How to Measure Tyre Pressure Correctly

How to measure tyre pressure correctly? Thousands of drivers ask themselves this question every day, and taking a good pressure reading prevents many scares on the road. Tyres are a fundamental part of the vehicle, as they are the connection between the vehicle and the road surface.

As well as checking the condition of the tyres, it is essential to check the pressures at least once a month, and all the more so if you are planning a trip.

What happens when the tyres do not have the correct pressure?

It is extremely important that the tyres have the correct pressure, but if for any reason they lose some, it is advisable to be aware of the risks. Firstly, underinflated tyres heat up more. This causes greater friction, which means the vehicle consumes a lot more fuel.

In addition, running tyres with low pressure can cause the rubber to deform, with the risk of possible blowouts. Loss of control of the vehicle is also a consequence of failing to maintain the pressures.

What pressure should the tyres be at?

To know how to measure tyre pressure correctly, it is essential to know the exact pressure the tyres need. The exact figure can be checked in the owner’s manual that comes with the vehicle. On most models, there is also a sticker, located on the door sills or on the fuel filler flap, which gives the figures recommended by the manufacturer according to the wheel sizes, the number of passengers and the load carried.

For a correct pressure measurement, it is advisable to have a pressure gauge to hand.

How to measure the pressure correctly?

The tyre pressure should be measured when the wheels are ‘cold’, that is, before setting off or after driving no more than five kilometres. If, on the other hand, the tyres cannot be inflated before setting off, you must remember to add 0.3 bar to the figure given by the manufacturer.

It is recommended to check them at least once a month, since tyres tend to lose pressure over time. Over-inflating them is not advisable, as this would lead to a loss of vehicle control and therefore a loss of grip, as well as uneven wear across the centre of the tread.

Although fewer and fewer models include one, do not forget to check the condition of the spare wheel. It is important to check its pressure and also to add one kilogram more than the manufacturer specifies. This way, the driver will ensure it is in good condition when it is needed.
