Description

  The present invention relates to a type of tire rupture prevention structure, and more particularly, to a structure that improves a tire to be a safe tire and that is compatible with various tire sizes and powers to ensure driving safety.

  Generally, tires are divided into those having an inner tire and high-speed tires having no inner tire. None of these tires can be prevented from being destroyed from the outside, and tires with inner tires form tension due to the filling of the inner tires, and the outer tires can be extended to run, but the tires are sharp. If it is stabbed with an object or blade, it will be destroyed and will not be able to run, and you will have to push the car. If tires are destroyed on the highway, an accident may occur. Also, high-speed tires do not leak immediately even if they are stabbed from the outside, and can save time for driving to a repair shop. However, because of the characteristics of high-speed tires, the driver overlooks the stab, and the lack of tire pressure is not significant, and the driver suddenly leaks while driving on the highway while neglecting the inspection, causing an accident There is a fear.

  The above-described drawbacks are expected to be improved. Therefore, the present inventor has provided a structure such as that of Patent Document 1 in order to improve this defect for some time.
