PROBLEM TO BE SOLVED: To provide a rubber composition capable of suppressing the curing of rubber due to heat history such as running of a tire, and a tire using the same to realize excellent steering stability and vibration riding comfort from the beginning to the end of running. I will provide a. SOLUTION: The vulcanization accelerator is added in an amount of 0.5 to 100 parts by weight of a rubber component comprising at least one diene rubber. A rubber composition containing 5.0 parts by weight and 1.0 to 3.5 parts by weight of sulfur, wherein the total weight of zinc element contained in the rubber composition is in the range of 0.65 to 1.80 parts by weight. There is a feature. The zinc source of the zinc element is preferably at least one selected from the group consisting of zinc white, zinc carbonate, zinc dithiophosphates, and zinc dithiocarbamates. |
