Ford 1998 F-150 Automobile User Manual


 
Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of
performance on the laboratory test
wheel than the minimum required
by law.
The temperature grade for
this tire is established for a
tire that is properly inflated and
not overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
SERVICING YOUR TIRES
Checking the tire pressure
Use an accurate tire pressure
gauge.
Check the tire pressure when
tires are cold, after the vehicle
has been parked for at least one
hour or has been driven less
than 5 km (3 miles).
Adjust tire pressure to
recommended specifications
found on the Safety Compliance
Certification Label.
Improperly inflated tires
can affect vehicle handling
and can fail suddenly, possibly
resulting in loss of vehicle
control.
