2.5.4.6. Check of drawing of a protector of a tire (tire)
GENERAL INFORMATION


Tires of the balanced wheels wear out approximately evenly on all racetrack of a protector at diligent observance of the ordered pressure of inflating and at the correct installation of provision of wheels and normal functioning of shock-absorbers. At non-uniform wear of tires see technical diagnosing of malfunctions in the corresponding chapter. It is impossible to make a certain conclusion about durability of tire products as term of their service depends on various factors:

 – surfaces of a road cloth;
 – pressure of air in beefy tires;
 – movement mode;
 – weather (weather conditions).

First of all, at a sports mode of movement, sharp dispersal and strong braking of the tire are exposed to fast wear.

Prevention

Bodies of traffic police demand, that tires wore out only to depth of flutes of protektorny drawing in 1,6 mm, namely, flutes of protektorny drawing should have on all racetrack of a protector depth not less than 1,6 mm. However for the purpose of safety we recommend to replace tires already at height of drawing of a protector not less than 2 mm.

If the height of drawing of a protector comes nearer to expected admissible depth of flutes of protektorny drawing i.e. if located in any point of a circle of the tire the wear indicator any more does not fix protektorny drawing, tires should be replaced.
Prevention

M+S – tires of cars for driving on dirty and snow-covered roads with special drawing of a protector have sufficient impact on dirt and snow only if their protektorny drawing still has depth not less than 4 mm.

Investigate the tire on existence of places of cuts and by means of a small screw-driver establish depth of cuts. If cuts reach a tire framework, because of getting water the steel cord of the radial tire is exposed to corrosion. Thanks to it under known conditions the racetrack of a protector and the tire comes off a framework is broken off. Therefore with a view of safety replace the tire at deep cuts in protector drawing.
