Tires long have been the biggest maintenance cost for truck fleets, and managing those costs is the difference for most fleets between profit and loss, according to Al Cohn, director of new market development and engineering support for Pressure Systems International. In 2011, average prices for commercial tires increased about 50 percent, Cohn told the audience at the 30th annual Clemson University Tire Industry Conference at Hilton Head, S.C., April 23-25. "Some tires rose 60 or 70 percent," Cohn said. "Big fleets paid a little less, but the little guys really got hurt.' However, commercial tire prices were stable in 2012 and 2013, and have been so far this year, he said.
