If a 50A tire made 3 years ago is tested again, does it test the same? Or does it test 54A? We know rubber hardens over time after being exposed to air. Rene Herse seals em away in plastic bags for this reason. We know car tire manufactures say not to use after 7yrs, irrespective of wear. What's the half life? Do we need markings on the wrapper saying when it was made? My coffee says when it was roasted. If you want north of $90 loonies for a single bicycle tire, should I be all Portlandia and ask for the mfg date to be made clear?
