Should I Replace the Tire if There Are Cracks on the Outside?
2 Answers
Whether to replace a tire with cracks on the outside depends on different situations: 1. If the cracks appear on the sidewall, replacement is necessary to avoid tire blowouts; 2. If the cracks are too long or deep, reaching the standard tread depth of 1.6 millimeters, replacement is required. The reasons for cracks on the outside of the tire are: 1. Natural aging of the tire; 2. The tire has been impacted. Precautions for using car tires include: 1. When inflating the tire, reduce the tire temperature to normal levels to avoid affecting pressure judgment; 2. Inflate to around 2.5 bar; 3. Regularly check the wear level of the car tires; 4. Avoid exposing the tires to high temperatures.
I've always been concerned about tire safety, especially when I see cracks on the outside. Tire cracks can be caused by aging, UV exposure, and prolonged use. Ignoring them significantly increases the risk of a blowout during high-speed driving, which could lead to an accident. I first check the location and depth of the cracks. If there are cracks on the sidewall or they're deep enough to expose the cord layer, the tire must be replaced immediately. Even if the surface appears intact, tires older than six years should be regularly inspected, as aging weakens their overall strength. When parking, I try to avoid direct sunlight to extend their lifespan. Safety always comes first—while replacing tires isn't cheap, it's nothing compared to family safety. Making it a habit to visually inspect tire condition monthly, including cracks, pressure, and wear, can reduce accidents and ensure peace of mind while driving. This applies to every car owner.
