New Federal Motor Vehicle Safety Standard to Mandate Tire Pressure Monitoring Systems in New Vehicles

Summary

The Transportation Recall Enhancement, Accountability, and Documentation Act of 2000 requires motor vehicles to be equipped with tire pressure monitoring systems, and a new proposed standard (FMVSS 138) aims to establish this requirement for new passenger cars and light trucks, with two alternative versions to consider: one warning of under-inflation in up to 4 tires at 20% below recommended pressure, and another warning of under-inflation in up to 3 tires at 25% below recommended pressure.
