    摘要： The present invention relates to a run-flat tire employing a rubber composition capable of improving processability without reducing the durability during run-flat traveling. More specifically, the present invention relates to a run-flat tire comprising a bead filler 7 and a pair of side-reinforcing rubber layers 8. At least one of the bead filler 7 and the side-reinforcing rubber layer 8 employs a rubber composition obtained by adding 3 to 10 parts by mass of sulfur and 0.1 to 30 parts by mass of a low-molecular-weight conjugated diene-based polymer (B) having a weight average molecular weight in the range of 2,000 to 10,000, to 100 parts by mass of a rubber component (A) containing at least a natural rubber or polyisoprene rubber and having a weight average molecular weight in the range of 150,000 to 2,000,000.

    摘要： A reduced oil rubber composition includes (a) a silica filler, (b) a N-substituted polyalkylene succinimide derivative, and (c) a rubber matrix. In certain embodiments, the composition may comprise a reduced amount of oil, especially a reduced amount of aromatic oil or even no aromatic oil. Rubber articles manufactured from such composition, such as tires and power belts, have improved properties such as reduced rolling resistance, improved wet/snow traction and winter softness, improved dynamic stiffness, improved tensile strength, easy handling, and/or compatibility with higher environmental standard, among others.
