Before a long journey or when you check tyre pressure, verify the general condition of your tyres and their level of wear. If they are displaying any one of the symptoms described below, don’t hesitate: change them straight away.

A worn tyre cannot fulfill its function, especially when it comes to holding the road in wet weather. Result: The braking distance on wet roads increases, as do the risks of sideslipping and aquaplaning.

Regular monitoring of your tyres will enable you to know when to change them. Here are some situations which should warn you.

  • The tyre reaches the legal wear limit (tread depth less than 1.6 mm). The wear indicator appears on the tread. As a general rule, a good quality tyre should be changed every 40 000 or 50 000 km, lower quality tyres every 10 000 km. However, the lifespan of a tyre varies considerably. It depends on many factors, the most important being the driving style and the roads covered. You should also know that, for a front-wheel drive, the tyres wear twice as fast at the front as at the rear.

  • The difference between the depth of the main grooves on two tyres fitted to the same axle must not exceed 5 millimetres. This difference in wear between tyres can adversely affect the car's behaviour.
  • The tyre displays abnormal wear. This can occur in several forms: spot wear, asymmetric wear, wear in the centre or wear at the tread shoulders. 
In this case, you should deal with the mechanical problems that have caused this abnormal wear.
  • The tyre is damaged. There are cuts, cracks or deformations which may cause a slow puncture or a burst of a tyre.

  • The tyre does not comply with the manufacturer's recommendations: incorrect dimensions, speed and load ratings not respected, etc.
