How often should tires be replaced under normal conditions?
2 Answers
Under normal conditions, tires should be replaced every 3 years. If the vehicle is driven 20,000 kilometers per year, replacement should be considered every 2 to 3 years; if it's driven around 10,000 kilometers annually, replacement should be considered every 4 to 5 years. Tires are often used in complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during operation. Therefore, they must possess relatively high load-bearing capacity, traction performance, and cushioning properties. Car tires are one of the crucial components of a vehicle, directly contacting the road surface and working in conjunction with the suspension system to mitigate shocks encountered during driving, ensuring good ride comfort and smooth operation.
I've been driving for over twenty years, and there's no one-size-fits-all rule for tire replacement—it mainly depends on usage. If you frequently drive on highways or long distances, you might need to replace them every 40,000 kilometers. For city commuting with less driving, every three to five years is also fine. The key is to regularly check the tread depth; if it's less than 1.6 millimeters, replacement is mandatory—that's the safety threshold. I also check tire pressure monthly to ensure it's within the recommended range, as over- or under-inflation accelerates wear. Cracks or bulges on the tire sidewalls are warning signs—don't wait until there's a risk of a blowout. Climate matters too—tires age faster in humid areas. Overall, safety comes first. Spending a little to avoid big trouble is worth it. I make it a habit to do a quick check every season for peace of mind. Remember, when buying new tires, choose reliable brands—don't skimp on safety to save money.
