What is the recommended tyre pressure for my car?

Checking your tyre pressure is simple and inexpensive. It is important to stick to your manufacturer’s recommended tyre pressure range to avoid overinflation or underinflation. 

• Overinflation can lead to premature tyre wear in the centre of the tread. 

• Underinflation can lead to premature tyre wear in the shoulder area and reduces the grip qualities. 

The pressure has been optimally defined by the manufacturer for the vehicle/tyre combination. Your vehicle has gone through numerous tests to ensure your safety. This is why it is imperative to consult the recommended tyre pressure provided by your vehicle manufacturer. It is generally indicated: 

• on a sticker on your driver's side door,

• in the fuel filler flap,

• or in the vehicle manual.
  

The recommended tyre pressure for your front and rear tyres may not be the same. It is therefore important to know the difference between each type of pressure.

• Normalized pressure: this is the standard pressure 

• Loaded pressure: to be adopted when the vehicle is particularly loaded, for example when going on holiday 

Tyre pressure is often indicated in pounds per square inch (PSI), kilopascal (kPa), and bar (1 kPa = 0.01 bar and 1 bar = 14.50 PSI). It is important to note that pressure for tyres may vary depending on your vehicle and tyres.

The manufacturer's recommendations are essential for your safety and you should refer to them whenever you check the pressure of your tyres. Otherwise their performance may be reduced, especially in the following cases:

Endurance

Driving on underinflated tyres causes deterioration of the overall tyre structure which can lead to dislocation and/or bursting.

Aquaplaning

If your tyre pressure is incorrect, there is a sharp increase in the risk of aquaplaning. 

Braking

A difference of 1 bar or 14 PSI from the vehicle manufacturer's recommended tyre pressure can increase the braking distance on wet roads by 11 metres. 

Fuel Consumption

Tyres underinflated by 14 PSI have increased rolling resistance, which increases fuel consumption by 1 full tank of fuel per year. 

A tyre inflated to the recommended tyre pressure improves safety, is more economical in use, and better for the environment. 

Regular tyre pressure check is necessary since tyres often lose 0.07 bars per month from the naturally-occurred osmosis

Check your car if it’s equipped with a TPMS (Tyre Pressure Monitoring System) that alerts you when your tyre pressure falls beneath 25% of the manufacturer’s recommended tyre pressure. However, we suggest that you do not wait for this signal to worry about the correct pressure of your tyres.
