NOTE:
These guidelines do not apply to split rims. Some vehicle manufacturers restrict replacement of tires to specific brands, types, or sizes. High pressure temporary compact spare tires should not be used with any other rims or wheels, nor should standard tires, snow tires, wheel covers, or trim rings be used with high pressure compact spare rims or wheels. Attempting to mount a tire of one diameter on a wheel of a different diameter or flange type may result in serious injury or death. Only specially trained persons should de-mount or mount tires. Explosions of tire and wheel assembly can result from improper mounting, possibly causing serious injury or death. Consult the vehicle owner's manual or vehicle placard for correct size, speed rating, designation, and cold inflation pressure of the original tires. Do not exceed the maximum load or inflation capacity of the tire specified by the Tire and Rim Association When replacing tires, it is suggested that the replacement tires match or exceed the OEM speed rating designation. If tires of different speed rating designations are mixed on the same vehicle, the tires may vary in handling characteristics. Do not mix different speed rating designations on the same axle. Do not mix radials with non-radial tires on the same axle, as this may affect vehicle handling and stability. If radial tires and bias or bias-belted ply tires are mixed on the same vehicle, the radials must be on the rear. High-pressure temporary compact spare tires are exempt from this rule. Do not mix size or type (Run Flat, all season, performance, mud and snow) of tires on the same axle. If any flammable emergency tire inflation product has been used on a tire, consult inflation product, manufacturer's product information label for tire deflation procedures to avoid possible serious injury or death. In some vehicles, changing the tire diameter from factory-equipped size can affect drive ability, as well as the performance of ABS and other vehicle systems. Consult the vehicle manufacturer's specifications.
| Condition | Code | Procedure |
|---|---|---|
| Air pressure incorrect | B | Require repair |
| Bead broken | A | Require replacement |
| Bead leaking, caused by tire | A | Require repair or replacement |
| Bead wire/cord exposed | A | Require replacement |
| Cord or belt material exposed | A | Require replacement |
| Cord ply separations | A | Require replacement |
| Directional/asymmetrical tires mounted incorrectly | B | Require remounting and/or repositioning |
| Irregular tread wear, affecting performance | 2 | Suggest replacement |
|
NOTE:
Determine and correct cause of irregular tire wear.
|
||
| Load ratings less than OEM specifications | B | Require replacement |
| Mixed tread types (all season, performance, mud and snow) on same axle | A | Require replacement |
| Number of punctures exceeds manufacturer's limit | B | Require replacement |
| Out of balance | B | Require rebalance of tire/wheel assembly |
| Ply separation | A | Require replacement |
| Pull or lead, caused by tire | A | Require repair or replacement |
| Radial and bias or bias-belted ply tires on same axle | B | Require repair or replacement |
| Radials are on the front and not on the rear | B | Require repair or replacement |
|
NOTE:
If radials and bias or bias-belted ply tires are on the same vehicle, the radials must be on the rear axle, except for high-pressure temporary spares.
|
||
| Run flat damage | A | Require replacement |
| Shoulder cut | A | Require replacement |
| Shoulder puncture | A | Require replacement |
| Shoulder with plug | A | Require replacement |
| Sidewall bulge | A | Require replacement |
| Sidewall cut | A | Require replacement |
| Sidewall indentation | No service required or suggested | |
| Sidewall puncture | A | Require replacement |
| Sidewall with plug | A | Require replacement |
| Speed rating designations different on same axle | 2 | Suggest rotation or replacement |
| Tire and wheel assembly has excessive run-out | B | Require repair or replacement of appropriate part |
|
NOTE:
Excessive is defined as enough to contribute to performance problems. Match mounting may correct run-out. If not, require replacement of appropriate part. Refer to manufacturer's specifications.
|
||
| Tires with excessive diameter difference on an all-wheel drive vehicle or four-wheel drive vehicle | B | Require replacement |
|
NOTE:
Excessive diameter difference is defined as exceeding manufacturer's specifications or, if no manufacturer's specifications exist, with more than 1/4"" diameter difference.
|
||
| Tires with excessive diameter difference on the same side of a dual-wheel application | B | Require replacement |
|
NOTE:
Excessive diameter difference is defined as exceeding manufacturer's specifications or, if no manufacturer's specifications exist, with more than 1/4"" diameter difference.
|
||
| Tread area puncture larger in diameter than manufacturer's specifications | B | Require replacement |
| Tread missing pieces (chunking), exposing cord | A | Require replacement |
| Tread missing pieces (chunking), not exposing cord | 1 | Suggest replacement |
| Tread separations | A | Require replacement |
| Tube in tubeless tire | 3 | Suggest removal of tube |
|
NOTE:
Most manufacturers do not recommend tubes in tubeless tires. Inspect tire and wheel . Assembly to determine the reason for a tube in tubeless tire. Recommendation for repair or replacement should be based upon condition of tires and! Or wheel listed in these guidelines.
|
||
| Weather-checking | No service required or suggested | |
| Worn to tread wear indicators | B | Require replacement |
