Abstract
The present invention relates to a pneumatic tire having a pair of spaced apart bead components, a connecting carcass between said bead components, and a rubber chafer positioned around at least a portion of each of said bead components and intended for contacting a rigid rim of a wheel, wherein said chafer comprises an outer skin layer intended for contacting the rigid rim and an inner core layer disposed radially inward of the skin layer.
Claims3
A pneumatic tire having a pair of spaced apart bead components, a connecting carcass between said bead components, and a rubber chafer positioned around at least a portion of each of said bead components and intended for contacting a rigid rim of a wheel, wherein said chafer comprises an outer skin layer intended for contacting the rigid rim and an inner core layer disposed radially inward of the skin layer wherein the inner core layer does not contact the rigid rim;
- wherein the outer skin layer is constructed from a rubber composition comprising from 50 to 75 phr of reinforcing carbon black and the inner core layer is constructed from a rubber composition comprising from 30 to 40 phr of reinforcing carbon black.
A pneumatic tire having a pair of spaced apart bead components, a connecting carcass between said bead components, and a rubber chafer positioned around at least a portion of each of said bead components and intended for contacting a rigid rim of a wheel, wherein said chafer comprises an outer skin layer intended for contacting the rigid rim and an inner core layer disposed radially inward of the skin layer wherein the inner core layer does not contact the rigid rim;
- wherein the outer skin layer is constructed from a rubber composition consisting of
- 100 phr of at least one rubber containing olefinic unsaturation;
- from 50 to 75 phr of reinforcing carbon black;
- at least one additive selected from the group consisting of sulfur donors, accelerators, retarders, oils, resins, tackifying resins, plasticizers, silica, ultra high molecular weight polyethylene (UHMWPE), pigments, fatty acids, zinc oxides, waxes, antioxidants, antiozonants, peptizing agents, and sulfur containing organosilicon compounds;
- and
- the inner core layer is constructed from a rubber composition consisting of
- 100 phr of at least one rubber containing olefinic unsaturation;
- from 30 to 40 phr of reinforcing carbon black;
- and
- at least one additive selected from the group consisting of sulfur donors, accelerators, retarders, oils, resins, tackifying resins, plasticizers, silica, ultra high molecular weight polyethylene (UHMWPE), pigments, fatty acids, zinc oxides, waxes, antioxidants, antiozonants, peptizing agents, and sulfur containing organosilicon compounds.
