Also provided is a tire in which static ozone resistance, dynamic ozone resistance and discoloration resistance are highly balanced. The rubber composition comprises a rubber component, a petroleum wax, and an antidegradant, wherein the petroleum wax comprises a C20-C34 hydrocarbon component and a C35 or higher hydrocarbon component, and a proportion of the C20-C34 hydrocarbon component is 15% by mass to 30% by mass and a proportion of the C35 or higher hydrocarbon component is 70% by mass to 85% by mass, based on a total mass of the C20-C34 hydrocarbon component and the C35 or higher hydrocarbon component.",
