What is the service life of car tires?
2 Answers
Car tires have a service life of approximately 5 years or 80,000 kilometers. Detailed methods to extend tire service life are as follows: 1. It is recommended to rotate tire positions every 10,000-20,000 kilometers, as front tires wear more severely than rear tires. Rotating front and rear tires ensures more even wear. 2. Pay attention to checking tire pressure and maintain it around 2.2-2.5 bar. In winter, temperature drops can cause tire pressure to decrease, so it's advisable to inflate tires promptly during winter. 3. Try to park the vehicle in shaded areas to reduce damage from sunlight and UV radiation to tire rubber.
I've been repairing cars for ten years, and tire lifespan is really unpredictable. Some people need to replace them after three years, while others can last five. The key is checking wear – I always tell car owners to inspect tread depth; if it's below 1.6mm, replace immediately. Poor road conditions accelerate wear – daily gravel roads will definitely take a toll. If the tire sidewall cracks, don’t hesitate, just replace it. Rear tires wear slower, so rotate them regularly to balance wear. Don’t believe those who say tires must be replaced after a set number of years – I can tell at a glance whether they need replacing or not. New tires typically have a five-year shelf life, and older stock tires lose performance. Humidity in the south speeds up aging, so watch for cracks and delamination.
