WASHINGTON -- DaimlerChrysler AG is advising U.S. customers to replace new car and truck tires after six years, even if there is no sign of wear, beginning with 2006 models.
The warning will be placed in Chrysler, Dodge and Jeep owners' manuals, following a practice the company established in Europe. A few 2005 Chrysler Group models carry the warning.
"Tires and spare tire should be replaced after six years, regardless of the remaining tread," the warning reads. "Failure to follow this warning can result in sudden tire failure. You could lose control and have an accident resulting in serious injury or death."
Ford Motor Co. began warning customers to replace older tires on its Web site a few weeks ago. It will also include a warning with all 2006 models.
The companies are responding to new research that suggests tires can degrade rapidly as they get older, regardless of how much they are used.
Chrysler spokesman Max Gates said the tire warning was added as part of an ongoing review of safety information provided in owners' manuals. "We're trying to get our customers to focus on tire maintenance," Gates said. "It is important to raise this issue. It's often overlooked."
The moves by Ford and Chrysler represent a break from the U.S. tire industry, which insists the research about tire aging is inconclusive. The Rubber Manufacturers Association says there is no set period after which all tires represent a safety risk.
