No matter the car you own it is vital to keep certain elements in check for safety. Tyre pressure is something you must be certain is absolutely okay for many reasons (which we will explore). If you are somebody who wonders, ‘What is the tyre pressure on my car?’ or ‘How do I sort it?’, then reading this blog could give you the baseline help you need. In need of more than that? Get in touch with our team today, and we can take a look at your tyres!

Why Does Tyre Pressure Matter?

Tyre pressure refers to the amount of air inside your tyres, measured in PSI (pounds per square inch). Every vehicle has a recommended tyre pressure set by the manufacturer, designed to keep the car performing safely and efficiently.

 

And what is the importance of tyre pressure? Well, without it sorted, it can hugely affect your driving performance. When driving you rely on braking, comfort and grip – and all of those can be altered by your pressure.

How To Check Your Car Tyre Pressure

  1. Find the correct tyre pressure
    Start by checking your car’s recommended tyre pressure. This is usually found:

  • Inside the driver’s door frame

  • Inside the fuel filler cap

  • In the vehicle handbook

In the UK, tyre pressure is typically shown in PSI (pounds per square inch), and sometimes BAR as well.

  1. Check tyres when they’re cold
    Tyre pressure should be checked when the tyres are cold, ideally before driving or after the car has been parked for a few hours. Driving heats the tyres and can give an inaccurate reading.

  2. Use a tyre pressure gauge or air pump
    You can use:
  • A digital or manual tyre pressure gauge at home

  • A petrol station air pump

Remove the valve cap from the tyre, press the gauge firmly onto the valve, and read the pressure.

  1. Adjust the pressure if needed
    If the pressure is too low, add air until it reaches the recommended PSI.
    If it’s too high, release a small amount of air and recheck.

  2. Don’t forget all tyres
    Check all four tyres, and the spare if your vehicle has one. Front and rear tyres often have different recommended pressures.

  3. Replace the valve caps
    Once finished, refit the valve caps to keep dirt and moisture out.

Keeping your tyre pressure at the correct level helps improve safety, and tyre lifespan. It’s a small check that makes a big difference to how your car performs on the road.

Do You Need Professionals For This?

Although you can come to us if you are struggling with the process, there are certainly other scenarios where it is best to do so. For example:

 

  • Your tyre pressure keeps dropping

  • The car feels unstable or pulls to one side

  • You’re unsure what pressure your tyres should be

  • You notice uneven tyre wear

  • You’re preparing for a long journey

 

If any of these occur, please contact us so we can check over the vitals. It is not worth the risk leaving your car – they don’t heal by themselves.

What Is The Correct Tyre Pressure For My Car?

There isn’t one correct tyre pressure that applies to every car. The correct tyre pressure for your vehicle is set by the manufacturer and is based on factors such as the car’s weight, size, and handling characteristics.

You can usually find your car’s recommended tyre pressure in one of the following places:

  • Inside the driver’s door frame

  • Inside the fuel filler cap

  • In the vehicle handbook

In the UK, tyre pressure is typically measured in PSI (pounds per square inch), and some vehicles may also show the pressure in BAR.

It’s also important to note that front and rear tyres often require different pressures. In some cases, the recommended tyre pressure may change if the car is carrying heavy loads or is being driven at sustained motorway speeds.

If you’re unsure which pressure applies to your car or how to read the information, a tyre professional at Longbridge Tyres can check this for you and make sure your tyres are inflated correctly.
