What does the DOT number mean?
DOT stands for Department of Transportation — the U.S. authority that sets requirements for tyre production and identification.
A DOT code consists of four digits:
- The first two digits indicate the week of production
- The last two digits indicate the year of production
Example: DOT 2619 means the tyre was produced in week 26 of 2019.
Where can you find the DOT number on an earthmoving tyre?
The DOT number can be found on the sidewall of the tyre, usually following the letters “DOT”.
For high-speed cranes and other heavy earthmoving machines, this code is often part of the tyre’s serial number. The exact location and format may vary by manufacturer.
Why is the DOT number important?
Checking the DOT number is crucial for:
- safety inspections and periodic checks
- purchasing used earthmoving tyres (to verify age)
- preventive maintenance, as ageing rubber becomes harder and more prone to cracking
- insurance purposes, where the production date may affect liability
As a general rule, tyres older than 10 years are often not recommended for use — especially under heavy loads or at higher speeds.
