Frequently Asked Questions
Where is the DOT code on my tire?
The DOT code is typically stamped on the sidewall of your tire. Look for a series of characters that start with "DOT" followed by letters and numbers. The last four digits represent the production date.
How do I read a DOT code?
The last four digits of a DOT code represent the production date. The first two digits indicate the week (01-52) and the last two digits indicate the year. For example, "4523" means the tire was manufactured in week 45 of 2023.
Why is the production date important?
Tire age is crucial for safety. Even if a tire appears to have good tread, tires older than 6-10 years should be replaced due to material degradation. Always check the DOT code before purchasing tires.
