Pressure Systems International’s June issue of Commercial Fleet Tire Digest is now available.
Understanding Low-Rolling Resistance Tires is the headline of this month’s issue.
“Every commercial tire manufacturer markets low rolling resistance (LRR) tires. The major benefit of spec’ing them is to improve vehicle fuel economy and there is normally a price premium associated with these tires,” PSI says.
PSI says to make the SmartWay verified LRR list, tires are run on a 67 in. wheel dynamometer at 50 mph. If the measured tire rolling resistance (RR) shows a 3 percent or more improvement versus a baseline tire, then that tire make and model can make this verified list. The actual tire rolling resistance assumes the tire is running properly inflated.
“In the real world this is a big issue, especially on poorly maintained trailer tires. This is one of the reasons why automatic tire inflation systems on trailers has become so popular with fleets,” PSI says.
