Aroundnthe performance characteristics, especially the dynamic mechanicalnProperties of rubber compounds for vehicle tire treadsnTo improve, a vulcanizable rubber compound with anRubber content, one or more fillers and optionallynSuggested additives containing a special SBR rubber. For this purpose pointsnthe rubber content of the mixture is 1 to 100% by weight of an SBR rubbernwith a styrene content of 10 to 60 mol%, with a gradient over the chainsnof the rubber is distributed. The styrene units can be innmicro blocksnfrom 2 to 10 contiguous unitsnbe organized. The SBR rubber is adjusted so that thenMaximum of tan δ thatnexceeds the first maximum of the loss factor by at least 30 ° C. |
