Washington DC--The Specialty Equipment Market Association, the Alliance of Automobile Manufacturers and the consumer watchdog group Public Citizen have joined the chorus of organisations calling on the National Highway Traffic Safety Administration for changes to the final rule on tyre pressure monitoring systems.
SEMA was concerned, among other things, about the standard's silence on whether the TPMS malfunction indicator lamp can be replaced with an equivalent system, and that it contains no requirement to reprogram TPMSs to accommodate replacement tyres. The Alliance asked for several technical changes, including some to the table for minimum activation pressures for Load Range D and E tyres.
Public Citizen said the standard fails consumers because it gives them no way to know whether their replacement tyres are compatible with their TPMSs until after the tyres are mounted on the vehicles. Other petitioners for changes in the TPMS final rule include the Rubber Manufacturers Association, the Tire Industry Association, Volkswagen of America Inc. and Sumitomo Rubber Industries Ltd.
