Air pressure in car tires is an important issue, which unfortunately many drivers still consider unimportant. Not every driver has been regularly checking the air pressure in his tire for a long time. A tire pressure that is too low or even too high can cause serious problems. If the tire pressure is too low, driving behavior may deteriorate and fuel consumption may increase. In addition, a tire pressure that is too low can cause damage to the tire.
A air pressure too high on the other hand, can lead to a blowout. For these reasons alone, it is important to check the air pressure regularly. In this case, regular means one or two times a month.
However, there are now supporting systems that a driver can have installed in the car. So-called air pressure warning systems can already be integrated in new vehicles. However, there is also the option of having such a system installed for older vehicles.
What does the air pressure warning system do?
Air pressure warning systems is the generic term for warning and control systems that are used to monitor the air pressure in a car tire and either warn the driver or display the tire pressure if the tire pressure is too low or too high. A distinction is made between indirect and direct systems.
Comparison of direct and indirect systems
Indirect systems follow a process that can infer the tire pressure from the speed of the wheels. The speed of the tires is recorded by the ABS systems in the vehicle. The printing systems use two physical properties for the acquisition Rolling circumference and the frequency effect. If you want to use such a system, you must note that when a new air pressure is supplied or when changing the wheels, the reset button must be pressed in order to continue to receive an accurate display.
The direct systems work with a different process. They measure the air pressure and the tire temperature. This data is then transmitted to a control unit in the vehicle. The direct systems can be easily retrofitted, for example, by attaching them to the rim or screwing them onto the valve.
The installation of such a system should, however, be carried out by a specialist, since precise installation and adjustment are necessary in order to obtain an exact measured value.
What are the advantages of a tire pressure monitoring system?
The fact that air pressure is important has already been mentioned. The control systems offer numerous advantages that every driver should consider. On the one hand, these control systems offer more driving safety on the roads because they prevent both low and excessive tire pressure. The correct tire pressure enables sufficient traction on the road, which reduces accidents.
Is the control system now mandatory in Germany?
The tire pressure control system is mandatory, but not yet in all vehicles. The EU has decided that vehicles manufactured after November 1st, 2012 need such a system. However, there is also a restriction here, since only vehicles of the M1 / M1 G class must have a control system ex works from 2012. This group generally includes cars, off-road vehicles and campers. The manufacturer, the country of origin or the factory is completely irrelevant, since it applies to all vehicles.
It has only been mandatory since 2014 that every new vehicle has a tire pressure monitoring system ex works. In addition, the tire pressure monitoring system has become part of the main examination list. Retrofitting this system costs around 150 euros and can be worthwhile, although you should keep in mind that the system will also make the tires more expensive in the future.
