How old is my Toyo tire?
Type the dot date code from the Toyo label to see when it was built.
Example
- DOTDOT: meets U.S. safety standards
- 173Plant: 173 = Toyo Tire North America Manufacturing, Inc., White, GA, United States
- ABCDEFManufacturer's code
- 31Week: 31 (August)
- 20Year: 20 = 2020
Built Week 31 of 2020 (around August)
6 years, 2 months old
In replacement window. Inside the usual 6 to 10 year lifespan, so replacement could come any time. Worth budgeting for it.
How this was read
- "DOT" means the tire meets U.S. federal safety standards. The tire identification number follows it.
- The first three symbols, 173, are the plant code. NHTSA lists it as Toyo Tire North America Manufacturing, Inc., White, GA, United States.
- The plant list names the company that runs the factory. It may build tires sold under other brands.
- The next 6 symbols are the manufacturer's own code for size and type. They are not part of the date.
- The last four digits, 3120, are the date code.
- The first two, 31, are the week. The last two, 20, are the year: 2020.
- Week 31 of 2020 runs from Sunday, August 2, 2020 to Saturday, August 8, 2020.

Reading a Toyo serial number
Toyo tires carry the same DOT date code as every other brand sold in the U.S.
The date code is a week and year, like 2219 for week 22 of 2019. Read it on every tire, including the spare, since tires on one car often differ.

DOT date code, week and year
Used july 2000 to today. Example: DOTU2LLLMLR5107
The date code is the last group of the DOT number on the sidewall. The first two digits are the week and the last two are the year, so 5107 means week 51 of 2007.
Worked example: DOT 173 ABCDEF 3120 was built Week 31 of 2020 (around August), so it is 6 years, 2 months old as of October 2026.

Pre-2000 DOT date code, week and year digit
Used before July 2000. Example: DOTMJL9ABC218
Tires made before 2000 end the DOT number with three digits: the week, then the last digit of the year. Many 1990s tires add a small triangle after the code.
Worked example: DOT MJ L9 ABC 218 fits Week 21 of 1988 (around May) or Week 21 of 1998 (around May). The page above explains how to tell which.
| Code ends | Possible years |
|---|---|
| 218 with a triangle | 1998 |
| 218 with no triangle | 1988 or 1998 |
| xx0 with no triangle | 1980, 1990, or early 2000 |
