Checking tire tread (tire)
Tires balanced wheels wear evenly around the entire tread in good faith compliance with the prescribed inflation pressure and correct installation position of the wheels and the normal functioning of the shock absorbers. If you see uneven tire wear. Technical diagnostics of faults in the relevant chapter. You can not make a definite conclusion about the durability of tire products, since their life depends on various factors: - The surface of the roadway;
- Air pressure in the tire inflated;
- Driving mode;
- Weather (weather conditions). First of all, when the sport driving mode, sudden acceleration and sudden braking the tires are subjected to rapid wear.
A warning  STSI bodies require only a worn tire to the groove depth of the tread surface is 1.6 mm, namely, the grooves of the tread pattern should across the tread have a depth of not less than 1.6 mm. However, for safety reasons we recommend to replace the tires already at the tread depth of at least 2 mm.
If the height of the tread approaches the assumed allowable depth of the grooves of the tread pattern, t. E. If located anywhere in the tire circumferential wear indicator no longer captures the tread pattern, the tire must be replaced.
A warning M + S - car tires for driving on muddy and snow-covered roads with a special tread pattern provide sufficient impact on the mud and snow only if their tread pattern still has a depth of at least 4 mm. Explore the tire on the availability of cuts and using a small screwdriver, set the depth of the cuts. If the cuts reach the tire carcass, is due to penetrating water corrodes the steel cord radial tires. Because of this, under certain conditions, separated from the carcass and tread tire bursting. Therefore, for safety reasons, replace the tire with deep cuts in the tread pattern.
