Tire Pressure

Tires need the correct amount of air
pressure to operate effectively.
Neither tire underinflation nor
overinflation is good. Underinflated
tires, or tires that do not have
enough air, can result in:
Tire overloading and overheating,
which could lead to a blowout
Premature or irregular wear
:
Poor handling
Reduced fuel economy for
internal combustion engine
vehicles
Reduced range for electric vehicles
Overinflated tires, or tires that have
too much air, can result in:
Unusual wear
Poor handling
Rough ride
Warning
(Continued)
Warning (Continued)
Needless damage from road
hazards
The Tire and Loading Information label
on the vehicle indicates the original
equipment tires and the correct cold
tire inflation pressures. The
recommended pressure is the minimum
air pressure needed to support the
vehicle's maximum load carrying
capacity. See Vehicle Load Limits 0 181.
How the vehicle is loaded affects
vehicle handling and ride comfort.
Never load the vehicle with more
weight than it was designed to carry.
When to Check
Check the pressure of the tires once a
month or more. Do not forget the
spare, if the vehicle has one. The
compact spare cold tire pressure should
be at 420 kPa (60 psi). See Compact
Spare Tire 0 298.
