Michelin North America is recalling some 841,000 light truck and commercial light truck tires due to tread separation concerns.

Specifically, the tiremaker is recalling BFGoodrich Commercial T/A A/S and Uniroyal Laredo HD/H tires sold in the U.S., Canada and Mexico.

While company officials said they cannot “pinpoint” an exact cause, it discovered the tread separation concerns it found from regular field checks. “A tire is a complex thing. There is rarely one thing you can pinpoint to cause something like this,” said Mike Wischhusen, MNA technical director.

MNA said, “The customer return rate for tread and/or air loss was 0.017%, which equates to about 143 tires. However, any tire produced in the range of the recall could exhibit these conditions.”

The tires under recall include:

• LT235/85R16 120Q
BFGoodrich Commercial T/A A/S LRE produced from the 13th week of 2010 through the 29th week of 2012;

• LT245/75R16 120Q
BFGoodrich Commercial T/A A/S LRE produced from the 13th week of 2010 through the third week of 2012, and from the 13th week of 2011 through the 52nd week of 2011;

• LT235/85R16 120 Q Uniroyal Laredo HD/H LRE produced between the 13th week of 2010 and the 29th week of 2012;

• LT245/75R16 120 Q Uniroyal Laredo HD/H LRE produced from the 13th week of 2010 through the third week of 2012, and from the 13th week of 2011 through the 52nd week of 2011.

MNA said the tires in question, typically fitted to commercial light trucks and full-sized heavy-duty vans, are no longer being produced.
