The centre of a low-pressure tyre does not make as much contact with the road as the outside edges, meaning at the edges of your tyre wear out faster, reducing the lifespan of your tyre and making your car more prone to breakdowns and road accidents. It may seem more comfortable to drive with low-pressure tyres, but an under-inflated tyre is too flexible, which makes it uncontrollable. The drawbacks and dangers of under-inflated tyres

Remember to screw the tyre valve caps back onĪlternatively, you can take your car to a garage to ask a mechanic to check your tyre pressure – some garage chains, like Kwikfit, offer tyre pressure checks free of charge.Īs well as the tyres you have fitted, remember to check the pressure of your spare tyre every once in a while – you never know when you might need it. Check the tyre once again with the pressure gauge to see if you have the correct tyre pressure. If the tyre is underinflated, press the tyre pump or air compressor hose onto the valve and fill the tyre with air. If the tyre is over-inflated, press the small metal pin inside the valve with a screwdriver to let air out of the tyre. Press the pressure gauge onto the tyre valve until the hissing sound stops and the gauge gives you a reading. With your recommend PSI pressure reading in mind: You can pick up a pressure gauge for around £10, while a quality tyre pump usually costs between £15 to £30. If you prefer to check your tyres at home, you will need a reliable pressure gauge, a screwdriver and tyre pump or air compressor. In some cases there will be a PSI reading marked on the tyre, but do not mistake this figure as the recommended tyre pressure for your car – this is usually the maximum pressure that the tyre can take before popping. Remember to screw the tyre valve caps back on before you set off. Repeat these steps for the other three tyres. The pump will then inflate or deflate the tyre to match your chosen PSI value, and will start beeping when it is done. Connect the pump’s air hose to the tyre valve where the valve cap used to sit, and the machine should then show you a current pressure reading for the tyre. Insert the payment or required token, and then select the tyre pressure in PSI you would like using the +/- buttons on the air pump. Find the valve caps on each of your tyres, which jut out between the spokes of the alloys, and remove them (but keep them safe!). When safely parked in front of the machine: It usually costs about 50p to use the pump for four minutes, which should give you enough time to check all four tyres. Some of these tyre pump machines allow you to pay with coins, and others require a token purchased from the petrol station counter. Most petrol station forecourts have their own pressure gauge and air pump that you can use for a small fee. Please also note that if you are travelling with heavy luggage in the rear, or towing a trailer or caravan, it is wise to slightly increase the pressure in your rear tyres to avoid oversteer.Ĭhecking tyre pressure at a petrol station Tyre pressure psi to bar registration#
For this, you will need the size of the tyres fitted to your car, which is marked on the sidewalls of your tyres, and your car’s registration number.
You can also contact the customer services team of your chosen car manufacturer to find out the correct tyre pressure for your car. Still no luck? Not to worry – type your registration number into Kwik-Fit’s free tyre pressure search tool to get accurate tyre pressure recommendations for a number of different tyre sizes. If you can’t find the car’s manual, some passenger cars have tyre pressure information markings in the driver’s door pillar or inside the petrol flap. If so, you can use this handy converter from Which? to get a PSI figure from the listed BAR recommendation.

The manual may also give you the recommended pressure reading in a BAR figure. Most manufacturers recommend a tyre pressure of 32 to 35 PSI for the average passenger car. More often than not, the owner’s manual will tell you what your tyre pressure should be – it will give you a figure in pounds per square inch (PSI).
