dfe5d7b3 Service life of tires


Service life of tires depends generally on the following factors:

Pressure in tires


The wrong pressure in tires results in the increased wear of tires and negatively affects coupling of tires with darling conducting to loss of controllability of the car and traumas.

The wrong pressure in tires can lead to that the tire can suddenly go down that will lead to failure and traumas.

Check pressure in tires twice a month and especially before distant trips. Do not forget to check also pressure in a spare wheel. Always check pressure in tires when tires cold. When tires warm, pressure will be higher. Do not lower pressure in warm tires.

Use the exact sensor for pressure measurement in tires. Do not pump up the tire to bigger pressure, than it is specified on lateral face of the tire. Pressure in the cold tire designates that the car before check stood within at least 3 hours or passed no more than 1,5 km.

Always check pressure in the tire of a spare wheel at pressure check in tires.

Demanded pressure in cold tires is given on a sticker pasted in a luggage carrier on the back panel.

For cars with big decorative caps: on gates extension pieces instead of dustproof caps are established.

At pressure check in tires, do not remove extension pieces of gates.

Style of driving

Abrupt turns, fast dispersal and sharp braking increase speed of wear of tires.

Balancing of wheels

Wheels on new the car precisely отбалансированы. After a certain period of operation, however, the various reasons lead to disbalance of wheels. It can be appreciable as vibration at turns of a steering wheel.

As driving with the debalanced wheels results in fast wear of the mechanism of a steering, a suspension bracket and tires, wheels it is necessary отбалансировать anew. It is necessary to carry out balancing of wheels each time after replacement of the tire or its repair.

Shift of tires

If forward tires wore out more than back, we recommend, that you traded places lobbies and back wheels how is shown on an illustration.

Having performed this operation, you will provide to all the tires almost equal service life.

After shift of wheels, adjust pressure in tires and tighten bolts of fastening of wheels diagonalno to 110 N of m.

Tires always should remain on one party of the car.

Only if on tires there are unusual wear tracks, such, for example, as on edge of the tire, them it is necessary to replace wear diagonalno.

Wear of tires


The tires established on Aуди cars by production, have the indicators of wear provided by a design. They are soldered in on a bottom of flutes of a protector and become visible as a strip in thickness about 12 mm when drawing of a protector will wear out so that depth of flutes becomes equal 1.6 mm. Depending on what production of the tire, on them are available from 6 to 8 indicators of wear located evenly on a circles of the tire. Marks in a lateral surface of tires (for example, the letters "TWI" or a triangle) designate location of indicators of wear.
