A Federal Motor Carrier Safety Administration (FMCSA) study has shown tire pressure inflation systems can deliver fuel economy improvements.
The study, conducted by the FMCSA’s Office of Analysis, Research and Technology, examined the benefits of the Meritor Tire Inflation System (MTIS) by PSI in use with two fleets, Gordon Food Serice and Sheetz Inc.
The study looked at the effects, costs and benefits of the system, from a performance and safety perspective. In the end, it found the system delivered a 1.4% fuel economy improvement.
“We are pleased to see the results of the study which clearly reiterate the importance of MTIS for our customers on the road and their bottom line,” said Craig Frohock, general manager, global trailer, Meritor.
He said that in addition to fuel savings, the fleets in the study achieved longer tire life and experienced fewer road calls.
The MTIS system constantly measures tire pressures and when necessary, adds air to the tires to keep them at the appropriate pressure. It ca be combined with a ThermAlert option that notifies drivers of excessive wheel-end heat. About half of the companies using MTIS also opt for the ThermAlert option, Meritor claims.
