To determine the age of a tire, look at the date code on the tire sidewall.
The tire identification code is a combination of eleven or twelve letters and numbers that identify the manufacturing location, tire size, manufacturer's code, and week and year the tire was manufactured
Beginning in 2000, the data codes is comprised of 4 digits.
Before 2000, the date code had three digits.
From 2000 on: DOT XXXX XXX XXXX
Last four digits: date code (week and year of manufacture)
Example: 0104 - the first week of 2004.
Before 2000: DOT XXXX XXXX XXX (older three-digit date code format)
Last three digits: date code (two for the week / one for the year)
Example: 103 - the tenth week of either 1993 or 1983.
If any of your tires are over 10 years old, they should probably be replaced.
