According to the mileage driven, tires should be replaced approximately every 80,000 kilometers. Generally, the service life of tires is 6 years. The mileage and road conditions vary, and driving habits differ, so even for the same car model, tire wear levels will vary. Below are relevant details: Excessive wear: Long-term abnormal tire pressure or frequent driving on poor road conditions can lead to excessive tire wear. Typically, the service life of tires is 6 years, but due to differences in mileage, road conditions, and driving habits, tire wear levels will inevitably vary. If the tire wear is severe, immediate replacement is necessary. 1.6mm at the groove bottom: Looking from the triangular indicator towards the tire surface, when the tread wears to 1.6mm from the groove bottom, the groove will start to crack, showing obvious signs. When checking by yourself, you can use a key for comparison. If the groove depth is close to the key's thickness, it's time to replace the tire.

I often drive long distances, so I pay special attention to my tires. There's no fixed mileage for tire replacement—it depends on wear and tear. For sedan tires, it's time for a check-up after about 50,000 to 60,000 kilometers, while SUV tires might need attention even sooner. The key is to look at the wear indicators in the tire grooves; if those raised blocks are worn flat, it's dangerous. I check my tires every month: removing stones, inspecting sidewall cracks, and measuring tire pressure. Even if the mileage isn't high, tires can age after five years, and the increased braking distance after rain is especially alarming. Last time, my neighbor's tire blew out on the highway because of an unnoticed sidewall bulge. My advice? Don't delay—replace them when they reach the safety limit. Life is more important.

As a seasoned driver, I believe tires are like shoes—when they're worn out, it's time to replace them. For regular city commuting, driving 70,000 to 80,000 kilometers is normal. But it depends on the usage scenario: tires used for daily construction site trips will wear out much faster than those used for school runs. When my car hit 40,000 kilometers, I noticed the tread depth was down to just 1.6 mm, so I replaced all the tires immediately. Both overinflated and underinflated tires accelerate wear, so I make it a habit to check the pressure with a gauge every month. Winter snow tires require extra attention, as their grip on icy surfaces deteriorates rapidly. Don’t hesitate to replace tires that have been patched more than three times—they can be dangerous at high speeds.

My car has been driven for five years and 70,000 kilometers. During maintenance, I noticed fine cracks all over the tire surface. The mechanic said rubber naturally ages and must be replaced after six years, even if the car is parked in the garage without moving. The tire sidewall has a production date code – a four-digit number like 1523 indicates the tire was produced in the 15th week of 2023. Normal tires lose about 30% of their grip after five years of use, making rainy-day skidding particularly dangerous. Remember to get regular wheel alignments – unevenly worn tires might be ruined by 30,000 kilometers.
