Why don't tennis balls last long?
Tennis balls are designed to provide a certain level of performance, but their lifespan is limited due to a number of factors. The most significant is the abrasive nature of the court surface, which wears down the felt covering of the ball. Heat and humidity also have an impact, as well as the force of the shots and the speed at which the ball is travelling. Generally, a ball will last for between two and four hours of play before it needs to be replaced. To ensure the best performance, balls should be stored in a cool and dry environment and used regularly.
