3.5.7 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 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.
3.5.8 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.
3.5.9 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.
3.5.10 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.
