RUBBER COMPOSITION FOR TIRE SIDEWALL AND RUBBER INSERT COMPRISING SILICA WITH MANGANESE DIOXIDE CATALYST FOR DECOMPOSING OZONE AND THE TIRE USING THE RUBBER COMPOSITION

摘要

The present invention relates to a rubber composition for a tire wall and for a rubber insert, and a tire using the rubber composition. More specifically, the present invention relates to a rubber composition for a tire sidewall and for a rubber insert and a tire using the rubber composition, which is capable of decomposing ozone and which is environmentally friendly. The invention is characterized in that BET, which is used as a filler in rubber material, contains a relatively high silica containing manganese dioxide catalyst, and thus is capable of decomposing ozone, which is an environmentally problematic material.
