOTICE: Use the ‘cross sequence’ pattern when
installing lug nuts to ensure even seating of the
wheel against the hub.
1. With the valve stem to the outside, mount the wheel
onto the hub with lug nuts.
2. Position the wheel on the hub.
3. Finger tighten the lug nuts in a ‘cross sequence’ pat-
tern (Ref. Fig. 1).
4. Lower the vehicle onto the ground.
5. Continue to tighten the lug nuts to the torque value
specified below, in 20 ft. lbs. (27 Nm) increments, fol-
lowing the same ‘cross sequence’ pattern.
Item Torque Specification
Lug Nut 65 - 75 ft. lbs. (88 - 102 Nm)
