Ervin Equipment adding tire system to new, used trailers

Jason Cannon June 14, 2013

Ervin Equipment has formed a vendor/customer relationship with San Antonio-based Pressure Systems International (P.S.I.) to begin offering the Meritor Tire Inflation System by P.S.I. on its used and new trailers.

Fleets require trailer tires to run at anywhere from 85 to 125 psi and Meritor’s Tire Inflation System by P.S.I. keeps trailer tires at the correct pressure while they are rotating via the tractor’s onboard compressor, the company says. Air lines have a pressure protection valve and control box to regulate the tire pressure and the system offers a fuel mileage increase of 1.4 percent, a forecasted 10 percent extended tire life.

“This one-time investment will most likely pay for itself in the first 12 months, and customers then benefit from the unit for the next 8 to 10 years. By the time you trade the trailer in, the automatic tire inflation system will have saved the fleet owner a healthy chunk of cash,” said Ervin Vice President of Sales and Marketing Jeff Weber.

Underinflated tires are susceptible to internal heat buildup and increased rolling resistance, causing up to 5 percent reduction in fuel economy. Tires underinflated by only 6 psi could lead to tire failure and as much as a 25 percent reduction of tread life.

Weber says, customers who pay for the automatic tire inflation system gain up to 50 percent of the original systems purchase price back during the resale of the trailer. According to Jonathan Gravell, sales and marketing coordinator at P.S.I., the unit also makes the trailer easier to sell.
