I've listed a set of tires for sale:
A prospective buyer has asked the manufacturing date of the tires, which I see is 1704 rear 2604 front, meaning they are 6 years old.
The tires came off of my new-to-me 929, are at least at 80% - 90% still, and the po had the tires put on 2 years ago. Their manufacturing date is news to me as I hadn't thought to look.
Now I'm nervous to sell a tire that old, as I don't want to give someone something that may not perform as advertised, but I can't find anything on Metzeler's site specifically talking about shelf life of their tires.
So do I bin them, or are they worthy for more road use?
