All new tires have the date of manufacture stamped on the sidewall. It might be in some form of code. There is a chance you could buy tires that were made several years ago and I wouldn't think that would be a good thing if you were planning to keep the tires a long time.

It's going to be hard for me to change out my front tires in 10 years when they have plenty a tread on them. I wish I could swap front and back tires for an afternoon. That would fix the "excessive tread on an old tire" problem!
