Yes, tires do expire. Over time, the rubber degrades even if the tires are not used. It is generally recommended to replace tires that are over 6 years old, even if they appear to be in good condition. Check the DOT code on the tire's sidewall to find the manufacturing date. Proper storage and regular maintenance can extend their lifespan, but ultimately age will affect their safety and performance.
