How Often or After How Many Kilometers Should Tires Be Replaced?
2 Answers
Tires need to be replaced every four years, and it is recommended to replace them approximately every 80,000 kilometers. Precautions for tire replacement: The purchased tire specifications must first be consistent with the original tires equipped on the vehicle. The same axle should be equipped with tires of the same specifications, structure, manufacturer, and tread pattern. Tire replacement should comply with the manufacturer's recommendations: During replacement, the tire specifications must meet the vehicle manufacturer's requirements and recommendations. This means the load index of the replacement tire must be greater than or equal to that of the original tire, and the speed rating of the replacement tire must be greater than or equal to that of the original tire.
Tire replacement timing shouldn't be rigidly determined by mileage alone. With twenty years of driving experience, I primarily assess based on wear. Every tire has triangular wear indicators - when the groove depth reaches below 1.6mm, replacement is mandatory. Before my last long-distance trip, I noticed the front tires' inner edges were completely worn. A professional technician diagnosed it as misaligned wheel positioning. In rainy southern regions like ours, tires with poor drainage performance are especially prone to hydroplaning. For frequent highway drivers, I recommend inspections at 50,000 km, while city drivers might stretch to 60,000 km. However, note that tires older than five years will harden and crack regardless of tread depth. Once I discovered my sidewalls covered in craze cracks - the mechanic insisted on immediate replacement, warning they could blow out any moment.
