Pressure Systems International’s August issue of Commercial Fleet Tire Digest is now available. This month’s issue tackles the EPA and DOT/NHTSA proposed Phase II greenhouse gas and fuel economy standards.
In it, PSI references the fuel economy benefits that can be achieved through the use of low-rolling resistance tires.
“Low rolling resistance tires are recognized as having an impact on vehicle fuel economy. The rulemaking notes on page 182 that differences in rolling resistance of up to 50 percent have been identified between tires of one make/model versus a different tire make/model,” PSI says. “However, just because a tire is marketed as ‘low-rolling resistance’ does not guarantee the actual best fuel economy in the real world because not all tires are the same.”
PSI also references the importance of proper inflation when maximizing the benefits of those tires.
“Keeping tires properly inflated all the time is the only way to assure that these fuel efficient tires perform as expected. Running a low-rolling resistance tire underinflated eliminates any fuel economy benefit,” the company says.
