Inflation -- Tire Pressure
The Certification/Tire label. which is on the rear edge of
the driver's door, or on the incomplete vehicle document
in the cab, shows the correct inflation pressures for your
tires when they're cold. "Cold" means your vehicle has
been sitting for at least three hours or driven no more
than
I mile (I .6 km).
You can operate some vehicles at reduced inflation
pressures
only when you'll be carrying reduced loads.
On those vehicles, the minimum cold inflation pressures
for a typical reduced load are printed on the Improved
Ride Tire Pressure label located
on the driver's door.
Weigh the vehicle to find the load on each tire and see
the label for the
minimum cold inflation pressures for
that load.
