Can small cracks on car tires be left without replacement?
2 Answers
Small cracks on the surface of car tires do not require replacement. Here is relevant information about tire cracks: 1. Causes: Mostly due to poor maintenance. Or driving on gravel roads or construction sites, where hard objects come into contact with the tires, causing damage to the inner layers under heavy pressure. 2. Lifespan: Theoretically, the effective lifespan of tires is three to four years, but actual replacement mileage can vary depending on driving conditions and frequency. However, tires are after all rubber products, and even with the addition of carbon black, they will gradually age due to environmental influences. Molecular structure may undergo invisible changes that can affect tire performance.
As someone who frequently researches car maintenance, I believe small cracks on the tire surface don't necessarily require immediate replacement, but it depends on the specific situation. These small cracks usually result from rubber aging, such as oxidative hardening caused by prolonged exposure to sunlight. The key is to check the depth of the cracks: if they are only shallow surface lines and don't expose the inner cord layer, the tire can still hold up for a while. However, if the cracks feel deep when pressed or are located on the tire sidewall, the risk of a blowout increases significantly. I recommend checking your tires monthly by gently scraping them with your fingernail to test the depth, while also ensuring the tire pressure is standard—insufficient pressure can accelerate crack deterioration. Tires generally last 4 to 6 years, and even if they appear intact beyond this period, it's advisable to consider replacement, especially before long trips. For the sake of your family and yourself, don't take risks to save money—getting a free inspection at a reputable shop is a safer bet.
