Tire Diagnosis

Poor handling

The problem may be

A tire that loses all or most of its air pressure must be removed from the wheel for a complete inspection to be sure it is not internally damaged. Driving for even short distances on underinflated tires may be dangerous & often damages the tires beyond repair.

Most punctures, nail holes, or cuts up to 1/4 inch confined to the tread may be satisfactorily repaired by trained personnel using industry-approved procedures. An on-the-wheel plug-only repair is not reliable & may cause further damage to the tire.

The proper repair of a radial tire includes the placing of a rubber patch on the inner liner of the tire by a professional. Do not attempt to have repaired tires with tread punctures larger than 1/4-inch, or any sidewall puncture. Also, do not have tires repaired that are worn below 2/32nd-inch tread depth.

Make certain that your spare tire is always ready to go into service. Check it regularly for proper air pressure & be sure that it is in good condition. If your vehicle is equipped with one of the several types of temporary spares, be sure to check the spare tire's sidewall for the correct inflation pressure, speed, & mileage limitations.


The problem may be

Tires of different size designations, constructions, & stages of wear may affect vehicle handling & stability. For best all-around performance, the same type tire should be used on all four wheel positions. It is also recommended that you NOT mix radial & non-radial tires on a vehicle. However, if mixing tires is for some reason unavoidable, NEVER mix radial & non-radial tires on the same axle. If two radial & two non-radial tires are to be installed on a vehicle, the two radials MUST be installed on the rear axle & the two non-radials on the front axle.
