Tyre defects
| Wear | Cause |
| Severe wear on both sides of the working surface | Insufficient pressure |
| Severe wear in the middle of the working surface along the entire circumference | Very high pressure |
| Uneven wear on the sides of the tread | Static and dynamic wheel imbalance. Large rim runout, large clearance |
| Uneven wear in the middle of the tread pattern | Static wheel imbalance. Consequences of a strong vertical impact |
| Heavy wear in certain areas in the middle of the working surface Traces of blocking under full braking | It may be that the brake drum is not round, which contributes to the wheels locking up |
| Scaly or saw-tooth wear of the profile In most cases caused by the destruction of the rubber, which after some time becomes visible from the outside | Overloading the vehicle. Check for rubber tears on the inside of the tire |
| There are rubber tongues on the tread edges | Incorrect installation of the wheel. The wheel is worn on one side. Also check the shock absorbers on the rear suspension |
| Formation of an edge on the rear side of the front wheel profile | Incorrect wheel alignment. Wheel wears on one side. Frequent driving on a road with a convex profile. Fast driving on turns |
| Tears in the base of the tire. At first, only visible from the inside | Driving over high curbs, rails, etc. at high speed |
| One-sided wear profile | Check the wheel alignment |
