Two items should be a permanent fixture
in every glove compartment; a tire pressure
gauge and a tread depth gauge. Check the
tire air pressure (including the spare) regu-
larly with a pocket type gauge. Kicking the
tires won't tell you a thing, and the gauge on
the service station air hose is notoriously in-
accurate.
The tire pressures recommended for your
car are usually found on the glove-box door
or in the owner's manual. Ideally, inflation
pressure should be checked when the tires
are cool. When the air becomes heated it ex-
pands and the pressure increases. Every 10°
rise (or drop) in temperature means a differ-
ence of 1 psi, which also explains why the tire
appears to lose air on a very cold night. When
it is impossible to check the tires "cold," al-
low for pressure build-up due to heat. If the
"hot" pressure exceeds the "cold" pressure
by more than 15 psi, reduce, your speed, load
or both. Otherwise internal heat is created in
the tire. When the heat approaches the tem-
perature at which the tire was cured, during
manufacture, the tread can separate from the
body.
CAUTION: Never counteract excessive
pressure build-up by bleeding affair pres-
sure (letting some air out.) This will only

further raise the tire operating tempera-
ture.
Before starting a long trip with lots of lug-
gage, you can add about 2—4 psi to the tires
to make them run cooler, but never exceed
the maximum inflation pressure oil the side
of the tire.
