Tire pressure warning system

About the DWS team

Within DUNLOP TECH GmbH at Hanau we develop and apply the software of the DUNLOP Tech Warnair tire pressure loss detection system for passenger cars and light commercial vehicles (categories M1 and N1). The requirements according to UN ECE R64 are fulfilled.

DUNLOP TECH Warnair is an indirect measuring system, i.e. it does not require any components inside the tire or on the wheel. It monitors the change in tire characteristics with changing tire pressure by using the signals and measuring parameters already available within the vehicle solely by software. For this reason, both its manufacture and in-vehicle operation are to be considered as CO2 neutral.

As one of the leading software developers in the automotive sector today we are innovative and anxious to ensure continuous further development. In co-operation with our partner BOSCH and their prestigious customers, such as Hyundai, Honda, Mazda, PSA, Opel, Volkswagen-Group including Audi, Skoda, Seat, VW we contribute our products to reduce fuel consumption and increase driving comfort. When performing our system tests we are supported by test drivers from Wand & Reichwein GbR . Additionally, when performing the required winter tests, we rely on Sweden's Icemakers expertise.

In 2011, according to Germany’s Federal Statistical Office, on German roads alone, 985 accidents involving personal injury were caused by technical defects of the tires. A non-negligible share of these accidents is due to incorrect tire pressure. If a tire is losing air the driver may not notice until it's already too late. Low pressure not only reduces vehicle stability but also results in over-heating which may lead to a blow-out. Especially with slow pressure losses the driver often notices no change of the vehicle performance at all.

Even without the drastic consequences of an accident, however, incorrect tire pressure has a negative impact on the environment and the driver's purse. Only an appropriately inflated tire gives the lowest possible rolling resistance, wears evenly and thus achieves its maximum wear mileage. Moreover, such parameters as braking distance, cornering stability, and driving comfort depend on the tire pressure too.  Undesireable consequences occur in particular when the tire pressure is too low. While driving stability is reduced, excessive heating of the tire causes structural damage and also increases fuel consumption and CO2 emissions.

Important note: While a tire pressure warning system protects you from any losses in tire pressure that would have remained undetected otherwise, it does not release the driver from the responsibility to check tire pressure at regular intervals.
