How Often Should Bicycle Tires Be Replaced?
2 Answers
Under normal circumstances, the general lifespan of a tire is three years or 80,000 kilometers, although this depends on the condition of the tire. If the tread is not severely worn and there are no bulges, the replacement can be appropriately delayed. However, it should be replaced after about four years at most, as rubber will age. Below are some related details: Development of tires: The earliest tires were made of wood. Years later, rubber became widely used, and wheels gradually shifted from wood to hard rubber. Tire size: The traditional sizing system is based on the measurement of the tire's outer diameter. This method typically uses inches (26", 27", etc.) or millimeters (650, 700, etc.) as units.
I've been commuting by bicycle for almost a decade. The replacement interval for tires mainly depends on how frequently you ride. If you commute daily, averaging about 20 kilometers per day, I recommend checking them every six months. Monitoring the tread depth is crucial—when it's too worn, traction decreases, making it easier to slip in rainy weather. Also, replace them immediately if there are small cracks or bulges on the sides, as aging makes them fragile. Personally, I replace my tires every 2,500 kilometers, roughly once a year. Don’t forget to regularly inflate your tires, as low pressure accelerates wear. To extend their lifespan: choose tires suited for your riding surface—slick tires for smooth urban roads, and avoid rough gravel paths. Safety comes first; don’t skimp on costs, as delaying replacement can lead to accidents. Additionally, store them away from light and heat to prolong their usability.
