摘要： A carbon black reinforced rubber composition which contains hydrophilic sorbitan monostearate and specialized tackifying resin and a pneumatic rubber tire having a visually observable rubber component, such as for example a rubber sidewall, of said rubber composition. The surface of said rubber composition, namely the tire sidewall rubber component, in its uncured state contains said hydrophilic sorbitan monostearate on its surface together with said specialized tackifying resin to promote enhanced building tack and thereby counteract building tack loss by the sorbitan monostearate having been exposed to moisture (moisture exposed surface) during the processing of the rubber composition, particularly after its high shear processing such as, for example, extrusion.

摘要： The invention relates to a tire having a rubber tread comprised of cap/base construction where the tread outer cap rubber layer contains the running surface of the tread and the tread base rubber layer underlies the tread cap layer wherein the base layer provides a transition zone between the tread cap layer and the remainder of the tire carcass and is not intended to be ground-contacting. For this invention, the tread base rubber layer is comprised of three distinct zones, namely a circumferential annular central rubber zone positioned between two lateral annular rubber zones. In one aspect, the rubber tread cap layer and zoned rubber tread base layer are co-extruded together to form an integral tread rubber composite.

摘要： A racing tire comprising a tread having a new tread thickness of no greater than about 0.375 inch. The tread defines a running surface that includes a first circumferential portion of a first rubber compound and a second circumferential portion of a second rubber compound situated adjacent one another. The first rubber compound has a greater stiffness than the second rubber compound so as to provide the tread with greater wear resistance along the first circumferential portion, and the second rubber compound provides the tread with greater traction along the second circumferential portion. The tread may be substantially free of a tread pattern. The second rubber compound may have a greater DIN abrasion value than the first rubber compound. The second rubber compound may have a higher tan delta at 100° C. and/or a higher J″ traction value than the first rubber compound.
