Due to the significant influence tire pressure has on vehicle safety and efficiency, Tire Pressure Monitoring system (TPMS) was first adopted widely by the European market as an optional feature for luxury passenger vehicles in the 1980s. The first passenger vehicle to adopt tire-pressure monitoring

(TPM) was the Porsche 959 in 1986, using a hollow spoke wheel system developed by PSK. In 1999 the PSA Peugeot Citro decided to adopt TPM as a standard feature on the Peugeot 607. The following year (2000), Renault launched the Laguna II, the first high volume mid-size passenger vehicle in the world to be equipped with TPM as a standard feature.

Being now a standard system, TPMS is a direct tire pressure monitoring systems (TPMS) that is standard equipment on every vehicle sold in the U.S.

after September, 2007. The criteria for TPMS standardization is that the vehicle must have only four wheels (no dual-wheeled trucks or motorcycles), and weigh less than 10,000 lbs. Direct TPMS use a sensor in the wheel/tire to wirelessly relay pressure back to the driver via a display inside the vehicle. Some vehicles have a digital screen that continuously shows all four tire pressures (five if spare has sensor). Others simply flash a “low tire pressure” light on the dash. Additionally, there are two different styles of sensors for a direct system: a valve sensor and a strap/band sensor. Only valve sensors are used on BMW direct system-equipped vehicles.

If you bought an aftermarket SmarTire TPMS, its sensors are held on by a strap around the barrel of the wheel. At Tpms Direct we carry fitments for all years and all series of BMW.
