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 mile (1.6 km) after sitting for a minimum of
three hours. 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 approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking tire
pressure inside a garage, especially in the
Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(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 and within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, main
-
taining correct tire inflation pressure is very
important. Increased tire pressure and
reduced vehicle loading may be required for
high-speed vehicle operation. Refer to your
authorized tire dealer or original equipment
vehicle dealer for recommended safe oper
-
ating speeds, loading and cold tire inflation
pressures.
Recommended Cold Tire Inflation Pressures
For vehicle speeds below 100 mph
(160 km/h), recommended cold tire inflation
pressures are listed on the Tire And Loading
Information Placard located on driver’s side
B-Pillar or the rear edge of the driver's side
door.
When driving at speeds 100 mph (160 km/h)
and above, increased tire pressures and
reduced vehicle loading are required for
high-speed vehicle operation.
For driving speeds above 100 mph
(160 km/h) recommended cold tire inflation
pressures are listed below under "High Speed
Tire Inflation Pressure". Vehicle loading condi
-
tion must not exceed 688 lbs. (312 kg) (driver
+ three pass 88 lbs. (40kg) luggage).
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.
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 vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
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.
