All tires eventually begin to experience wear. How the tire wears can be a indication of an issue with your alignment or tire pressure. Tire tread should wear evenly across the whole tire rather than on the inside or outside of the tire. The wear on your tires will happen regardless of how good of a driver you are, although it can be accelerated if you don’t take proper care of the tires.
Tire aging occurs when components of the tire, including the rubber, begin to change over time. This can happen due to environmental impacts and storage conditions, as well as the amount of usage the tire sees when being driven, or the tire sitting with no use.
