Re: 10 Year old tires...
Reply #34 –
I had my tire dealer check my 5 year old non-Michelin tires on my sob years ago. Made it almost 100 miles before an outside dual blew, doing enough damage to be remembered 20 years later.
I change my Michelins at 5 years or first sign of sidewall checking.
On another tack, I bought an in mounted spare for Alaska last year. At what point in time should I chuck it? All seven tires were made in 2018.
