Okay at the risk of sounding stupid, I ask this question.
I recently heard that tires actually have an expiration date?
That after X-amount of years even if the tread is good, the rubber is bad?
Can anyone clarify this for me please?

Thanks.

 

Tires generally have a shelf life of 5-7 years. After that; depending on what kind of conditions they have been in, they may start to dry rot from the inside out. You generally don't want to ride on a tire any older than 7-8 years.

 

ok thanks.. I'll probably replace every 5 years just to be safe.
