Cadillac 2007 Automobile User Manual


 
A Tire and Loading Information label is attached
to the vehicle’s center pillar (B-pillar), below
the driver’s door lock post (striker). This label
lists your vehicle’s original equipment tires
and their recommended cold tire inflation
pressures. 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 366.
When to Check
Check your tires once a month or more.
Do not forget to check the spare tire.
For additional information regarding the
spare tire, see Spare Tire on page 492.
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 underinflated. 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.
Recheck 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.
