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 information.
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 tread wear indicators
that let you know when it is time to replace your
tires. These indicators are raised sections spaced
intermittently in the bottom 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
Lincoln'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 correctly 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.
RECOMMENDATIONS
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 standardized 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 Passenger Vehicle Tires
P - The "P" indicates the tire is for passenger
vehicles.
NOTE: Passenger car tires are not
recommended for use on trailers,
because the capacity ratings are not
marked on the sidewalls of these tires. In
the event a passenger car tire is used, the
capacity must be derated by 10%.
Next number (Positions 2, 3 and 4) - This
three-digit number gives the width in millime-
ters of the tire from sidewall edge to sidewall
edge. In general, the larger the number, the wider
the tire.
