    I think Schwalbe at least stamps their tubes with the manufacturing date. I dimly recall seeing some white print on the inside of tyres as well.

    If the question is "am I right" or "is that correct" there's always some detail that makes the answer "no".

    Cars tend to spend more time outside where UV-light will affect the rubber. Bikes, at least most spend most of their lives inside for the benefit of the tyres

    60 months? That is 5 years. I have had several bikes where the tyres did stay on way longer than that. (Maybe fewer km, but that has nothing to do with age.) My folding bike of about 2002 is still using its first set of tyres and tubes.

    Grabbed a spare Bontrager R3 from the garage and it has “1152160617” printed in it. Possibly means “factory #11, machine #52, June 16th, 2017”, which is reasonable considering the date of purchase (mid-late 2019).
