How often should new car tires be replaced?
2 Answers
Car tire replacement mainly depends on mileage and years of use. Under comprehensive road conditions, tires should be replaced every 30,000-50,000 kilometers, or every 3-5 years. Below is relevant information: 1. Tires undergo prolonged friction with the ground, causing the rubber to age. When cracks appear on the tires, replacement measures must be taken to avoid potential safety hazards. It is recommended to have them inspected every six months after about 5 years of use. If the wear is severe and the balance feels off, replacement is necessary at this point. 2. Generally, tire dealers do not specify a clear time frame, but it is advisable to use them for at least three years, up to about five years. If the mileage reaches 30,000-50,000 kilometers, the tires should be replaced.
After driving for so many years, my experience tells me that replacing new car tires isn't about fixed timing—it mainly depends on wear and usage habits. The tread pattern is the key inspection point; when the depth is less than 1.6mm, it's time to change them, otherwise they can easily slip in rainy weather, posing safety risks. Tires are also affected by aging—even with low mileage, they may crack or deteriorate after 5 years. I make it a habit to check the tread depth every 5,000 km using a coin test and also pay attention to the production date marked on the tire sidewall. If you frequently drive long distances or on rough roads, wear accelerates, possibly requiring replacement in just 2 years. But for typical family cars, 4 to 5 years is a reasonable range. Before replacing, compare brands and cost-effectiveness—don't just go for the cheapest option, as safety comes first. Delaying replacement could lead to blowout accidents. Taking timely action helps avoid greater losses.
