Do Tires Have an Expiry Date? How to Check & Key Tips to Stay Safe
Your vehicle's tires are its only contact with the road, making them one of the most critical components of your car's safety. But did you know that tires have an expiration date? Like food or medicine, tires age over time—even if they look brand new. Understanding tire expiration dates and how to check them can help you stay safe on the road and avoid unnecessary risks.
Do Tires Expire?
Yes, tires have a lifespan! While they don't have a strict expiration date like perishable goods, manufacturers and safety experts recommend replacing them every 6 to 10 years, regardless of tread wear. Over time, rubber degrades due to environmental factors such as heat, UV exposure, and moisture, which can cause cracks and reduce overall performance.
How to Find Your Tire's Expiration Date
Every tire has a manufacturing date stamped on its sidewall, known as the DOT (Department of Transportation) code. This code provides vital information about when your tire was made.
Where to Find the DOT Code
Look on the sidewall of your tire for a series of numbers and letters starting with "DOT." The last four digits in this sequence tell you the week and year the tire was manufactured.
How to Read the DOT Code
For example, if your tire has the code DOT XXXXXXX 3720:
The first two digits (37) represent the week of manufacture.
The last two digits (20) represent the year (2020).
The two penultimate digits (37) mean the tire was made in the 37th week of 2020.
If your tires are six years or older, it's time to inspect them carefully and consider replacing them, even if they still have tread left.
Factors That Affect Tire Aging
Several elements contribute to how quickly your tires degrade:
Exposure to Sunlight & Heat – UV rays and high temperatures speed up rubber deterioration.
Storage Conditions – Unused tires stored in a garage or warehouse still age, even if never mounted.
Driving Habits – Frequent high-speed driving and rough road conditions accelerate tire wear.
Proper Inflation – Under or overinflated tires can wear unevenly and age prematurely.
Useful Tips to Extend Tire Life
Regular Inspections – Check for cracks, bulges, or uneven wear at least once a month.
Proper Inflation – Maintain recommended tire pressure to reduce stress on the rubber.
Rotate Tires Every 5,000-8,000 km – Helps distribute wear evenly.
Avoid Direct Sunlight When Parking – UV rays can accelerate aging.
Store Properly—If you store unused tires, keep them in a cool, dry place away from direct sunlight.
Replace Old Tires, Even If They Look Fine – Rubber deteriorates internally, which may not be visible on the surface.
When Should You Replace Your Tires?
If your tires are 6 years or older, get them inspected by a professional.
If you see visible cracks, bulges, or deep tread wear, replace them immediately.
If you experience reduced grip or longer braking distances, don't wait—change your tires!
Final Thoughts
Tires don't last forever, and knowing their expiration date can help you drive safer and avoid accidents. You can ensure better road safety and vehicle performance by checking the DOT code, following proper maintenance, and replacing tires before they become a hazard.
