Can a car tire with a small cut in the rubber be repaired?

[ORyder]

If a car tire has a small cut in the rubber but the cord layer is not damaged, it can be repaired. Below is relevant information about car tire damage: 1. Precautions: If a piece of rubber is missing from the tire sidewall, it is recommended not to repair it. Car tires are mostly radial tires, mainly composed of cord layers, steel belts, and rubber. The cord layers consist of transverse and longitudinal cords, whose main function is to bear the load, while the rubber's primary role is sealing and flexible deformation. The weakest part is the sidewall. If a repair is forced, the adhesive patch on the sidewall may fall off due to the constant deformation and recovery during rotation. If a mushroom plug repair is used, it may cause the sidewall cords to break, leading to bulging. 2. Explanation: A tire with sidewall damage can be temporarily used as a spare tire after repair, but long-term use is not recommended, and high-speed driving is not advised. When repairing a sidewall-damaged tire, the repair technician will also inform you of potential safety hazards and advise against long-term use. The sidewall of a tire is only protected by rubber material, unlike the higher protection strength of the tire's tread base.
