Can a tire still be used if there is a cut on the sidewall?

[SanEmilio]

Tire sidewall damage is recommended to be replaced promptly. Because the sidewall of the tire is relatively weak, if the sidewall is damaged, it is almost impossible to repair. Continuing to use it poses a risk of tire blowout and safety hazards. Conditions requiring tire replacement: From the perspective of tire usage timeline, the sidewall of the tire will have a four-digit number indicating the manufacturing date of the tire, with the first two digits representing the week and the last two digits representing the year. Generally, tires should not be used for more than 3 years or exceed 60,000 kilometers in mileage. Although slightly exceeding the time and mileage may not be a major issue, the low temperatures in winter and rainy conditions in summer can significantly reduce the tire's wet grip and dry handling performance. Pay attention to the tire sidewall: As the tire rubber gradually ages, deep cracks may appear on the sidewall. However, as long as the sidewall has not been impacted and the cords are not broken, the tire can continue to be used. The triangular mark on the tire sidewall can help the owner locate a protrusion in the tread groove to determine the actual wear limit of the tire, which should be greater than 1.6 millimeters. Daily precautions: Increase awareness of tire safety. Regularly inspect tires, especially before driving on highways. Conduct thorough and detailed checks, including not only tire pressure but also observing whether there are cracks on the sidewall and the condition of tread wear. Address any potential hazards promptly. Regularly correct wheel balance. Excessive wheel imbalance can cause high-frequency vibrations at high speeds, leading to uneven tire wear and compromising driving safety. After tire repair, dynamic balance testing and adjustment should be performed. The single-side dynamic balance test value should be less than or equal to 40 grams. Regularly rotate tires. To ensure even wear on all tires of the same vehicle, perform tire rotation every 5,000 kilometers and wheel alignment every 5,000 to 10,000 kilometers to avoid abnormal excessive tire wear. Do not install tires of different models or with significant differences in wear on the same axle.
