How Often Should Private Cars Replace Tires?

[Peggy]

Household car tires generally need to be replaced every 3-5 years, although this timeframe is not fixed and depends on specific driving conditions. For normal driving, tire replacement can be categorized by time or mileage. Here are the details: 1. Time-based replacement: Tires are made of rubber, and rubber products degrade over time, typically within about 5 years. This means that when a tire reaches 5 years from its manufacturing date, it should be replaced promptly for household cars. 2. Mileage-based replacement: As you drive, the tread of the tire gradually wears down. When the wear reaches a certain level, the tire needs to be replaced. This can be determined by the wear indicators on the tire, which are located via small triangular marks on the tire sidewall. When the tread pattern aligns with the wear indicator, it signifies that the tire's braking performance, handling, and other functions have deteriorated. Continuing to use such a tire poses significant safety risks, so immediate replacement is necessary.
