Do Tires Need to Be Replaced if They Have Cracks?
1 Answers
If there are minor cracks on car tires, determine whether they need replacement based on the following criteria: 1. Outer edge wear: If significant wear is observed on the outer edge of the tire when viewed in the direction of travel, it indicates the tire is frequently underinflated (insufficient pressure). 2. Convex and wavy wear: If the tread shows convex wear on both sides and wavy wear around the circumference, it suggests severe wear in components such as shock absorbers, bearings, or ball joints. 3. Even surface wear: If the wear has reached the standard tread depth (1.6 mm for tires narrower than 1.75 mm, or 2 mm for wider tires), replacement is necessary. 4. Inner tire wear: If the inner side of the tire is worn and the outer edges appear jagged.
