A patched tire can indeed be used normally and is suitable for highway driving. However, the method and location of the patch are crucial; if they do not meet the required standards, it could affect the safety of high-speed driving. Different manufacturers have slightly varying regulations regarding the speed limits for patched tires. Note: After a tire is repaired according to strict maintenance standards, its speed rating must be downgraded. The speed rating, indicated by a letter on the tire's sidewall, denotes the maximum speed the tire can handle. For example, in '225/15R1891V,' the letter 'V' signifies a maximum speed of 240 km/h. After patching, the rating should be downgraded from 'V' to 'H,' reducing the maximum speed to 210 km/h.
