Look on the side of the tyre for the DOT code. It's two numbers, giving the week and year it was made, so, for instance, 1719 would be week 17 of 2019
It's not recommended to use tyres that are more than 5 years old as, even if they're not used, the rubber will harden and be more prone to failure.
A friend found this out when he bought a "new" tyre for his car out in Qatar, then it abruptly and catastrophically failed whilst he was doing about 60mph. Fortunately they were in a desert section, so there was plenty of run off!
It turned out, having looked at the DOT code, the tyre was something like 10 years old...
