For your own safety and the safety of other road users, please strictly adhere to the following rules.
Factory tires are selected for this car model. Provides optimal comfort and driving safety.
When replacing them, consult with specialists. Incorrectly selected tires or wheels that do not fit your vehicle can cause an accident.
It is better to replace them in pairs or sets, i.e. all four tires at once. Tires must be of the same size, design, made of the same materials and with the same profile pattern.
Tire pressure

Checked on cold tires, including the spare tire, every 14 days, before any more or less long trip.
Do not reduce the pressure increased by heating the tires. Otherwise, it may be lowered below the norm.
Exceeding or not complying with the permissible standards negatively affects traffic safety, the driving performance of the car, reduces the feeling of comfort, increases fuel consumption, and increases tire wear.
Reducing the pressure below the permissible level can lead to overheating of the tire, its damage from the inside, and when driving at high speed, as a consequence - to peeling off of the treads. The tire may even burst.
Condition of tires and wheels
Wheels hitting sharp objects and curbs can lead to hidden defects in tires and wheels. These defects can cause tires to burst, especially when driving at high speeds. Therefore, curbs should be crossed at right angles whenever possible. When parking a car, the tires of the wheels should not be pressed against the curbs.

Check your tires regularly for damage (foreign bodies stuck in the treads, punctures, cuts, scratches, bulges on the sides). Damaged tires may burst. The condition of the disks is checked in the same way. If they are damaged or the rubber is slightly worn, contact a service station.
Also systematically check the thickness of the profile pattern of the treads. If the wear on the front tires is more noticeable than the rear ones, swap them. Wheels with the best treads are installed at the front.

For safety reasons, it is recommended to change tires when the tread pattern thickness is 2-3 mm (on winter tires - up to 4 mm). The maximum permissible wear level (1.6 mm) is considered to be reached when the wear indicator on the tire profile begins to be visible. These cast indicators are evenly distributed around the entire perimeter of the tread. Their locations are indicated by marks on the sidewall of the tires.

General recommendations
Remember, the more wear on your tires, the higher the risk of aquaplaning (wheels coming off the road surface while driving).
Tires are subject to aging even if they are used little or not at all. After 6 years, the spare wheel should only be used as a replacement in the event of an accident and only for driving at low speeds.
Never use tires with expired or unknown service life.
Winter tires

The car is equipped with M+S type tires, suitable for use in all weather conditions (all-weather).
Anti-skid chains

On cars with steel and aluminum wheels, anti-skid chains can only be installed on the rear wheels and must be firmly tensioned.
Use only recommended thin chains with a thickness of no more than 15 mm.
Anti-skid chains are used at speeds up to 50 km/h and only on roads covered with deep snow. In all other cases, they wear out quickly and may tear.
