| Sign of malfunction | Possible causes/solutions |
| 1 | 2 |
| Uneven and rapid wear | Uneven and rapid tread wear can be caused by various reasons, such as: too low or too high air pressure in the tire, increased wheel rotation torque, frequent use of the braking system, or incorrect wheel alignment angles. When adjusting the wheel alignment angles due to rapid or uneven tire wear, it is necessary to set the minimum wheel alignment permissible according to the technical specifications |
| It is recommended to rotate the wheels in the following cases: the wear of the front wheels differs from the rear ones; uneven lateral wear of the tread on any wheel; uneven wear of the front wheels; uneven wear of the rear wheels | |
| It is recommended to check the wheel alignment angles in the following cases: uneven wear of the front wheels; uneven lateral wear of the tread on any wheel; the front wheel treads have wear zones with one-sided sharp ridges along the tread pattern or along the edges of the tread blocks | |
| Lateral vibrations of the body | Lateral vibrations of the front and/or rear part of the body are caused by the uneven position of the steel belt of radial tires relative to the plane of symmetry of the tire. Another reason could be increased axial runout of the wheel or tire |
| Lateral vibrations are most pronounced at low vehicle speeds, ranging from 8 to 48 km/h. They can also impair ride comfort at higher speeds, ranging from 80 to 120 km/h | |
| Lateral vibrations of the body (continuation) | The vehicle may be subjected to a road test to determine the location of the tire that causes lateral body vibration: front and rear. If a faulty tire is installed at the rear, the driver's seat will feel periodic lateral jolts |
| Lateral vibrations are more pronounced if the faulty tire is on one of the front wheels. In this case, longitudinal vibrations of the sheet metal body panels become noticeable and it seems to the driver that the vertical axis of the car's vibrations passes through his place | |
| In case of low intensity lateral vibrations, when it is not possible to determine the location of the faulty wheel, it is necessary to do the following: test drive the car to determine the location of the faulty wheel: front or rear; replace the car's wheels with similar, but known to be in good working order (for example, dismantled from the same vehicle), it is recommended to start by replacing the rear wheels; conduct a test drive of the vehicle. If there are no signs of a malfunction and the vehicle's performance has improved, you should first return one of the removed wheels to the vehicle, and then the other. This will help identify the faulty wheel. If lateral vibrations continue after replacing the rear wheels, it is necessary to replace them with known good front wheels. After this, you need to return one of the removed wheels to the car and thus identify the faulty one | |
| The car pulls to the side | When pulling away, the vehicle tends to move in a lateral direction when driving on a flat, horizontal road (without transverse slope of the road surface) and with the steering wheel free |
| Car drift is usually caused by the following reasons: tire design features; uneven braking forces on the sides of the vehicle; wheel alignment error | |
| Violation of manufacturing technology or certain design features of tires may cause the vehicle to drift. For example, the displacement of the steel belt from the equatorial plane of a radial tire, even with rectilinear wheel movement, leads to the emergence of a lateral force that causes rolling with slip. The tire tends to move like a cone | |
| To determine the cause of the vehicle's drift, diagnostics should be carried out in accordance with the recommended algorithm |
Caution: The rear wheels cannot cause the vehicle to pull away.
