1TYRE WEAR CHECKAll OKProblems metOperation

Check the wear of the tyres. In particular:

  • Wear on the outside;
  • Wear on the inside;
  • Wear on the tyre wall;
  • Tread wear
End of diagnosisEven wear on both sides: tyre inflation pressure lowRestore the correct tyre inflation pressure If necessary, replace the tyres Op. 4450B24
Wear on one side (outside or inside)Continue to Step 2
Wear on the tyre wallsThe problem is due to the customer''s driving style which is too ''sporty'': if necessary, replace the tyres Op. 4450B24
Wear in the centre of the tread: inflation pressure too highRestore the correct tyre inflation pressure If necessary, replace the tyres Op. 4450B24
Even wear on the surface of the tread: quality of the mixtureReplace the tyres Op. 4450B24
Wear of the tread in patches: locking of the wheels during brakingReplace the tyres Op. 4450B24
