Tyre pressure: for a long life of your tyres
The correct tyre pressure makes sure your tyres wear evenly, and you drive comfortably, cleaner and safer. In Europe, an equivalent of 55.6 million tyres is lost every year because of incorrect inflation pressure alone.
Why is the pressure of my tyres so important?
A correct tyre pressure has many benefits.
- Safety: correct inflation pressure provides better control over the vehicle and optimises road holding, braking stability and stopping distances. At low pressures the tyre runs hotter, leading to a weakening of the tyre components and therefore increasing the risk of a blowout.
- Economy: helps minimise tyre wear and fuel consumption. Maintaining the correct pressure is the most cost effective way to save fuel.
- Environment: an under-inflated tyre leads to more fuel consumption and higher CO2 emissions.
- Comfortable: you drive and steer more easily.
How often should I have the pressure checked?
Ideally, you should do this every three-four weeks when the tyres are cold. You should do this when your tyres are cold because the pressure automatically increases when the tyre is hot so you won’t get a correct reading. You should especially check tyres before a long distance trip. Caravans and motor homes should be especially checked before taking on holiday as they may have lost pressure while laid up for the winter.
What happens when my tyres are overinflated?
It will be harder for your tyres to absorb shocks and so the ride will be much harsher and handling performance will be reduced as there will be less contact with the road. Overinflated tyres are more likely to be damaged when driving through a pothole or climbing a curb. It will also cause the centre of your tyres to wear much faster.
What happens when my tyres are underinflated?
Internal heat will build up, weakening the casing and causing damage. The shoulder of the tyre will wear much faster. Driving becomes harder as you have less control and the steering is much heavier.
How do I know what the tyre pressure should be?
It’s not the tyre that defines the pressure but your car. The vehicles tyre pressure is often to be found on a sticker inside the fuel cap door, inside the driver’s door and always in the vehicle. If you have any questions, just ask your First Stop specialist.
Keep in mind that a heavy load requires higher pressure. Again this information should be found in the vehicle manual. Ask your First Stop specialist for advice.
What is nitrogening?
Filling in you tyres with nitrogen is different from normal air because its molecules are bigger making it harder for them to escape. Nitrogen offers you many benefits:
- Safety: the tyre remains constant and there is less risk of a blowout.
- Cost: keeping the correct pressure for longer with nitrogen means you achieve a long tyre life. Furthermore, they will have an optimal rolling resistance therefore maintain the fuel consumption.
