The pressure should be checked and
adjusted as well as inspecting for signs
of tire wear or visible damage at least
once a month. Use a good quality
pocket-type gauge to check tire pres-
sure. Do not make a visual judgement
when determining proper inflation.
Radial tires may look properly in-
flated even when they are under-
inflated.CAUTION!
After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve
stem, which could damage the valve
stem.
Inflation pressures specified on the
placard are always “cold tire inflation
pressure.” Cold tire inflation pressure
is defined as the tire pressure after the
vehicle has not been driven for at least
three hours, or driven less than
1.6 km after a three hour period. The
cold tire inflation pressure must not
exceed the maximum inflation pres-
sure molded into the tire sidewall. Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary
with temperature changes.
Tire pressures change by approxi-
mately 7 kPa per 7°C of air tempera-
ture change. Keep this in mind when
checking tire pressure inside a garage,
especially in the winter.
Example: If garage temperature =
20°C and the outside temperature =
0°C then the cold tire inflation pres-
sure should be increased by 21 kPa,
which equals 7 kPa for every 7°C for
this outside temperature condition.
Tire pressure may increase from 13 to
40 kPa during operation. DO NOT
reduce this normal pressure build up
or your tire pressure will be too low.
Tire Pressures For High Speed
Operation
The manufacturer advocates driving
at safe speeds within posted speed
limits. Where speed limits or condi-
tions are such that the vehicle can be
driven at high speeds, maintaining
correct tire inflation pressure is very
important. Increased tire pressureand reduced vehicle loading may be
required for high-speed vehicle op-
eration. Refer to original equipment
or an authorized tire dealer for recom-
mended safe operating speeds, load-
ing and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle
under maximum load is dangerous.
The added strain on your tires could
cause them to fail. You could have a
serious collision. Do not drive a ve-
hicle loaded to the maximum capac-
ity at continuous speeds above
120 km/h.
RADIAL-PLY TIRESWARNING!
Combining radial ply tires with
other types of tires on your vehicle
will cause your vehicle to handle
poorly. The instability could cause a
collision. Always use radial ply tires
in sets of four. Never combine them
with other types of tires.
