Checking tyre pressure

Correct tyre pressure helps to improve driving stability, saves fuel and extends the service life of the tyres.

Tyre pressure decreases over time, this is a natural phenomenon. Tyre pressure also varies depending on ambient temperature. Driving on tyres with tyre pressure that is too low could result in the tyres overheating and being damaged. Tyre pressure affects travelling comfort, road noise and driving characteristics.

Check the tyre pressures monthly. Use the tyre pressure recommended for cold tyres in order to achieve optimal tyre performance and optimal wear. Tyre pressure that is too low or too high may cause uneven wear on the tyres.

Предупреждение

  • Tyre pressure that is too low is the most common cause of tyre failure and may result in serious cracks in the tyre, the tread loosening or the tyre exploding, with unexpected loss of control of the car and increased risk of personal injury.
  • Tyres with pressure that is too low reduce the load capacity of the car.

Cold tyres

The tyre pressure must be checked when the tyres are cold.

Tyres are considered cold when they have the same temperature as the surrounding air.

This temperature is normally reached when the car has been parked for at least three hours.

After having driven approximately 1.6 km (1 mile) these tyres are considered as warm. If you have to drive further than this to inflate the tyres, first check and record the tyre pressure and inflate to a suitable tyre pressure when you arrive at the pump.

When the outside temperature changes, the tyre pressure also changes. A decrease in temperature of 10 degrees causes the tyre pressure to decrease 1 psi (7 kPa). Check the tyre pressure regularly and adjust to the correct pressure, which is specified on the car's tyre information plate or certification label.

If you check the tyre pressure when the tyres are warm then you must never release any air. The tyres are warm due to driving and it is normal for the pressure to increase above the recommended pressure for cold tyres. A warm tyre with tyre pressure equal to or below the recommendation for cold tyres may have a pressure that is far too low.
