Description

Pneumatic tire having rim protector {Pneumatic tire having rim protector}

The present invention relates to a pneumatic tire equipped with a rim protector, and more specifically, the rim protector blocks and protects external shocks that may be applied to the sidewall and wheel of the pneumatic tire, and provides a standard rim of the wheel as well as an acceptable rim The present invention relates to a pneumatic tire equipped with a rim protector in which the pneumatic tire can be easily and accurately mounted according to the rim width of an allowable rim by manually pulling and opening the rim protector when the pneumatic tire is installed.

In general, the rim protector of a tire is already widely disclosed, and a detailed description thereof will be omitted, and reference may be made to Patent Publication No. 10-2018-0012532 entitled "Removable rim protector and tire having the same".

Meanwhile, the “detachable rim protector and tire having the same” includes a tire unit including a groove and a detachable rim protector mounted thereto, so that the user can selectively mount the rim protector according to various driving conditions. Accordingly, depending on the usage environment, the weight of the tire is reduced to improve fuel efficiency or to protect the tire unit from friction with the rim flange.

In addition, pneumatic tires are divided into rim protector types and general tires without rim protectors. In other words, the rim protector is manufactured with thick rubber to prevent damage to the rim that can occur in the low-end standard series. Accordingly, the rim protector not only protects the rim, but also plays a role in reducing the risk of tire damage from external shocks. And what these tires have in common is that among rims that are divided into standard rims and permitted rims, they must be easily mounted on standard rims as well as on permitted rims.

However, since pneumatic tires basically form a constant air pressure, there is a disadvantage in that they are vulnerable to sharp objects. Especially the sidewall part. As the thin rubber layer is the weakest part of the tire, there are also rim protectors made of thick rubber to prepare for and prevent external shocks. In addition, a tire that rolls without a rim protector has a disadvantage in that it continues to have a risk of breakage.

In addition, although a pneumatic tire can be easily mounted on the standard rim, it is difficult to mount the pneumatic tire on the allowable rim because the rim width is wide and it is difficult to locate the air inlet inside the bead of the pneumatic tire in the permissible rim. There is a disadvantage that their choice preference is low
