You can find your
GAWR (Gross Axle Weight Rating), VCW (Vehicle Capacity Weight),
original equipment tire size, and recommended air pressure on a
placard located inside of the door edge, door post, glove box, or
inside of the truck lid
-
There are no blunt
objects made that are approved by any tire manufacturer for the
accurate gauging of air pressure. Hammers, bats, feet, sticks and
the like are not reliable. (Sharp objects are also out of the
question)
-
Only calibrated air
pressure gauges are approved and accurate for air pressure
monitoring.
-
Most tires will
lose air over time due to natural migration of air through the tire
casing (1-3 lbs month)
-
On radial tires, it
is usually not possible to visually determine that a tire is low on
air pressure
-
Air pressure
increases 2 PSI for every 10 degrees Fahrenheit above 60 degrees
-
Never bleed air
from a hot tire. Hot tires will typically read high air pressures,
therefore adjusting pressure at this time results in actual low
pressures.
-
Each tire size,
type, and brand has guidelines for air pressure and load adjustments
for their tires. Maximum pressure is not always best. It is only a
starting point for proper air pressure guidelines. Consult your
dealer for more information
-
Maximum of 5
percent difference in air pressure between a set of duals is
acceptable
-
Valve caps are
necessary to protect stems and cores from debris. Chrome caps
improve the look but that isn't their important function
