The control of a condition of tyres

The similar control is better to make at the lifted car, for example at oil replacement by refuelling.

 PERFORMANCE ORDER

  1. Completely turn each wheel.
  2. You can clean alien bodies of type of small stones from cuts of a profile of a protector by means of a narrow screw-driver, without having damaged thus the tyre.
  3. According to instructions, since 1992 depth of a profile of tyres should make on all width a minimum of 1,6 mm.
  4. For safety reasons you should change tyres already at deterioration to 3 mm because wide tyres Audi 80 "float" on a wet road surfacing earlier, than narrower tyre covers of old automodels.
  5. For the deterioration control eminences serve in flutes of drawing of the protector, passing through regular intervals perpendicularly to a protector racetrack. They are designated on sidewallsе tyre covers by letters «TWI» (tread wear indicator – an indicator of deterioration of a profile).
  6. If these eminences are flush with flutes of drawing of a profile, means, the residual profile makes 1,6 mm and the tyre it is necessary to change immediately.
  7. By the form deterioration of a profile you can understand much, the description in following section.

Picture of deterioration of the tyre

  • The forward tyres which were worn more out on an outer side, are not something unusual in Audi 80. The reason is the raised loading of this area of a racetrack at passage of turns.
  • Односторонне the worn out tyres, however, can specify and in wrong adjustment of corners of installation of wheels, especially if only one tyre is worn out thus.
  • Strong deterioration in the middle of the tyre specifies in the overestimated pressure. This effect is swept especially up on back wheels. Or you go by high speed because of what the racetrack is brief much.
  • If on both outer sides of the tyre the profile is worn out more strongly, than in the middle, means, pressure of air in tyres was long time too low.
  • Non-uniform, stains, deterioration of a profile of the tyre specifies in the defective shock-absorber.
  • If non-uniform deterioration appears only on certain places, means, a wheel not отбалансировано or the tyre cover skeleton is damaged.
  • The One and only place with strong deterioration of a profile was formed as a result of braking with the blocked wheel, so-called «a brake mark» (only at the models which have been not equipped АБС).

 The help: if it is necessary to remove the serviceable wheel balanced on the car – for example, for the control of a condition of brakes before it it is necessary to note position of a nave of a wheel. Otherwise after repeated installation of a wheel balancing will be wrong.
