Table 3. Permissible tire and wheel sizes and air pressure in tires
* Speed indices: T - up to 190 km/h, H - up to 210 km/h, V - up to 240 km/h. Load indexes: 82 - 475 kg.
** Rim offset (ET) - distance from the mating plane of the disk to the middle of the rim.
*** Partial load - no more than 3 adults in a car without cargo in the trunk.
**** Full load - more than 3 adults or 3 adults and a load of 50 kg in the trunk. Winter tires are allowed (M+S) of the above dimensions and the Q index with the corresponding maximum vehicle speed limit (up to 160 km/h).
If the pressure drops with a good spool, then it is necessary to repair the tire.
In order to avoid damage to the sealing layer of the tire, dismantle and mount it using a special device or on SSSS certified by the manufacturer. In order not to disturb the balance of the wheel, make a mark with chalk on the tire opposite the valve before disassembly, and during installation, install the tire according to this mark.
After installing new tires, be sure to balance the wheels on the SSSS certified by the manufacturer.
To ensure even tire wear, rotate the wheels as shown in fig. 52 according to the instructions in the service book.
When operating the vehicle, avoid rubbing the wheels against the curbs and driving fast on roads with broken surfaces (potholes, potholes, etc.), since damage to the wheel rim can cause not only its imbalance, but also the loss of tightness of tubeless tires. If vibrations appear during the movement, check the wheel balance on the SSSS certified by the manufacturer.
Warning! It is forbidden to raise the car with the help of a jack with the wheels not braked and to be under the car raised by the jack.
The base of the jack is designed to work on hard surfaces and soils. To prevent the jack from falling through on eroded, loose soil, snow, loose sand, etc. it is recommended to put a piece of board, plywood or other hard material at least 250x250 mm in size.
Tire pressure monitoring system
The car is equipped with a tire pressure monitoring system (TPMS).
The system consists of four sensors installed in the tires, a control unit that is a signal receiver, and a signaling device located in the instrument cluster. Replacement of sensors and training of the system is carried out only at authorized SSSS.
Illumination of the yellow signaling device (!) tire pressure monitoring system indicates a decrease in pressure in one or more tires. Continued driving with low tire pressure can cause overheating and mechanical failure of the tires. Under-inflated tires also increase fuel consumption, shorten tire life, and can affect vehicle handling and stopping distance.
If the indicator lights up, you must stop the car as soon as possible, check the condition of the tires and bring the level of pressure in them to normal.
Please note that the use of TPMS does not mean that the tires do not need to be properly maintained or maintained at the correct pressure, even if the reduction in pressure level is not enough to trigger the TPMS low tire pressure warning light.
A signaling device is also used to notify of a malfunction of the TPMS system (!).
When the system detects a fault, the indicator flashes 5 times at a frequency of 1 Hz, then remains on continuously.
The TPMS malfunction alarm is reset each time the ignition is turned on, as long as the malfunction exists. When the malfunction indicator light is on, the system may not be able to detect or signal low tire pressure as intended. A malfunctioning TPMS system can be caused by a variety of reasons, including installing or changing tires or wheels.
Always check the TPMS malfunction indicator light after changing or swapping one or more tires or wheels to ensure that the TPMS is working.
