For example, 0302 signifies that the tire was made during the third week of 2002.
(Tires made prior to 2000 used a three-digit date configuration at the end of the DOT code.
To find your tire's date code, identify the code on the tire that begins with 'DOT'.
The 'DOT' should be followed by a series of four letters and/or numbers.
Some manufacturers place an additional code with a specific serial, which identifies the specific tire model (a tire type code).
This optional number is located on the sidewall opposite the DOT number.
Commercial treads also include codes, which are used to detail retread information.
This code is generally found on the lower sidewall near the original DOT code.
And in 2008, the agency mentioned tire age as a hazard in a consumer advisory about tire care in the summer months.
While a performance standard would certainly ensure that tires were more robust, absent a change in the date code, consumers will still be in the dark about the age of their tires.
A tire’s weight and speed limits are indicated by the tire service description; a short code located on the sidewall.
Automobile tires are described by an alphanumeric tire code (in American English and Canadian English) or tyre code (in British English, Australian English and others), which is generally molded (or moulded) into the sidewall of the tire.
All new tires sold in the United States must have a DOT number cured into the lower sidewall of one side of the tire.
