How many kilometers can a car tire run before needing replacement?

Car tires typically need replacement after running 80,000 kilometers. Here are specific details about tire replacement: Lifespan: The service life is generally set at 3 years. If a vehicle is driven 20,000 kilometers per year, replacement should be considered within 2-3 years. Spare tire: Even brand-new tires should be considered for replacement after 3 years of storage. Therefore, spare tires stored in the car trunk also require regular maintenance, and unused spare tires stored for too long should be renewed. Damaged tires should be promptly repaired and the spare tire should be switched back. Additionally, when changing to a spare tire, pay attention to adjusting the air pressure because there's usually a numerical difference between the spare tire's pressure and the tires in use. Before installation, use a pressure gauge to adjust it to the normal value for proper usage.
As a veteran driver with twenty years of experience, I believe tire replacement should be decided case by case. For regular family sedan tires, it's generally advisable to consider replacement after about 50,000 to 60,000 kilometers, but the key is to check the wear indicators. There are small raised blocks in the tread grooves - when the tread wears down to the level of these blocks, replacement is mandatory. Front tires typically wear faster than rear ones, so it's best to rotate them every 20,000 kilometers. Usage environment also matters - vehicles frequently driven on gravel roads or with frequent hard braking will wear tires faster. Last week I replaced my old tires after discovering fine cracks on the sidewalls - such tires need replacement even if the tread isn't fully worn. The safest practice is to routinely glance at your tire condition before driving - safety should never be compromised.
Tire lifespan is closely related to driving habits. I've noticed significant differences between my two cars: the daily commuter still uses its original tires at 80,000 km, while the mountain-road vehicle needed replacement at just 50,000 km. High summer temperatures accelerate rubber aging, making southern drivers particularly mindful of tire age. Even low-mileage tires over five years old require inspection as grip noticeably deteriorates. Modern tires display production dates on sidewalls - the last two digits of a four-digit code indicate the year. Maintain optimal pressure around 2.3 bar, as both overinflation and underinflation shorten tire life. If experiencing hydroplaning through puddles during rain, immediate inspection is crucial - safety always comes first.
