Check that tyre pressure
Many people do have a good intention to check the tyre pressure of their car regularly, but the execution could be better. A resolution is one thing, but keeping it is another. You've probably experienced it yourself: you've filled up with petrol and decide to check the tyre pressure, but you don't have the exact change to put it in the machine, or someone has just made the same intention in front of you. Very recognisable, because I have little patience myself and it is easier to think "it will come next week". Despite my own reprehensible behaviour, I would like to point out that tyre pressure is very important for safety, tyre wear and fuel consumption.
Consequences of incorrect tyre pressure
The tyre pressure of your car is more important than you think! Incorrect tyre pressure can cause the braking distance to be longer, the tyres to wear out more quickly and/or irregularly and fuel consumption to increase.
Consequence of too high tyre pressure
Some people think they are more bar (air) into the tyre than prescribed, in order to reduce fuel consumption.
But too much bar in the tyre means that the tyre is not fully touching the road surface, which affects braking distance and cornering grip. The minimal amount of fuel you save is then spent on a new set of tyres, as they wear down faster and more irregularly.
Consequences of insufficient tyre pressure
The people who never check the tyre pressure and drive around for a year like this usually end up with insufficient bar in the band. Due to temperature differences, the pressure usually drops below 2 bar. If the pressure is too low, the tyre is extremely soft and there is a risk that it will burst at high speed or when cornering. Braking distances are longer, fuel consumption increases and the tyre wears out more quickly in this case too.
How often should you check tyre pressure?
Although the Netherlands has no extreme weather conditions yet, it is advisable to check the tyre pressure every month. Perhaps after washing your car, it is a good time to check the tyre pressure. In Groningen there is Geling's where you can do this for free after washing your car, at Loogman it costs at least 50 cents.
If you are going on holiday to a country with large temperature fluctuations, it is wise to check the tyre pressure every week.
How much bar should my car have?
This information is almost always on the side of a pump. Once you have found the right information, unscrew the valve caps (keep them in a good place). Then, if necessary, insert coins into the pump and set the right tyre pressure (e.g. front 2.2 bar and rear 2.3 bar). Then just put the hose on the valve and the tyre is inflated or deflated, depending on the amount of bar in your tyre. Do not be alarmed if the tyre slowly deflates a little, in this case your tyres were over-inflated. As soon as the pump is ready, it starts beeping. Repeat this with the other tyres and then you can safely hit the road again.
Tyre pressure by brand and model
The tables below show the tyre pressures for each make and model. However, these are the factory rims and tyre sizes. If your car does not have original tyres and rims, the tyre pressures may be different.
The models for which the tyre pressure is known to us are: 147, 156, 166, GTV/Spider.
The models for which the tyre pressure is known to us are: A2, A3, A4, A6, A8
BMW has so many combinations that we have created a separate page:
