The "DOT" marking indicates that the tire meets or exceeds the U.S. Department of Transportation's safety standard for tires.
Manufacturer Plant Code - "CC"
The first two letters following the DOT marking are codes to identify the manufacturer of the tire and the manufacturing plant.
Tire Size - "9L"
The third and fourth characters following the DOT marking are codes representing the tire size.
Brand Characteristics - "YYY
The final three or four letters are codes representing other significant characteristics of the tire as determined by the manufacturer.
Manufacture Week - "11"
The first pair of digits identifies the week the tire was manufactured. In this case, the tire was manufactured in the 11th week. The number 01 would indicate the first week of January, whereas the number 52 would indicate the last week of December.
Manufacture Year - "05"
The second pair of digits identifies the year that the tire was manufactured, in this case 2005.
