1. The minimum allowable tread depth is 1.6mm. You can assess the degree of tread wear using a special inexpensive device (see accompanying illustration) - ask in car accessories stores.
2. Pay attention to any signs of uneven tread wear. Such local tread defects, such as cupping, flattening, etc., usually owe their appearance to violations of the front wheel alignment angles or the balance of the latter. To identify and eliminate faults, the car should be driven to a specialized car service workshop or to a service station.

3a. Carefully inspect the tires of all wheels for cuts, punctures, and foreign objects stuck in the grooves of the tread pattern. Sometimes a punctured tire continues to retain air for some time due to the fact that the object that punctured the tire continues to be stuck in it. The reason for the slow deflation of the tire may be a defect in the nipple of the wheel inflation valve - check the condition of the nipple (see accompanying illustration).

3b. Carefully check the protector for the presence of objects stuck in it or for violations of the tightness of the fit of the repair "traffic jams", used to repair small tire punctures. You can easily check for a puncture by wetting the suspected area of the tire surface with a solution of soapy water (see accompanying illustration) - if a puncture occurs, the water will begin to bubble. Minor punctures are easily repaired in tire shops.
4. Carefully inspect the inner walls of the tires of all four wheels for the presence of brake fluid leaks on them. If any are found, immediately check the condition of the relevant brake mechanisms and the hydraulic lines connected to them.
5. Maintaining the required tire inflation pressure will significantly extend the life of the wheels, in addition, it will provide maximum driving comfort and will not reduce the vehicle's controllability. Remember that it is almost impossible to determine the correct tire pressure by eye, especially when it comes to radial tires. It is necessary to keep a suitable pressure gauge on hand at all times - the readings of the booster compressor meters at gas stations and service stations should not be trusted.
6. Check the tire inflation pressure when the tires are cold - it is assumed that the car has not driven more than one mile in the last three hours. Remember that pressure increase by 0.3÷0.6 kgf/cm2 as a result of wheel heating is quite normal.

7. Remove the protective cap from the wheel inflation valve and firmly press the manometer nozzle to the valve outlet by pressing the nipple stem (see accompanying illustration). Read the reading and compare it with the normative data, correct the pressure if necessary.
8. Do not forget to screw the protective cap of the valve back into place to prevent moisture and dirt from entering the nipple. Check the pressure in all tires, including the spare.
Note. The inflation pressure of a compact type spare tire is usually noticeably higher than that of conventional wheels.
