Correct tyre pressure can help to extend the life of your tyre, improve vehicle safety and maintain fuel efficiency. Pressure is measured by calculating the amount of air that has been pumped into the inner lining of your tyre in pounds force(PSI) or BAR pressure.
The manufacturer of your vehicle specifies the suitable pressure, usually in your handbook, or on a sticker somewhere around the car. It is your responsibility to make sure that the pressure is checked and corrected regularly.
Maintaining the correct tyre pressre is important for the following reasons;
- Safety - underinflated tyres can overheat, and over inflated tyres can lead to poor road handling
- Economy - If your tyres are over or under inflated, your tyres will suffer more damage and will need to be replaced more regularly. Under inflated tyres have increased rolling resistance and will require more fuel to maintain the same speed.
- Environmental impact - Correctly inflated tyres help to maintain optimum fuel efficiency, which in turn creates less Co2 emissions from your car.
Always check the tyre pressure with a tyre pressure gauge when your tyres are cold. Finally, if you are using your vehicle to carry additional load or weight, always consult your vehicle handbook for the correct loaded tyre pressure.
