How to Identify Good or Bad Tire Quality?
3 Answers
To determine if a tire has been retreaded, check if the tread exhibits a natural blue hue without fingerprint marks, which indicates it meets quality standards. If both sides of the tire's contact area show convex wear patterns with wavy peripheral wear, this suggests severe wear in components such as the shock absorbers, bearings, and ball joints of the vehicle.
When assessing tire quality, I usually start with the daily driving experience. If a new car feels excessively bumpy or noisy on rough roads, it often indicates the tire hardness is inappropriate. High-quality tires tend to be more flexible and quiet. By touching the tread, good rubber material feels fine and elastic, not stiff like hard plastic. I regularly check tread depth – when it's below 3mm, it's time to replace them, otherwise, they may skid dangerously in rainy conditions. I also pay attention to brand reputation; established brands like Michelin and Bridgestone are generally reliable. However, don't just focus on price; cost-performance is crucial, and choosing the right size for your vehicle model is even more important. In the long run, good tires can last two to three years without issues. During maintenance, remember to rotate tire positions regularly and check tire pressure to ensure even wear and avoid blowout risks. Safety always comes first.
I judge tire quality primarily based on safety performance. If there are cracks or bulges on the tire sidewalls, it indicates rubber aging or manufacturing defects, and immediate replacement is necessary without delay. Measuring tread depth with a coin is simple and accurate: insert a one-yuan coin, and if the top of the national emblem is visible, the depth is only 3mm left. Test drive a short distance in the rain; during emergency braking, the stopping distance should be short, and there should be no skidding for a reliable tire. Good tires have strong grip, making the car stable as a rock during high-speed turns. In terms of brand selection, well-known brands like Dunlop or Goodyear are generally trustworthy, and a mid-range price is sufficient—don't skimp and buy counterfeit products. Every time you wash your car, take a moment to check tire pressure and wear symmetry, as these directly affect braking effectiveness and accident risk.
