DETROIT (AP) — The U.S. government's highway safety agency has closed an investigation into reports of Michelin truck tire failures without seeking a recall.
The National Highway Traffic Safety Administration began investigating the 2014 model of Michelin's 22.5-inch diameter XZA tires in October after getting six complaints and a police report about seven crashes involving the tires.
But in documents posted Tuesday, the agency says the failures were not the fault of the tires. They were caused by a road hazard, owners using the tires on the wrong-size rim, or a combination of violating tire load limits, letting the air pressure get too low or traveling at a higher-than-rated speed.
The investigation covering more than 32,000 tires found 16 complaints, three crashes and two police crash reports.
