Abstract: An effective production method for silane-treated clays having exceptional reinforcing effects with respect to rubber, and compositions using these silane-treated clays are offered. With the silane-treated clay production method, a functional silane is predispersed or emulsified in water by means of a surfactant in order to mix the functional silane with kaolin clay and thereby uniformly surface-treat the kaolin clay with the functional silane. The surfactant should preferably be a non-ionic surfactant with an HLB value in the range of 8-18. The silane-treated clay formed by surface-treating kaolin clay by means of these functional silanes characteristically contains low residual levels of the non-ionic surfactants. The functional silanes can be either vinyl or sulfur functional silanes. The silane treated clays are useful as fillers or extenders in rubber compositions, particularly those employing silicas and/or carbon blacks.

Abstract: A vehicle tire having a rotation time wear indicator associated with the tire tread which visually shows when the tire tread has worn to various levels at which levels the tire should be rotated to a different wheel position on a vehicle. The wear indicator is a plurality of pattern parts such as holes, raised portions in tread grooves or other distinctive patterns in the tread which are positioned at various radial levels of the tread with the different levels being spaced apart at different locations around the circumference of the tread. When the tread wear reaches various levels relative to the levels of the pattern parts, so that any particular pattern part is no longer visible, then it is time to rotate the tire to another wheel position.
