Abstract
The present invention provides a rubber composition for a tire capable of improving gripping performance of a tire and a tire using the rubber composition. More specifically, the present invention relates to a rubber composition for a tire tread comprising 1 to 150 parts by weight of a piezoelectric material, based on 100 parts by weight of a natural rubber and/or a diene synthetic rubber and a tire using the rubber composition for a tire tread. The average particle size of the piezoelectric material is preferably 0.01 to 50 μm.
