Patent ID: 8146636

Claim:
A pneumatic tire comprising a tread forming a ground surface comprising a non-conductive rubber composition, and a side wall adjacent to the tread comprising a non-conductive rubber composition, a cement rubber being applied to an outer surface of a tire from a ground region of the tread to a rim contact region of the tire to form a continuous coating film of a cement rubber, wherein the cement rubber comprises a rubber composition comprising: 100 parts by weight of a rubber component containing from 50 to 100 parts by weight of a diene rubber having a weight average molecular weight (Mw) of from 250,000 to 450,000, from 10 to 30 parts by weight of carbon black (A) having a nitrogen adsorption specific surface area (N 2 SA) of from 700 to 1,300 m 2 /g and a dibutyl phthalate (DBP) absorption of from 300 to 550 cm 3 /100 g, and a carbon black (B) comprising at least one carbon black selected from the group consisting of HAF, FEF and GPF grades, wherein the total amount of the carbon blacks (A) and (B) contained in the rubber composition is from 50 to 90 parts by weight per 100 parts by weight of the rubber component, the rubber composition being dissolved in an organic solvent.
