Tyre Pressures

Making sure that your tyres are kept at the correct pressures is vital for vehicle safety, as driving on tyres that are inflated to the wrong pressures will provide less grip and seriously decrease handling abilities, as well as wearing quicker.


Why Do I Need to Check my Tyre Pressures?

There are a range of potential dangers related to driving on tyres that are over or under inflated:

Under Inflated Tyres


Over Inflated Tyres


How Often Should I Check my Tyre Pressures?

PTA Garage Services recommend that you check your tyre pressures every four weeks and before you make any long journeys.

This is because air will escape from your tyres when you drive and in turn will lower your tyre pressure. If you don’t regularly check it, you could find yourself driving on under inflated tyres.


What is my Correct Tyre Pressure?

Before you check your tyre pressures, you will need to find the recommended tyre pressure for your vehicle. This can be found in the vehicle handbook or on a label attached to the edge of the driver door or inside the fuel cap flap.

Be aware that there may be different tyre pressure specifications for front and rear tyres and if you are carrying a heavy load you will need to adjust your pressures accordingly. So always check the recommended tyre pressures if you are carrying extra passengers or a full load.


How Can I Check my Tyre Pressures?

You can check your tyre pressures easily using a tyre pressure gauge, which are available for free or a small cost at most petrol stations.

Then you should remove the dust cap from your tyre and attach the pressure gauge. Your tyre pressure will then be displayed. If your tyre is underinflated, use the facilities at the service station to fill it to the correct amount.

Alternatively, if your tyres are over inflated, you should allow some air to escape before rechecking. When you have finished, make sure that you put the dust cap back on tightly.


If you have any queries regarding tyre pressure or feel uncomfortable checking it yourself contact your local PTA Garage Services branch where our trained specialists will be happy to help.

As well as frequently checking your tyre pressure, you should keep yourself safe on the road by monitoring your tread depth and frequently inspecting the condition of your tyres.
