DOT code
DOT is short for “
Department of Transportation” and refers to a code made of three or four numbers molded into a tyre’s sidewall. This code indicates the tyre’s manufacturing date and implicit how old that tyre is. For instance, “327” indicates a tyre that was manufactured in the 32nd week of 1997. Starting from 2000, the DOT code has four digits. For example, “1602” refers to a tyre that was manufactured in the 16th week of 2002.
