After How Many Years Should Car Tires Be Replaced?

[OMaddox]

Car tires should generally be replaced every 3 to 5 years. Here are several situations when tire replacement is necessary: 1. Tires must be replaced when the tread groove depth wears down to 1.6mm, otherwise accidents may easily occur; 2. Replacement is required when the wear indicator bars (horizontal lines) on the tire shoulders become visible; 3. Tires need to be replaced after experiencing blowouts due to accidents or if bulges are detected. Whether tires need replacement should be determined based on three comprehensive factors: wear level, aging degree, and damage condition. Immediate replacement is necessary if any one of these factors fails to meet standards, ensuring driving safety. Tires often operate under complex and demanding conditions, thus requiring high load-bearing capacity, traction performance, and cushioning properties.
