1. The tyres are equipped with built-in tread wear indicator strips which become exposed when the tread depth drops to 1.6 mm, after which the tyres are considered worn out. This value represents the minimum permissible tread depth; in most cases, it is recommended to replace tires with a tread depth of 2 mm or less. Tread depth can also be determined using a simple and inexpensive device known as a tread depth gauge.
2. Pay attention to any unusual wear on the treads. Tread defects such as cavities, bulges, flattening and more severe wear on one side indicate a violation of the front wheel alignment angles and/or wheel balancing. If any of the listed defects are detected, you should contact a tire repair shop to have them corrected.
To determine tire wear, use a tread depth gauge - they are sold at auto accessory stores and service stations and are very inexpensive.
3a. Check the tire carefully for cuts, punctures, and stuck nails or tacks. Sometimes after a tire is punctured with a nail, it still holds pressure for some time or deflates very slowly. If you suspect that you have such a "slow puncture", first check the tightness of the inflation valve nipple.
3b. Then inspect the tread for any foreign objects stuck in it or previously repaired punctures that have started to leak air again. If you suspect that there is a puncture, you can verify its presence by wetting the suspected area with soapy water. If there is a leak, the solution will begin to bubble. If the puncture is not too big, the tire can usually be repaired at any tire shop.
4. Carefully inspect the inside sidewalls of the tires for signs of brake fluid leakage. If any are present, have the brake system checked immediately.
5. Maintaining proper tire pressure increases tire life, helps save fuel and improves overall ride quality. To check the pressure, a special pressure gauge is required.
Recommendations. Always keep an accurate pressure gauge in your glove compartment. Pressure gauges built into air hose nozzles at service stations are often inaccurate.
6. Always check tire pressure when tires are cold (i.e. before traveling by car). Checking the pressure on warm or hot tires will result in an overestimation of the pressure gauge reading due to thermal expansion of the tires. In this case, you should never release the pressure, because after the tire cools down, it will be below normal.
7. Unscrew the protective cap from the inflation valve protruding from the wheel rim or hub cap, then press the pressure gauge nozzle firmly onto the valve. Read the instrument readings and compare them with those recommended in the Specifications. Be sure to replace the protective cap to prevent dirt and moisture from entering the valve mechanism. Check the pressure in all four tires and inflate them to the recommended pressure if necessary.
8. Don't forget to maintain the required pressure in the spare tire.
Examples of typical tire tread wear
Lateral wear
Insufficient pressure (wear on both sides)
Underinflation of the tyre causes it to overheat while driving due to excessive deflection, resulting in the tread not being pressed sufficiently against the road surface. This results in loss of traction and excessive tread wear, not to mention the risk of tyre failure due to overheating.
1. Check and adjust pressure.
Incorrect wheel alignment (wear on one side)
1. Repair or replace suspension parts.
Too sharp turns
Slow down!
Central wear
Excessive pressure
Overinflation of a tire results in accelerated wear of the center tread, reduced traction, harsher ride, and an increased risk of fatal tire damage.
1. Check and adjust pressure.
2. If you had to inflate your tires to the pressure specified for this purpose in order to transport heavy loads, Specifications pressure values, do not forget to release it after this when switching to normal operating mode.
Uneven wear
Front tires may wear unevenly due to improper wheel alignment. Most tire shops can check and adjust the alignment angles for a reasonable fee.
1. Incorrect camber or runout. Repair or replace suspension parts.
2. Suspension defect. Repair or replace suspension parts.
3. The wheels are out of balance. Perform wheel balancing.
4. Front wheel alignment is incorrectly set. Adjust the front wheel alignment angles.
Note: Frayed edges of the tread pattern, which is a sign of wear, are best detected by touch.
