The invention provides universal ultralow-rolling-resistance tire crown rubber. The universal ultralow-rolling-resistance tire crown rubber is prepared from natural rubber, N134 carbon black, silicon dioxide, a super silane coupling agent, zinc oxide, stearic acid, sodium alkyl dithiocarbamate, fatty acid zinc salt, microcrystalline wax, an anti-aging agent 4020, an anti-aging agent RD, a maleic anhydride derivative, novolac epoxy resin, oil-extended sulfur and an accelerant NS. The invention further provides a preparation method of the universal ultralow-rolling-resistance tire crown rubber. The invention further provides a universal tire with ultralow rolling resistance. According to the invention, single rubber and reinforcing agents with similar particle sizes are used, the defect of material compatibility in the formula is eliminated, a new reaction crosslinking mode is innovatively introduced, a vulcanization crosslinking network structure is enlarged and extended, the deformation loss modulus of the crosslinking network is reduced, and ultralow tire rolling resistance performance is realized. The industrial internal mixer production method is innovatively designed, the production efficiency is improved, and tire vulcanization defects are eliminated.
