Most people may have never thought about the age of their tires until recently. Now, many informed consumers have become concerned with the age of the tires on their vehicle, as well as the age of the tire(s) they're purchasing.
What is a reasonable age for a tire when making a purchase? Tire Rack works with many global manufacturers from around the world. It's not unusual for tires to be six to nine months old when we receive them direct from the tire manufacturers. We employ inventory rotation so that most of the tires we ship are less than a year old.
How fresh are the tires being sold by Tire Rack? As previously mentioned, Tire Rack employs inventory rotation so that most of the tires we ship are less than a year old. However, due to the global economy view taken by many tire manufacturers, Tire Rack isn't able to guarantee production dates. Tire Rack's expertly trained sales team may be able to help narrow down what may be available.
How do I know when my tire was produced? Every tire has the date of manufacture branded onto the sidewall as part of the DOT code. The last four digits on tires manufactured since 2000 indicates the week and year the tire was produced. The image above has the last four digits of 5107. This translates to the 51st week of 2007. Prior to 2000, the tire industry assumed that a tire would not be in service longer than ten years. As such, the date code consists of only three digits, two for the week and one for the year.
