If you have been driving your vehicle and think that
a tire is underinflated, fill it to the recommended cold
inflation pressure indicated on your vehicle’s tire
information placard or certification label. While your
tire may still be slightly underinflated due to the extra
pounds of pressure in the warm tire, it is safer to drive
with air pressure that is slightly lower than the vehicle
manufacturer’s recommended cold inflation pressure
than to drive with a significantly underinflated tire.
Since this is a temporary fix, don’t forget to recheck
and adjust the tire’s pressure when you can obtain a
cold reading.
Tire Size
To maintain tire safety, purchase new tires that are
the same size as the vehicle’s original tires or another
size recommended by the manufacturer. Look at the
tire information placard, the owner’s manual, or the
sidewall of the tire you are replacing to find this infor-
mation. If you have any doubt about the correct size
to choose, consult with the tire dealer.
Tire Tread
The tire tread provides the gripping action and
traction that prevent your vehicle from slipping or
sliding, especially when the road is wet or icy. In
general, tires are not safe and should be replaced
when the tread is worn down to 1/16 of an inch. Tires
have built-in treadwear indicators that let you know
when it is time to replace your tires. These indicators
are raised sections spaced intermittently in the bot-
tom of the tread grooves. When they appear “even”
with the outside of the tread, it is time to replace your
tires. Another method for checking tread depth is to
place a penny in the tread with Lincoln’s head upside
down and facing you. If you can see the top of Lin-
coln’s head, you are ready for new tires.
Tire Balance and Wheel Alignment
To avoid vibration or shaking of the vehicle when a
tire rotates, the tire must be properly balanced. This
balance is achieved by positioning weights on the
wheel to counterbalance heavy spots on the wheel-
and-tire assembly. A wheel alignment adjusts the
angles of the wheels so that they are positioned cor-
rectly relative to the vehicle’s frame. This adjustment
maximizes the life of your tires. These adjustments
require special equipment and should be performed
by a qualified technician.
Tire Repair
The proper repair of a punctured tire requires a plug
for the hole and a patch for the area inside the tire
that surrounds the puncture hole. Punctures through
the tread can be repaired if they are not too large,
but punctures to the sidewall should not be repaired.
Tires must be removed from the rim to be properly
inspected before being plugged and patched.
Tire Fundamentals
Federal law requires tire manufacturers to place stan-
dardized information on the sidewall of all tires. This
information identifies and describes the fundamental
characteristics of the tire and also provides a tire
identification number for safety standard certification
and in case of a recall.
Information on Trailer Tires
Why “ST” tires.
The physical requirements of “ST” trailer tires greatly
differ from those of “P” passenger tires. Passenger
tires are designed to maintain traction surface contact
during all driving conditions: pulling, stopping, turn-
ing, or swerving. Because of this, they are designed
with more flexible sidewalls to maintain tread to road
contact. Trailers have no driving torque applied to
their axles, therefore the only time trailer tires must
have traction is during the application of the trailer
brakes. Trailers also see heavier loads that typically
have a higher center of gravity then an automobile.
These conditions, along with inadequate torque
loads, and stiffer suspensions can cause swaying of
the trailer. Trailer tires are designed with these condi-
tions in mind and have stiffer sidewalls to help control
and reduce sway. For this reason, it is not recom-
mended that “P” Passenger tires be used on trailers.
Optimal trailer control will be achieved with “ST”
Special Trailer tires.
Industry standards dictate that ST tires are speed
restricted to 65 MPH under normal inflation and
load conditions unless a different speed restric-
tion is indicated on the sidewall of the tire.
WARNING
Replacement tires must meet the same
specifications as the originals. Mismatched
tires and rims may come apart with explosive
force and cause personal injury to yourself or
others. Mismatched tires and rims can also
blow out and cause you to lose control that
can cause an accident which can result in
serious injury or death.
