Industry Reports About TPMS Trends, Tire Pressure, Safety and Fuel Efficiency

TPMS Effectiveness in Proper Tire Pressure Maintenance – In this November 2012 study, NHTSA completed an extensive survey of vehicles to measure the effectiveness of TPMS in protecting drivers from underinflation situations. The data showed that the presence of TPMS was estimated to result in a 55.6% reduction in the likelihood the vehicle would have one or more severely underinflated tires.

Tire Pressure Monitoring System FMVSS No. 138 – The final regulatory impact analysis of the TREAD Act, from the National Highway Traffic Safety Administration, published in 2005

NHTSA Final Rule Document – This final rule establishes a new Federal motor vehicle safety standard (FMVSS) requiring installation of a tire pressure monitoring system (TPMS) capable of detecting when one or more of a vehicle's tires is significantly underinflated. This final rule responds to a mandate in the TREAD Act.

Tire Pressure Maintenance– A Statistical Investigation – NHTSA conducted several surveys and studies to estimate and compare the benefits of direct and indirect TPMS. The results are presented in this report.

Fuel Economy Guide 2010 – The U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) produce the Fuel Economy Guide to help car buyers choose the most fuel efficient vehicle that meets their needs.

Bridgestone® Road Driving Test Video – Watch this video to see the significant safety risks and handling affects of low tire pressure for drivers.

Department of Transportation FMVSS 138 compliance test – Read an analysis of Office of Vehicle Safety Compliance Test Procedure TP-138-03, conducted on the 2009 Audi A6 four-door passenger car.


EU drivers still under-inflate their tyres – In a new survey, Bridgestone has found that 71% of motorists in Europe are driving on under-inflated tyres, wasting 2 billion litres of fuel a year, and adding 4.8 million tons of CO2 emissions.

Regulation (EC) 661/2009 – The voted-upon and published Regulation (EC) 661/2009 of the European Parliament and the Council, concerning the Type-approval Requirement for the General Safety of Motor Vehicles. Includes a mandated fitment of TPMS on M1 vehicles (Article 9.2).

European Parliament study on Type-approval Requirements for the General Safety of Motor Vehicles – A study that presents general information on tyre pressure monitoring systems and an analysis of existing data, including scientific evidences and conclusions about TPMS.

Draft: United Nations Economic and Social Council R64 Regulation on TPMS – This draft regulation is based upon the GRRF TPMS Task Force Conclusions and the GRRF Cost Benefit Analysis of Direct TPMS.

United Nations Economic and Social Council GRRF TPMS Task Force Conclusions – These conclusions provide a distribution of actual tyre pressure on the road in various countries; discuss detailed analysis of the data and the contribution of various types of TPMS to reduce this underinflation; assert the effects of underinflation on fuel consumption, CO2 emissions, tyre wear, and road safety; and outline the causes of underinflation.

United Nations Economic and Social Council GRRF Cost Benefit Analysis of Direct TPMS – This report from the UNESC is a cost benefit analysis of direct TPMS.

The European Tyre and Rim Technical Organisation Position Paper on UNECE R64 Regulation on TPMS – This white paper asserts the positions ETRTO takes on certain measures proposed within the UNECE's regulation on TPMS, including cases in which measures are deemed insufficient.
