US Court Rejects Tyre Monitoring System Regulation
In the USA, a panel of three federal judges has rejected a proposed tyre pressure monitoring system (TPMS) as it allowed too great a margin for error. TPMS was made compulsory in new cars following the Ford Explorer/Firestone tyre episode. The National Highway Traffic Safety Administration was ordered to come up with a TPMS for cars and it offered two systems – one which required a sensor on all four tyres (direct system) and one which used existing technology systems, such as ABS, to estimate pressure (indirect system). Consumer groups claimed that the second system was not effective all the time, and thus did not meet the law’s requirements, and the judges agreed, ordering the NHTSA to formulate a new rule.
