Should tires be replaced if they have cracks?
2 Answers
Tires with cracks are recommended to be replaced promptly. If cracks appear due to wear on the outer edges, it can affect driving safety. For safety reasons, it is advisable to replace the tires to avoid the risk of a blowout while driving. Tire Introduction: Tires are rubber products that are exposed to the elements year-round, which inevitably leads to aging. They gradually lose their original elasticity and toughness, resulting in small cracks, which is a normal phenomenon. Tire Replacement Recommendations: The typical lifespan of a tire is about five years. After around three years of use, small cracks may appear. If the cracks are minor and located on the tread of the tire, they are considered normal aging cracks or wear and may not require immediate replacement, but regular inspections are still necessary. If cracks appear on the sidewall, it is essential to have them checked at a service center promptly and replaced if necessary, as the sidewall is the most vulnerable part of the tire. Continuing to drive with such cracks could lead to a blowout. If the cracks are too long or deep, reaching the standard tread depth of 1.6 millimeters, replacement is also required.
As a seasoned veteran in car maintenance, I believe tire cracks don't necessarily require immediate replacement—it depends on the specific situation. There are various types of cracks, such as those on the tread or sidewall. Sidewall cracks are the most dangerous because that area is thin and prone to blowouts while driving. During my own tests, I insert a coin into the crack—if it's deep enough to expose the edge of the coin, then replacement is definitely needed. Tire aging is usually the main cause, especially for tires over five or six years old, as the rubber hardens and cracks multiply. Regular driving on gravel roads or prolonged exposure to intense sunlight accelerates this process. Don't forget to check the tire's production date by looking at the DOT code on the sidewall. Safety first—if there's an issue, don't delay; visit a professional shop to have the tire inspected with specialized equipment for added security. In short, don't panic at the first sign of a crack, but stay vigilant, especially during high-speed driving, where risks are greater. Regular tire maintenance, including maintaining proper pressure and rotation, can extend lifespan and reduce problems.
