How many kilometers does a new car need to change tires?

Car tire replacement is influenced by various factors such as mileage, tire quality, road conditions, and driving style. Generally, tires should be replaced after about 60,000 to 80,000 kilometers for optimal performance. The service life and mileage of tires are usually only for reference. In actual use, car owners mainly judge whether to replace tires based on their specific conditions, with the tire surface tread being the most intuitive method. When the tread depth wears below 1.6 millimeters, the tire needs to be replaced. Severe tread wear significantly reduces the tire's grip and drainage performance, compromising safety, making the vehicle prone to skidding, increasing braking distance, and raising the risk of accidents. Some tires have wear limit indicators; when the tire wears down to the level of the indicator, it needs to be replaced. Tires that show cracks or bulges also need to be replaced promptly. Generally, these conditions indicate that the tire is damaged and poses a safety hazard. Avoid high-speed driving and replace the tire as soon as possible. Tire maintenance: During routine car maintenance, it is essential to develop good habits of checking, cleaning, and maintaining tires; avoid sudden braking or rapid acceleration that can burn the tires, and perform timely tire rotation to effectively extend tire life and potentially increase the mileage the tires can cover.

My car is only a year and a half old, but I know quite a bit about tires. There's no fixed mileage for when to replace tires on a new car—it mainly depends on your driving habits and the condition of the tires. For example, you can test the tread depth by inserting a one-yuan coin—if the coin covers the tread, it's time to replace them, as a depth below 1.6mm is unsafe. Additionally, tire aging plays a role; even with low mileage, tires can harden and crack after a few years, increasing the risk of a blowout. I recommend having them checked by a professional every 50,000 to 70,000 kilometers, but don’t rely solely on mileage—consider your driving habits too. If you drive mostly on highways, wear will be faster, while city driving may allow for slightly longer use. Safety comes first, and new tires can also improve fuel efficiency.

With over a decade of driving experience at my age, I've learned that replacing new car tires isn't just about mileage. A tire's lifespan is affected by multiple factors—driving on rough roads or frequent hard braking accelerates wear. Typically, every 60,000 kilometers is a checkpoint, but what matters more is checking the tread: if it's shallow or has small cracks, replacement is needed even at just 40,000 kilometers. Don't forget to inspect the tire sidewalls; when they age and lose elasticity, they're prone to blowouts at high speeds. I regularly visit maintenance shops for measurements to ensure my family's safety on the road. For new cars, you can hold off for the first three years, but reassess every five years or so after that.

Hi, I've been driving as a beginner for two years, and my friend taught me that whether to replace new tires depends on the actual situation. Mileage, like every 50,000-70,000 kilometers, is a reference point, but don't be rigid—you need to check the tires. For example, if the tread is almost worn out or small cracks appear on the surface, it's time to take action. For city driving, I make it a habit to measure the tread depth with a tread gauge every six months—the tool is cheap and simple. Money-saving tip: rotate the tires on time, swapping their positions every 10,000 kilometers to extend their lifespan. Don't compromise on safety; replacing them early saves trouble.
