for impact wrench use.
Tire condition should be inspected on a daily basis. Infla-
tion pressures should be checked on a weekly basis
when the tires are cool. When removing wheels with an
impact wrench, use only impact sockets. Regular sockets
are not designed for impact pressures exerted by power
tools.

inflation pressure rating on tire sidewall.
To prevent tire explosion, pressurize tire with
small amount of air applied intermittently to seat
beads. Never exceed the tire manufacturer's rec-
ommendation when seating a bead. Protect face
and eyes from escaping air when removing valve
core.
Use caution when inflating tires. Due to the low
volume of these small tires, overinflation can
occur in a matter of seconds. Overinflation could
cause the tire to separate from the wheel or cause
the tire to explode, either of which could cause
personal injury.
Tire inflation should be determined by the condition of
use. For vehicles being used on paved or hard surfaces,
tire inflation pressure should be in the higher allowable
range, but under no condition should inflation pressure
be higher than recommended on tire sidewall. All three
tires should have the same pressure for optimum han-
dling characteristics. Be careful not to overinflate. Due to
the low volume of these small tires, overinflation can
occur in a matter of seconds. Be sure to install the valve
dust cap after checking or inflating.

Repair and Service Manual
Tire Repair
The vehicle is fitted with low pressure tubeless tires
mounted on one piece rims.
Generally, the most cost effective way to repair a flat tire
resulting from a puncture in the thread portion of the tire
is to use a commercial tire plug.
Tire plug tools and plugs are available at most
automotive parts outlets and have the advan-
tage of not requiring the tire be removed from the wheel.
If the tire is flat, remove the wheel and inflate the tire to
the maximum recommended pressure for the tire.
Immerse the tire in water to locate the leak and mark with
chalk. Insert tire plug in accordance with manufacturer's
specifications.
If the tire is to be removed or mounted, the tire changing
machine manufacturer's recommendations must be fol-
lowed in order to minimize possibility of personal injury.

to floor. Wear OSHA approved safety equipment when
mounting/demounting.
Follow all instructions and safety warnings provided by
the mounting/demounting machine manufacturer.
Wheel Installation
Do not tighten lug nuts to more than 85
ft. lbs. (115 Nm) torque.
It is important to follow the 'cross sequence'
pattern when installing lug nuts. This will
assure even seating of the wheel against the hub.
With the valve stem to the outside, mount the wheel onto
the hub with lug nuts. Finger tighten lug nuts in a 'cross
sequence' pattern (Ref Fig. 1 on page D-2). Then, tighten
lug nuts to 50 - 85 ft. lbs. (70 - 115 Nm) torque in 20 ft.
lbs. (30 Nm) increments following the same 'cross
sequence' pattern.
