Everyone has heard horror stories on the news about aging tires and safety blow outs, so how can YOU tell how old your tires are? The week and year of manufacture are stamped on the side wall of the tire. We can liken a aging tire to an aging rubber band, the elasticity breakdown and the rubber begins to crack. Tires do not have a specific "expiration" date, although 7 years is an industry breaking point. It is suggested to check the tires thoroughly throughout their lifespan.
