Abstract: The present disclosure relates to a hydrogenated petroleum resin and a rubber composition including the same. The hydrogenated petroleum resin according to the present disclosure not only improves the viscoelastic properties of rubber containing the same, but also has excellent compatibility with rubber, thereby improving the overall physical properties of the rubber. Thus, rubber molded articles manufactured from the rubber composition containing the hydrogenated petroleum resin, for example, tires, have improved grip strength (wet/dry) and reduce an increase in rolling resistance due to the improvement in grip force to simultaneously satisfy two properties of grip force and rolling resistance required as a tire, thereby manufacturing a low-fuel consumption and high-performance tire.
