Patent ID: 7531596

Claim:
A tire having a component comprised of a rubber composition comprised of a diene based elastomer composition which contains a N-1,3-dimethylbutyl-N′-phenyl-p-phenylene diamine antidegradant (6-PPD) and further contains a dispersion of methyl isobutyl ketone (MIBK)-absorbing particulate activated carbon; wherein said MIBK-adsorbing activated carbon is comprised of a microcrystalline, non-graphitic form of carbon having an average specific surface area determined by nitrogen adsorption of from about 500 to about 2000 m 2/ g and wherein at least 50 percent of the total pore volume of said isobutylene-adsorbing activated carbon is comprised of pores having a pore width of from about 1.8 to about 50 nm, wherein said component is an outer, atmospherically exposed sidewall rubber layer, wherein said rubber composition further contains methyl isobutyl ketone (MIBK), as a by-product of said 6-PPD, and wherein at least a portion of said MIBK is adsorbed by said MIBK-adsorbing activated carbon in situ within the rubber composition.
