How many kilometers should tires generally be replaced?
1 Answers
Under normal circumstances, tires need to be replaced every four years or approximately every 80,000 kilometers. Tires are a crucial component of a vehicle, directly impacting driving stability and safety. How often tires should be replaced depends on specific conditions: If the vehicle is primarily driven on smooth urban roads with minimal usage and no tire damage, replacement can be done at around 80,000 kilometers or six years. For vehicles frequently driven on highways or rough terrain, tires should be replaced more often, typically every 30,000 to 50,000 kilometers or every four years. If significant tire wear, cracks, or bulges are observed, immediate replacement is necessary. The criteria for tire replacement mainly include the following: Time and mileage: This is the basis for most car owners to replace tires. For a typical private car driven mostly on smooth urban roads with occasional highway trips, the tire lifespan is relatively longer, and replacement can be done at around 80,000 kilometers or six years. Since tires are primarily made of rubber, prolonged exposure to air causes aging. Generally, after five years, tires begin to age, manifesting as hardened surfaces and cracks. Any external impact can cause these cracks to expand, leading to air leaks and potential blowouts. Therefore, even with minimal usage, tires should be replaced on time. Tire wear and abnormalities: If the remaining tread groove depth reaches or falls below 1.6 mm (indicated by wear markers in the longitudinal grooves), the tire must be replaced as its wet traction is significantly reduced, increasing the risk of hydroplaning. Regularly check tire pressure, as it is critical for tire performance. Tire pressure should neither be too high nor too low. Excessive pressure reduces tire grip, negatively affecting vehicle handling. Insufficient pressure can cause wave-like deformation, increasing the risk of blowouts. Always check tire pressure when the tires are cold for accurate readings. When purchasing new tires, always check the production date, as tires have a shelf life. Normally, unused tires have a three-year shelf life. Avoid buying tires older than three years, as prolonged storage can lead to aging.
