How to check your tyre pressure at a petrol station

It is important to look after your tyres as they are an essential part of your vehicle's safety. Your tyres affect your vehicle's braking performance, grip on the road and overall fuel economy. Therefore, it is essential that you maintain them well and keep them properly inflated. Read on to find out how to check your tyre pressure at a petrol station, whilst on the go.

What is tyre pressure?

The air inside a tyre is what creates pressure. The less air there is inside it, the less pressure there is and this means that there is more rubber in direct contact with the road. Not only can this wear your tyres down faster but this can also affect the grip and handling of your vehicle. Driving with under-inflated tyres also increases fuel consumption as your engine will have to work harder to overcome the drag and resistance of your tyres. Over time, the air within your tyres will escape, so it is vital that you check them regularly and top up when needed.

How to find the correct tyre pressure for your car

Check the size of your vehicle's tyres

Generally speaking, a car’s tyres should be the same size all round, with the except of some high performances vehicles. You can check the size of your tyres by checking the side wall. There should be a sequence of numbers and letters which indicate the size of the tyres. For example, the sequence may look like this: 195/55 R16.

Find the correct tyre pressure for your vehicle

Once you know the size of the vehicles tyres, you will need to find out the correct air pressure to be used for them. This can be found in your vehicle’s handbook or user manual. Some vehicles may also have a sticker located within the door frame or fuel filler, which will list the correct tyre pressure for your car. The sticker should display a measurement for normal loads and another measurement for increased loads.

When towing or driving with an increased load, it is important to remember that your tyre pressure will need to be inflated to a higher pressure than you would normally use. This will be dependent on the size of the load you are carrying. Again, this information can be found in the vehicle handbook.

How to check your tyre pressure at a petrol station

  • Most petrol stations and garages will have an air compressor.
  • In order to avoid an incorrect reading, it is recommended that you check your tyre pressure when your tyres are cold. Before you begin driving or sometime after you have stopped driving, for example.
  • To check your tyre pressure, first remove the screw caps from the tyre valve.
  • Then, push the tyre pressure gauge onto the end of the valve. There will usually be a lever to lock the gauge in place. Remember to release this before trying to remove the gauge from the valve.
  • Check the reading on the analogue or digital display.
  • If the reading shows that the air pressure is below the recommended setting for your vehicle, add more air until you have reached the correct pressure. If the reading shows that your tyres are overinflated, simply remove the amount of air needed for your tyres to reach the correct pressure. This can usually be done by releasing the locking lever.
  • Repeat this process for each tyre (including your spare, if you have one!)
  • Once you have finished, replace the valve caps.
