DUNLOP TIRES DO NOT HAVE THE MANUFACTURING DATE.

Motorcyclists typically get 7,000 - 10,000 miles on their motorcycle tires. So for some, the motorcycle tire may not last long enough – from a chronological age standpoint – to worry about. 

Many of us may not put that much mileage on our motorcycle tires if the motorcycle is not our primary vehicle. We generally don’t know the age of the tire when it’s put on our bike. This isn’t to say your dealer sold you a used tire instead of a new one. 

The tire begins to age as soon as it is manufactured..

Exposure to oxygen, sun light, heat, and use all work to break down, wear out and harden the rubber compound used in the tires, whether the tire is on a bike or not.
