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.

Hi there & welcome,

When I was buying tyres recently I came across this "wheel & tyre bible" at the link below. Basically says a tyre has a 6 year life, used or not!?

oh cool thanks for the link!
