摘要：
A pneumatic tire is disclosed having at least one component having a rubber composition including at least one diene based elastomer and a silica that prior to mixing with said elastomer is prehydrophobated with a fluorinated silane of the formula:
R f ― R 1 ― SiX 3-x ― R 2 x I
wherein R f is a perfluorinated group optionally containing one or more heteroatoms; R 1 is a divalent alkylene group, arylene group or mixture thereof, substituted with one or more heteroatoms or functional groups, containing 1 to 16 carbon atoms; R 2 is a lower alkyl group; X is a halide, a lower alkoxy group or an acyloxy group; and x is 0 or 1.
R f ― R 1 ― SiX 3-x ― R 2 x I
wherein R f is a perfluorinated group optionally containing one or more heteroatoms; R 1 is a divalent alkylene group, arylene group or mixture thereof, substituted with one or more heteroatoms or functional groups, containing 1 to 16 carbon atoms; R 2 is a lower alkyl group; X is a halide, a lower alkoxy group or an acyloxy group; and x is 0 or 1.
