Tyre age for trackdays (or in general)

[K20A2]

Looking forward to my first trackdays in the next weeks and I would like to ask for some advice, whether or not I should replace my tyres.

I have a set of AD08R and a set of A048.
I bought the AD08R in 2015 and the A048 in 2018.
All tyres were manufactured in 2014 though.

Would it make sense or be of advantage, if I already replaced them due to their age?

Many thanks
