UN Regulation No. 141
Tire Pressure Monitoring Systems

Uniform provisions concerning the approval of vehicles with regard to their tyre pressure monitoring systems

Program to separate tyre-pressure monitoring systems provisions from UN Regulation No. 64 on spare tyres. The primary issue is to remove provisions from UN R64 that will not be included in the initial phase of the International Whole Vehicle Type Approval (IWVTA) system.
