摘要
The present invention relates to a cross-linkable rubber composition, a cross-linked rubber composition obtained by cross-linking such a rubber composition, a method of preparing a tyre and a tyre. In a cross-linkable rubber composition the cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): ≥1 phr to ≤99 phr of a rubber component selected in from the group of styrene-butadiene rubber (SBR), polybutadiene rubber (BR), natural rubber (NR) or a mixture thereof; and ≥1 phr to ≤120 phr of an aliphatic resin component. The composition further comprises ≥1 phr to ≤50 phr of a polyisoprene rubber (IR) having ≥mol-%, as determined by NMR spectroscopy, of 3,4-linked units derived from isoprene. It has surprisingly been found that such a polyisoprene rubber having 3,4-linked units derived from isoprene in combination with aliphatic resin worked very well in broadening the tan delta curve of the compound, indicating the compound can perform well in wide range of conditions when cured and used as a rubber for a tyre tread.
