How Many Years Can Tires Generally Be Used?
2 Answers
Generally, passenger car tires should be replaced every 60,000 to 80,000 kilometers or every 3 to 5 years. However, relying solely on mileage or usage time to determine tire lifespan is insufficient; the actual condition of the tires should ultimately decide. Due to variations in driving environments, habits, and parking conditions, wear may occur earlier or later than expected. Here are methods to assess tire wear: 1. Check tire wear indicators: All tire brands have wear indicators in the tread grooves. When the tread depth wears down to the level of the raised wear markers, it's time to replace the tires. 2. Bulging: If the tread bulges, it indicates localized rubber deterioration or uneven pressure. Such tires are at risk of bursting and should not be driven on. 3. Cracking due to aging: If tires show extensive cracking, especially around the tread and wheel hub, it signifies severe aging and a high risk of blowouts, necessitating immediate replacement. 4. Sidewall punctures: Punctures in the sidewall are more serious than those in the tread. If the damage is near the wheel rim, where the steel wires are weaker, repairs may not be effective, so replacement is recommended. 5. Gaps exceeding 6mm: If tread damage or cracks exceed 6mm in depth, exposing the underlying fabric, repairs are futile, and replacement is advised.
I've been driving for over a decade and have changed four or five sets of tires. It's hard to say exactly how long tires last, but generally they should be replaced every five years or so. It really depends on how much you drive - if you're doing 20,000-30,000 kilometers annually, the tread might wear out in three to four years; if you only drive a few thousand kilometers a year, they could easily last six years. Rubber naturally deteriorates with age - I've seen seven or eight-year-old tires covered in cracks, looking like sun-dried tree bark. Last time, a mechanic taught me how to inspect tires: replace them when the tread depth is less than 1.6mm, and change immediately if there are bulges on the sidewalls. Winter driving especially requires paying attention to tire condition - safety always comes first.
