Abstract

Provided are a pneumatic tire having extremely excellent on-ice performance, and a rubber composition for tire treads used to prepare the pneumatic tire. A rubber composition for tire treads, based on 100 parts by weight of diene rubber, the rubber composition contains 0.5 to 15 parts by weight of non- Metal fiber, 0.5-30 parts by weight of eggshell powder, and a pneumatic tire containing the rubber composition for tire tread.

Description

technical field [0001] The present invention relates to a rubber composition for tire tread and a pneumatic tire containing the rubber composition. Background technique [0002] When driving on icy and snowy roads, studded tires are generally used, and chains are mounted on the tires, but cause environmental problems such as dust formation; therefore, studless tires have been developed as tires for running on icy and snowy roads instead of the above tires. [0003] Since ice and snow roads have a significantly lower coefficient of friction and slippery compared with ordinary roads, it is necessary to invent and design materials for studless anti-skid tires. For example, rubber compositions incorporating diene rubber and having excellent properties at lower temperatures have been developed. In addition, attempts have been made to improve the friction performance on ice (ice performance), etc., by changing the unevenness on the tire surface to...
