DOT number
Posted by Jacob from Mumbai, OT, IN on April 6, 2007
In DOT number, I understand first two digits denotes plant code and last 4 digits for week & year. Is the two digits after plant code indicates tire size? If so, how do I understand the coding?
U.S. DOT Tire Identification Number...
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 manufactured, and the last four numbers represent the week and year the tire was built. For example, the numbers 3105 means the 31st week of 2005. The other numbers are marketing codes used at the manufacturer's discretion. This information is used to contact consumers if a tire defect requires a recall.
