Caution: Do not mix different types of tires on the same vehicle such as radial,
bias, and bias-belted tires except in emergencies because vehicle handling
may be seriously affected and may result in loss of control and possible
serious injury.
Important: Install new tires in pairs on the same axle. If you need to replace
only one tire, this should be paired with the tire that has the most tread.
A Tire Performance Criteria (TPC) specification number is molded in
the sidewall near the tire size of all original equipment tires. This number
ensures that the tire meets performance standards for traction, endurance,
dimension, noise, handling, rolling resistance, and others. A specific
TPC number usually is assigned to each tire size.
Replacement tires should be the same size, load range, and construction
as the original tires. Replace the original tires with tires that have the
same TPC specification number. Use of any other tire size or type may
seriously affect the following items:
| • | Speedometer/odometer calibration |
| • | Vehicle ground clearance |
| • | Tire clearance to the body and chassis |
Replace tires when you find the following conditions:
| • | The tires are worn to a point where 1.6 mm (1/16 in)
or less tread remains, or, the cord or fabric shows. The tires may have built-in
tread wear indicators that appear between the tread grooves when the
tread is 1.6 mm (1/16 in) or less. When the indicators
appear in two or more adjacent grooves at three spots around the tire,
replace the tire. |
| • | The tread or sidewall is cracked, cut, or snagged deep enough
to expose the cord or the fabric. |
| • | The tire has a bump, bulge, or a split. Slight sidewall indentations
are normal and this should not affect ride. |
| • | The tire has a puncture, a cut, or other damage that cannot be
repaired correctly because of the size or location of the damage. |
