August 19, 2014Tyre Pressure Tips
Having the right tyre pressure is essential for safer driving. Under-inflated tyres affect vehicle handling and road grip. Having tyres at the wrong pressure could cause irregular or unpredictable vehicle behaviour; skidding for example. Incorrectly inflated tyres are under excess stress and as a result are much more likely to suffer from a dangerous blowout, especially at high-speed on motorway journeys.
Keeping your tyres at their optimum pressure will help prolong their life of your tyres, and your running costs will also be reduced. Under-inflated tyres require a more force to make them turn, which requires your vehicle to use more fuel. As a result tyres which are not set to their correct pressure will wear out more quickly. Tyres that are inflated to the correct pressure help to reduce your car’s CO2 emissions because you are using less fuel.
To ensure you benefit from lower fuel bills, longer tyre life, increased safety and reduced emissions, make sure your tyre pressure checks become a regular part of your car care regime. We recommend a check once a month and before a long journey.
The difference between BAR Pressure and PSI Pressure
Bar or PSI are the two different measurements to record tyre pressure. 1bar is equal to approx 14.5 psi, this equates to the average atmospheric pressure at sea level. You can convert a bar pressure measurement into a psi pressure measurement using a tyre pressure converter.
Tyre Pressure Tips:
- Check your tyre pressure regularly. We recommend a monthly check, the same as you might replace your screen fluid for example. Definitely be sure to check your tyre pressure before longer trips and when you vary the vehicle’s usual load.
- Don’t check your tyres after you have been out driving. The get an accurate reading the tyres must be cold when you carry out the check.
- Check your vehicle manual to ensure you have the right pressure reading. This may also be located on the driver’s door ledge or inside the petrol cap.
- Follow the instructions provided in your vehicle’s manual to change the pressures for when the vehicle is fully loaded (for instance, when you are packed and ready to go on your family holiday).
- Locate the tyre valve. Every tyre has a valve for inserting and expelling air. This is covered by a dust cap and is removed by twisting anti-clockwise. Keep the cap in a safe place as you fill your tyres with air.
- Use a dependable gauge to measure your pressure. Most service stations and garages have air pumps for your use. These should be regularly maintained and also can help with automatic insertion of air once the pressure required is established.
- Remember to examine all of your tyres including the spare – you may need this one in an emergency and it will need to be fully inflated too!
- If you are towing any vehicles – for example, a trailer/caravan/horsebox, don’t forget to check these tyres too.
- As well as doing your pressure check make sure you give your tyres a visual check over. Are they in good condition? Can you see any obvious damage? Look out in particular for tread wear and tear or problems such as cuts, bumps or bulges. All indicate potentially serious issues.
- Remember: pressure decreases more rapidly in warmer weather, so make sure you check tyres more frequently during the summer months.
