Read your tire's DOT code
The code after "DOT" on the sidewall names the plant that made the tire and, in its last four digits, the week and year: 2219 is week 22 of 2019.

How to read a tire DOT code
Every tire sold in the US carries a Tire Identification Number after the letters "DOT". The first two or three characters are the plant code (three since 2015's rule; older plants' codes gained a leading "1", so UT became 1UT), then come the manufacturer's codes, and the last four digits are the week and year it was made. The check reads the plant from NHTSA's register of tire plants and compares the build week with the production windows NHTSA tire recalls print.
Plant code
Two or three characters right after "DOT", from NHTSA's register of tire plants: the factory, its city and country.
Date code
The last four digits: week then year. 0117 is the first week of 2017. Codes with three digits are tires made before 2000.
Recall windows
NHTSA tire recalls that print a DOT code range, a build week or dates. Add the size and brand to check the ones that name no plant.
Frequently asked questions
How do I tell how old my tires are?
Find the code that starts with "DOT" on the sidewall; the full code may be on one side only. Its last four digits are the week and year the tire was made: 3523 means week 35 of 2023. Enter the whole code above to see the exact week and the tire's age.
Does no match mean my tire is not recalled?
No. Many tire recall notices give no dates or plants, and some list ranges only in attached charts. Treat a match as a reason to call the tire maker with the full code, and no match as "not found in the published windows". NHTSA lists every tire recall at nhtsa.gov/recalls.
When should old tires be replaced?
There is no federal age limit. Tire and vehicle makers publish their own recommendations, and tread depth, cracking and storage matter as much as the date. Ask the tire maker or a tire shop about yours.
