China adopts tire-pressure regulation

  • 04-Dec-2008 10:37 EST

China's central government recently published a draft standard on tire-pressure-monitoring systems that is significantly more stringent than U.S. Federal Motor Vehicle Safety Standard 138, according to InterRegs. For instance, the standard would require that the system be capable of detecting when any tire drops below 75% of its recommended inflation pressure within 6 s, even when the vehicle is stationary. The system would also be required to identify which tire is under-inflated and to display the actual pressure in each tire at the driver’s request. The standard will be applied on a voluntary basis initially, but compliance may become mandatory in the future.
