Motorcycle tires, like other tires, usually have a manufacturing date stamped on them instead of an explicit expiration date. The manufacturing date provides information about when the tire was produced, allowing you to assess its age and determine if it's still safe to use. To check a motorcycle tire's manufacturing date, follow these steps:
Locate the sidewall: Inspect the sides of the tire to find the sidewall. It is the outer part of the tire that faces outward when mounted on the motorcycle.
Look for the DOT code: The U.S. Department of Transportation (DOT) requires tire manufacturers to imprint a code on the sidewall. This code typically begins with the letters "DOT" and is followed by a series of numbers and letters.
Identify the manufacturing date: Within the DOT code, the last four digits represent the tire's manufacturing date. The first two digits indicate the week, while the last two digits indicate the year of manufacture. For example, if you see "DOT XXXX 1518" on the sidewall, it means the tire was manufactured in the 15th week of 2018.
Determine the tire's age: Once you have identified the manufacturing date, you can calculate the tire's age by comparing it to the current date. Keep in mind that tires typically have a recommended lifespan of around 5 to 6 years, regardless of their tread depth or apparent condition. If the tire is older than this, it may be advisable to consider replacing it, even if it appears to be in good condition.
Remember that the manufacturing date indicates when the tire was produced and doesn't necessarily represent its exact expiration date. Tire lifespan can be influenced by various factors such as usage, storage conditions, and maintenance. Regularly inspecting your motorcycle tires for signs of wear, damage, or degradation is essential for ensuring your safety on the road. If you have any concerns about your tires, it's recommended to consult with a professional tire expert or your motorcycle manufacturer.
