The recommended cold tire inflation pressure,
shown on the label, is the minimum amount of
air pressure needed to support your vehicle's
maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the Tire and Loading Information label, see Loading
Your Vehicle on page 309. How you load your
vehicle affects vehicle handling and ride comfort,
never load your vehicle with more weight than it
was designed to carry.
When to Check
Check your tires once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inflated simply by looking at them. Radial tires
may look properly inflated even when they're
under-inflated. Check the tire's inflation pressure
when the tires are cold. Cold means your vehicle
has been sitting for at least three hours or driven
no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage firmly onto the valve to
get a pressure measurement. If the cold tire
inflation pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
inflation pressure is low, add air until you reach
the recommended amount.
If you overfill the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out
dirt and moisture.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor (TPM)
that sends tire pressure information to the Driver
Information Center (DIC). Using the DIC control
buttons, the driver is able to check tire pressure
levels in all four tires. See Tire Pressure Monitor
System on page 389 and DIC Controls and
Displays on page 208 for additional information.
