Beru Chosen as BMW TPMS Supplier in US

BMW has chosen the German company Beru AG as its supplier of tyre pressure control systems for BMW vehicles destined for the US market. Beru AG manufactures the Beru Tire Safety System (TSS), a unit that directly records tyre pressure when a vehicle is either stationary or moving.
The US Tread Act compels all vehicles approved for sale in the US from September 2007 model year onwards to be fitted with a tyre pressure control system. Such a system must be capable of independently monitoring pressure in all four tyres simultaneously, a task that requires the use of a direct recording tyre pressure system such as the Beru TSS.

The second-generation Beru TSS system that BMW is fitting to its US market vehicles features a trigger transmitter and will alert the driver if tyre pressure is down by as little as 0.2 bar (2.901 psi), an amount that can lead to increased tyre wear. It will also provide warning of gradual or sudden losses in pressure.

The Beru TSS was introduced in 1998 and has been factory installed by a number of manufacturers, including Audi, Bentley, Bugatti, Ferrari, Maserati, Maybach, Mercedes-Benz, Porsche and Volkswagen.
