Replacement Tires

A Tire Performance Criteria (TPC) specification number is molded in the sidewall near the tire size of all original equipment tires. This specification number ensures that the tire meets all performance standards for traction, endurance, dimension, noise, handling, rolling resistance, and others. Usually a specific TPC number 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 ride, handling, speedometer/odometer calibration, vehicle ground clearance, and tire clearance to the body and chassis.

WARNING: 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.

Inspect
- Tires should be inspected and replaced when the following conditions are found:
1. They are worn to a point where 1.6 mm (1/16 inch) or less tread remains or the cord or fabric is showing. To help detect this-tires may have built-in tread wear indicators that appear between the tread grooves when the tread is 1.6 mm (1/16 inch) or less. When the indicators appear in two or more adjacent grooves at three spots around the tire, replace the tire.
2. The tread or sidewall is cracked, cut, or snagged deep enough to expose the cord or fabric.
3. The tire has a bump, bulge, or split. Slight sidewall indentations are normal and should not affect ride.
4. The tire has a puncture, cut, or other damage that cannot be correctly repaired, because of the size or location of the damage.

NOTE: It is recommended that new tires be installed in pairs on the same axle. If it is necessary to replace only one tire, it should be paired with the tire having the most tread.
