How can I tell how old my tires are? The good news: it's very easy to find out! On the sidewall of your tire you will see a DOT Identification Number and the last four digits of the number will reveal the week and year that the tire was actually built.
Example: Post-2000 Production Tire
This tire was manufactured during the 51st week of 2007 (LMLR5107).
Example: Pre-2000 Production Tire
This tire was manufactured during the 40th week of the 8th year of the decade (DFM408).
For safe operation, the current industry recommendation is to run your tires no longer than 6 years once they have been placed into service no matter how good they appear to be!
