1.1.34. Check of a state and replacement of tires
Spare wheel The indicator of wear which becomes visible is built in tires of the car when depth of a protector becomes less than 1,6 mm. If the indicator of wear is looked through on two and more nearby paths of a protector, then the tire should be replaced. The stronger the protector is worn-out, the possibility of a drift is higher. On winter tires the extreme residual depth of a protector makes 4 mm. Periodically check a condition of tires, existence for them such damages as cuts, peeling of a protector, crack. At detection of the specified damages consult in service of car service on a possibility of further operation of the tire. Tires with the term of operation or storage have to be checked more than 6 years by the expert, even in the absence of external damages. It is necessary in connection with deterioration in properties of rubber because of aging. Replacement of tires When replacing install tires completely identical on the type and a design replaced. Otherwise driving worsens, the accuracy of indications of a speedometer and the counter of the passable way is broken, the clearance and a free wheeling of a wheel in a niche of a body differ from norm. Prevention
It is not allowed to install the tires which were in the use. The manufacturer recommends to change at the same time tires a set at least for one axis. After replacement of the tire the wheel should be balanced. In use tires it is necessary to check periodically their balancing because of unevenness of wear. When replacing tubeless tires the gate for a rating should be replaced new. |
