P
The “P” indicates the tire is for passenger vehicles.
Next number
This three-digit number gives the width in millimeters of the tire from sidewall edge to sidewall edge. In general,
the larger the number, the wider the tire.
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 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. 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.
