4.9.4 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.
4.9.5 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.
4.9.6 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.
4.9.7 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.
