Tires with low inflation pressure to deform more than necessary and therefore have a higher rolling resistance. The result: the fuel consumption increases. Also reduces the life of tires and the braking distances are longer. The Society for Technical Supervision (GTÜ) therefore recommends regular tire pressure check, save the right values for fuel and provide safety.
Tires which account for up to 25 percent in fuel consumption of a vehicle. Responsible for this is especially the rolling resistance, which provides that the face of ever increasing fuel prices, a high savings potential. A car tire falls through the vehicle weight in the range of contact area about 10 to 15 percent and adapts to the road.
It changes its round shape and becomes flat. The resulting increased resistance drive consumes energy that is converted into heat. The tire will heat up so well while driving. If the correct Fülldruckwerte not met, fall of an even stronger tires, rolling resistance and heat take too drastic.
This can lead to dangerous tire failure, warns GTÜ. A minimum pressure of 0.2 bar increases fuel consumption by about one percent at 0.4 bar there are only two per cent and 0.6 bar below the recommended level there are about four percent more fuel. Also reduced to a low air pressure tire life.
At 0.3 bar pressure, reducing the mileage has decreased by 30 percent. Moreover, extending the stopping distance. Thus the driving safety is impaired. The standards authority recommends, therefore, check the tire pressure at least every four weeks. To ensure a low rolling resistance, the prescribed each tire pressure be exceeded by up to 0.3 bar.
A further increase in pressure would bring disadvantages in terms of comfort, however, wear and handling. Of course, also applies to so-called fuel-saving or low-resistance tires that only the proper air pressure brings the best results the way: short routes with cold tires with high rolling resistance and thus over-connected.
