How to Check Tire Wear Level?
2 Answers
To check tire wear level, observe the thickness from the top to the bottom of the tread grooves. Tires need replacement when: 1. Exceeding service life or mileage limit; 2. Severe tread wear; 3. Abnormal tire pressure; 4. Significant tire cuts. Precautions for tire replacement: 1. Check production date - inventory shouldn't exceed 3 years; 2. Inspect tread pattern and color for abnormalities; 3. Ensure smooth transition between tread and sidewall; 4. Avoid mixing tires with different structures/sizes. Tire functions: 1. Support vehicle weight; 2. Absorb road shocks and vibrations.
I've been driving for over thirty years, and checking tire wear is second nature to me. Forget those fancy tools—the simplest method is using a penny. Insert the penny upside down into the tire tread. If you can see the entire national emblem on the coin, it means the tread is worn flat, and it's time to replace the tire. Before driving, I always walk around the car and feel the tire surface for uneven wear. For example, excessive wear in the center might indicate overinflation, while severe edge wear could signal suspension issues. Making this a weekly habit helps prevent accidents, especially since worn tires are prone to slipping in wet conditions and reduced braking performance. Regular tire rotation ensures even wear and extends tire life—I usually have them rotated at the repair shop every 5,000 kilometers. Developing this habit saves money and enhances safety.
