Under-inflation is the most common
cause of failures in any kind of tire and
may result in severe cracking, tread
separation or "blowout", with
unexpected loss of vehicle control and
increased risk of injury. Under-inflation
increases sidewall flexing and rolling
resistance, resulting in heat buildup
and internal damage to the tire. It
results in unnecessary tire stress,
irregular wear, loss of control and
accidents. A tire can lose up to half of
its air pressure and not appear to be
flat!
It is impossible to determine whether
or not tires are properly inflated just by
looking at them.

Checking Tire Pressure
1. When you check the air pressure,
make sure the tires are cold
―meaning they are not hot from
driving even a mile.
2. Remove the cap from the valve on
one tire.
3. Firmly press a tire gauge onto the
valve.
4. Add air to achieve recommended
air pressure.
5. If you overfill the tire, release air by
pushing on the metal stem in the
center of the valve. Then recheck
the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the
spare.
NOTE
Some spare tires require higher
inflation pressure.
8. Visually inspect the tires to make
sure there are no nails or other
objects embedded that could poke
a hole in the tire and cause an air
leak.
9. Check the sidewalls to make sure
there are no gouges, cuts, bulges,
cracks or other irregularities.
