| Description of the problem | Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) i purchased four firestone fr710 tires on august 27, 2009 from a local firestone dealer for my 2006 toyota sienna. Recently we noticed that the front right tire's tread was delaminating all around the perimeter of the tire where the tread meets the sidewall. In some places there was 1/2" of separation. Upon closer inspection it was found that two of the other tires were also starting to separate. This was evident due to small hairline separations running around the perimeter of the tires in the same region as the worst tire. These tires were all made within a week of each other with date codes of 1909 and 2009 (19th and 20th week of 2009). The dot number is w56v710. The vin of the vehicle is [xxx] . The mileage at purchase was 49,328 and the current mileage is 61,491. Photos of the tires are available. |
