Age of "new" tires

Considering that most tire manufacturers now consider 7 years to be the maximum age I wouldn’t accept 3 year old tires on a new install. Some tire shops will not service tires more than 7 years old now too.

I could understand tires that were maybe a year to 18 months. I’d bring up anything much more than that. I would suggest bringing your receipt and going back to that shop.
