Defect	For studless tires used in large trucks and buses, due to insufficient management of detection equipment in the manufacturing process, there is insufficient rubber adhesion to the steel material placed in the sidewall, and in some cases, the rubber thickness on the inner surface of the tire becomes thin. As a result, the sidewall may be damaged (bulging, cracking) during driving, leading to air leakage, and in the worst case, the tire may burst.
