When Should Tires Be Replaced?
2 Answers
Tires should be replaced under the following circumstances: 1. When the tire wear reaches the 1.6MM mark, the tire needs to be discontinued; 2. Tread cracks, tread bulges, missing tread rubber, severe sidewall wear, or multiple punctures by foreign objects; 3. Tire surface hardening, cracking, or reaching the service life limit should prompt immediate replacement. Precautions for tire use: 1. Regularly inspect tires, especially before highway driving, ensuring to check tire pressure, sidewall cracks, and tread wear; 2. Periodically correct wheel balance, with the dynamic balance test value for a single side of the tire being less than or equal to 40 grams; 3. Regularly rotate tires, and avoid installing tires of different models or with significant differences in wear on the same axle.
Changing tires is something I have deep personal experience with, especially since I drive long distances frequently. Tire safety is literally a matter of life and death. When the tread is worn down to almost nothing, it's time to replace them. You can use a coin to measure the groove depth – if the national emblem is completely visible, that's a danger sign. In rainy conditions, braking distance can double and skidding becomes more likely. If there are cracks or bulges in the tire, replace them quickly as aged materials can easily blow out at high speeds, causing accidents. Uneven tire pressure leads to irregular wear, so check the pressure every two months to maintain balance. Even if rarely used, tires older than five years should be replaced as hardened rubber performs poorly. Don't forget to check the spare tire too, or you'll face bigger trouble in emergencies. I've made it a habit to regularly inspect these details while driving, saving on repair costs and avoiding unexpected risks, which gives me much greater peace of mind.
