A sulfur-crosslinkable rubber mixture includes from 40 to 100 phr of at least one natural and/or synthetic polyisoprene, and 15 phr or more of at least one hydrocarbon resin which is built up to the extent of 50 to 100 wt. % from aliphatic C5 monomers and to the extent of 0 to 50 wt. % from further monomers, where the hydrocarbon resin according to formula I) has a Q of from 0.015 [° C.·mol/g] to 0.050 [° C.·mol/g]. Formula I) is defined as Q=softening point [° C.]/centrifuge average Mc [g/mol]. In some aspects, the sulfur-crosslinkable rubber mixture includes 15 to 300 phr of the hydrocarbon resin, or even from 36 to 100 phr of the hydrocarbon resin. The further monomer(s) is or are selected from the group of unsaturated compounds, which can be polymerized cationically, which includes aromatics and/or unsaturated terpenes and/or alkenes and/or cycloalkenes.
