Wheels and tires

Constantly checking the condition of the tires will allow you to detect intensive wear in a timely manner and eliminate its cause, which will help to avoid more serious consequences.

Check tires for cuts, cracks or other damage. Replace tires that have deep cuts or cracks. Also periodically inspect all tires and remove metal objects and stones stuck in them. Driving on tires with worn tread is very dangerous due to the high risk of skidding or hydroplaning (tire pop-up (s) above the road surface flooded with water). For tires to meet the minimum roadworthiness requirements, the tread depth must be at least 1.6 mm.

Tire tread depth

In the grooves of the tire tread pattern there are "tire wear indicators" 1.6 mm high, located at right angles to the direction of translation of the tire. These indicators range from six to eight (depending on the manufacturer) placed at equal distances around the circumference of the tire. Tire sidewall markers (e.g. letters «TWI» or a pictogram and a triangle) show the location of the tire wear indicators (pic. 1.9).




Tires can be used up to a profile depth of 1.6 mm, that is, the profile grooves must have a depth of at least 1.6 mm over the entire surface of the tire. However, for safety reasons, it is recommended to change tires at a profile depth of 2 mm.

M+S tires have sufficient grip on snow with a profile depth of at least 4 mm.

Tire pressure

Use a tire pressure gauge to check tire pressure monthly, including the spare wheel.

To maintain optimum tire performance, check pressure only when the tires are cold. Under- or over-inflated tires can cause uneven tread wear.

Wheel swap

In order for the tires of the front and rear wheels to wear out at the same time, and it was possible to change the tires as a set, it is necessary to constantly pay attention to the uniformity of their wear and rearrange them in a timely manner. The wheels must be rearranged not diagonally to the car, but in such a way that they retain their original direction rotation (pic. 1.10. 1.11). When rearranging wheels, check for tire wear and damage. Uneven wear is usually caused by incorrect tire pressure, incorrect wheel alignment, imbalance, or sudden braking.

Winter tires

When driving on snow and ice, winter tires are recommended. To ensure the stability of the vehicle in motion, install winter tires of the same size and with the same tread pattern on all four wheels. Winter tires with more than 50% tread wear are not suitable for use as winter tires. Winter tires that do not meet the technical requirements and specifications must not be used.
