Tyre Pressure Importance

Checking Tyre Pressure

The most important car tyre care tip is for maintaining the correct air pressure. Tyres constantly lose pressure due to a combination of temperature fluctuation and permeation (where the air inside the tyre slowly passes through the rubber). Pressure loss varies from 1-3 psi (pound per square inch) per month depending on temperature variation and the type of tyres you have fitted to your vehicle.

To avoid excess pressure loss, tyres should be checked when they’re cold and around once every two weeks and especially before a long drive. The correct tyre pressures can be found on the tyre pressure plate located inside the driver’s door. On some vehicles, you may find a sticker inside the fuel filler cap. Manufacturers recommended tyre pressure may also be found in the car owners manual.

Under-inflated Tyres

Under-inflated tyres can result in:

• Excess wear around the shoulders of the tyre
• Increase in fuel consumption
• Vehicle instability
• Reduced handling capability
• Increased tyre heat
• Increased risk of a tyre blowout
• Increased risk of tyre damage

Over-Inflated Tyres

Over-inflated tyres can result in:

• Excess wear around the centre of the tyre
• Vehicle instability
• Reduced handling capability due to less road traction
• Increased risk of a tyre blowout
• Increased risk of tyre damage
