The present disclosure provides a rubber mixture and a tire made the same. The rubber mixture consists essentially of: at least one kind of polar or non-polar rubber, at least one kind of filler, at least one kind of vulcanizing agent, at least one kind of accelerant, an optional anti-scorching agent, and an optional aromatic material. The accelerant is a compound containing two or more X-Y single bonds, wherein X is selected from element O and S, and Y is selected from element N and P. The rubber mixture and the tires of the present disclosure adopt improved accelerants and anti-scorching agents to reduce the generation of pungent volatile organic compound such as aniline, cyclohexylamine, tert-butylamine, and imine, thereby improving the odor problem of the tire. Meanwhile, the present disclosure omits carbon black, zinc oxide and other substances with fine powders, thereby reducing dust hazards to the operators.
