I hope that you found in your garage parked ! That's a good reason to check older tires. But one thing you got your money's worth
Getting 45 years out of a tire could make me settle for the pair of 80% tread goodyears I saw for sale at the recent Portland swap meet for a $100.!
A good wrap of duct tape should see those tyres good for a few thousand more miles.![]()
When I bought my Pickup, it had 20 year old Firestones on it. The tires only had about 1,500 miles on them, the spare had never been on the ground.
The vehicle had been out in the Southern California sun for most of those 20 years before I bought it, therefore, even though the tires had lots of tread, they also had lots of weather cracks in the sidewalls. The spare, however, had been encased in one of the tire covers and was/is still good as new.
Don't forget the black shoe polish (per Bert Munroe)!
