Abstract
A composition useful for magnetic filled tires, particularly for tire sidewalls, which contains an organoxysilylsulfane coupling agent, is provided. The composition displays either improved fatigue resistance or either improved crack growth resistance or both. The sidewall composition is magnetizable to a magnetic field strength of preferably at least 0.1 Gauss, more preferably at least 0.5 Gauss, even more preferably at least 1 Gauss, even more preferably at least 10 Gauss, most preferably at least 25 Gauss, as measured at a distance of 8 mm for a 1 mm thick layer. The sidewall composition comprises 100 parts rubber, magnetic particulate, organosilane and curing agents. The compositions contain: curing agents in an amount effective to cure the rubber; such as sulfur preferably from 30 to 350 phr, more preferably from 40 to 300 phr, most preferably from 50 to 250 phr magnetic particulate; and preferably from 0.5 phr to 30 phr, more preferably from 1 to phr to 20 phr, most preferably from 2 to 10 phr organoxysilylsulfane. The present invention also relates to methods of making tires, and to the tire itself.
