Pontiac 2006 Gto - Manual (Page 249)

How you load your vehicle affects vehicle handling and ride comfort. When driving with less than the maximum load
capacity allowed for your vehicle, you can set tire inflation pressure to the recommended amounts shown in the
following chart. Never load your vehicle with more weight than it was designed to carry.

Occupant and Cargo Weight:
470 lbs (210 kg) or Less

When to Check
Check your tires once a month or more.
Do not forget your compact spare tire. It should be at
60 psi (420 kPa). For more information about your
vehicle’s compact spare tire, see
Compact Spare Tire
on page 5-76 .
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t 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.
