Type and Size of Tire

The type and size of tire that circulates in the market, continue to change in various ways every era. The mainstream bias tire of earlier 1970s inch notation in Japan, was also often seen those of tube tires by wheel. Since the 1980s shifted to the radial tire of the most metric notation, tube tire almost disappeared. The boundary of the late 1980s that brake regulation has been strengthened in the light car, I began to migrate to the radial tire 12-inch size from the tire 10-inch size. 

 

Tires on written standards also called metric notation only if inch notation exists, but actually genuine adopted example is negligible, or even there are many almost no size. You can no longer new automobiles adopted in recent years in this transition, disappear from the only tire market distribution of adopted size to a small part of the vehicle type, or often a problem such as the type of tire is extremely narrow, which can be selected occur.
