Tire pressure monitoring systems become mandatory in U.S.
Washington, D.C. – A U.S. federal requirement for tire pressure monitoring systems (TPMS) will reach full compliance on September 1, 2007. Following a phase-in period which began in 2005, all cars, trucks and SUVs with a gross vehicle weight of 4,536 kg (10,000 lbs) or less, manufactured on or after September 1, must have a system that monitors all four wheels and warns the driver if any tire is under-inflated by 25 per cent or more of its recommended pressure.
While many vehicles are sold in Canada with TPMS, Transport Canada has not called for similar legislation, and says it will monitor the effectiveness of the systems before making any decisions on mandatory requirements.
