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 RoTATIoN
For maximum mileage, rotate your tires every 5,000 miles. Follow correct rotation patterns.
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 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
Tread wear bars are raised sections built into the bottom of a tire's tread grooves that show
how much tread is remaining. When they appear "even" with the outside of the tread, it is
time to replace your tires.
The Penny & Quarter Test. Place a penny or quarter upside down into the tire groove. If
you can see the top of Lincoln's head, you are ready for new tires. If you can see the top of
Washington's head, tires are OK but close to wearing out.
