Car tire/tyre manufacturers stamp the date of manufacture on the tyre. The idea is apparently that the rubber starts to deteriorate from that date, regardless of whether it has been installed. After a certain number of months (60, typically?), the tyre is considered no longer fit for use.
It appears that manufacturers do not stamp bike tires with the date of manufacture, neither on the tyre itself nor on the sticker label; is that correct?
This is not too surprising given that many bike tyres are cheaper than car tyres and they tend to not last as long too, so 60 months start to look like an eternity for a bicycle tire. However, it becomes a bit puzzling when looking at studded mountain bike tyres (which often cost more than a car tyre) and studded fat bike tyres (which cost nearly three times the price of a car tyre).
- The convention may be quite different for rim strips.
