U.S. DOT Tire Identification Number
(TIN): This begins with the letters "DOT"
and indicates that the tire meets all federal
standards. The next two numbers or letters
are the plant code where it was manufac-
tured, the next two are the tire size code
and the last four numbers represent the
week and year the tire was built. For exam-
ple, 1510 means that the tire was manu-
factured during week 15 of 2010. The num-
bers in between are marketing codes used
at the manufacturer's discretion. This infor-
mation helps a tire manufacturer identify a
tire for safety recall purposes.
65: The ratio of the tire's height to its width
in percent.
