I just purchased a K1200RS which needed a new rear tire but after taking it home (in the rain

) pulled into the garage and noticed some bits of tire shedding from the right sidewall.
Is this normal when tires get older? Its on the para lever side so I double checked for contact wear and couldn't find any.
Before spending a few hundred $$ to replace my tire, I want to make sure the new one doesn't get chewed up as well.
