Tires of different dates, ok to use?
So I have an MPSS in brand new, great condition at home (no cracks, rubber looks "healthy") that was manufactured 43/13. Would it be unsafe to order just one new tire and run tires of different manufacture dates?

Going to piggyback off OP's question: Are rear tires of slightly different tread okay to use? Replaced one punctured tire with a new MPSS, now the rear tires have about 3mm tread difference. Is this okay long term? Should I fill up PSI slightly differently for the new tire?

rubber has a shelf life. performance degrades with time if that answers your question. if the tire has been kept indoors and out of the sun i'd say using it would be ok with a new tire.

No issues with that. Rubber does degrade, but I think the 5 year mark is where you'd want to think twice.

Should be fine as long as it's the same tire. The softer you go, the more you have to worry about time. But even then, if they are kept in large glad bags and in the garage you will be ok, but they can and do get harder as time goes by, but you might not notice unless you are tracking your car.

From Michelin website:
1- Keep five years in mind
After five years or more in use, your tires should be thoroughly inspected at least once per year by a professional.
2- Ten years is a maximum
If the tires haven't been replaced 10 years after their date of manufacture, as a precaution, Michelin recommends replacing them with new tires. Even if they appear to be in usable condition and have not worn down to the tread wear indicator.
This applies to spare tires as well.

Your tire is almost 4 years old already. If you were putting it on a Honda, I'd worry about long-term problems. For rear tires on a C63, there is no such thing as long term. I think you're good to go!

This is one of those cases where you'll get better info from a Google search - facts from Google almost always trump opinions from us!

Rubber compound stored properly is not going to degrade like it would if it was installed on a vehicle.

well...that's why i asked if it was indoors out of the sunlight.
even a tire that is not mounted has a recommended shelf life. something to do with leaching of chemicals causing the tire to harden and degrade over time. something like that.

10 yr is rubbish. 6 on an every day tire and max 5 on a HP tire.
Second, if you mix new with old with different tread pattern you could get squrrley performance and some surprises particularly in the wet or on track. Side wall spring rates will be different as the cords in the old tire have been flexing in the rubber.
Why take the chance for $300? Buy them at least in pairs.
