The pressure of a tyre is calculated by the amount of air that’s pumped into the inner lining of the tyre in pounds per square inch (or PSI for short) pressure. Your vehicle manufacturer will specify the suitable pressure for the tyres, but it is your responsibility to make sure the pressure is checked and corrected on a regular basis. We at Swinton Recovery would recommend doing this around every fortnight to ensure you keep optimum tyre pressure.
Tyres can quickly become underinflated (this can obviously vary for each individual driver dependent on how they drive, or how much they are driving daily.) if you do not check them regularly. If a tyre is under inflated the tyres will have uneven contact with the road and will wear alot faster on the in and outer edges. This will also reduce your fuel efficiency and increase your C02 emissions.
Having too much air in a tyre can be just as costly and damaging as having too little. Over inflated tyres have smaller contact with the road and can lead to loss of traction and worsen your breaking distance.
