Can Tires with Groove Cracks Still Be Used?
2 Answers
Tires with groove cracks cannot be used. Specific situations of tire cracks include: 1. If the tire shows signs of aging, with numerous small cracks at the bottom of the tread grooves or the tire sidewall that are close to damaging the tire body, it is necessary to replace the tire promptly. 2. If the remaining groove depth of the tire tread reaches or falls below 1.6 millimeters, the tire must be replaced. The tire's drainage capability decreases, increasing the risk of slipping on wet roads, and overly thin tires also pose a danger of blowouts during driving. Although tires that have been run underinflated can still be driven in an inflated state, the internal structure of the tire may have been damaged, so it is recommended to replace them with new tires promptly. Bulging tires should not continue to be used.
Noticing cracks in the tire grooves immediately put me on high alert. This is typically a sign of rubber aging, likely caused by UV exposure, dryness, or high temperatures. If the cracks deepen, the tire becomes brittle and loses elasticity, significantly reducing grip on wet roads and greatly increasing the risk of skidding or blowouts. Tires are the only part of the car that touches the road—if they fail, it's game over. My advice? Don't skimp on safety—replace those tires ASAP. Make it a habit to visually inspect tire surfaces and grooves weekly, especially if your parking spot is in constant sunlight, as UV protection is crucial. If your tires are over 5 years old, replace them regardless of crack size—new tires are a lifesaver.
