This invention reveals a pneumatic tire having an outer circumferential tread wherein said tread is a sulfur-cured rubber composition comprised of, based on 100 parts by weight of rubber, (1) from about 5 to about 50 parts of 3,4-polyisoprene rubber, wherein said 3,4-polyisoprene rubber has (a) a 3,4-isomer content of from 75 percent to 95 percent, (b) a 1,2-isomer content of from 5 percent to 25 percent, (c) a glass transition temperature from 0.degree. to 25.degree. C. and (d) a number average molecular weight which is within the range of 30,000 to 180,000; and (2) from about 50 to about 95 parts of a rubbery polymer which is co-curable with the 3,4-polyisoprene rubber. The subject invention further discloses a pneumatic tire having an outer circumferential tread wherein said tread is a sulfur-cured rubber composition comprised of, based on 100 parts by weight of rubber, (1) from about 20 to about 60 parts of natural rubber, (2) from about 5 to about 30 parts of high cis-1,4-polybutadiene rubber, (3) from about 10 to about 50 parts of styrene-butadiene rubber, and (4) from about 5 to about 30 parts of 3,4-polyisoprene rubber, wherein the 3,4-polyisoprene rubber has (a) a 3,4-isomer content of from 75 percent to 95 percent, (b) a 1,2-isomer content of from 5 percent to 25 percent, (c) a glass transition temperature from 0.degree. to 25.degree. C. and (d) a number average molecular weight which is within the range of 30,000 to 180,000.

Incense burner

An incense burner device adaptable for use in a vehicle such as an automobile. It includes an open ended container for burning incense. A stem extends from the closed end which is removably fitted into the sleeve of a clamp device for supporting the container upright. The clamp device is attachable to a component member of an automobile such as the edge of an ashtray. The ashes of the incense are discharged into the ashtray by removing the container from the sleeve connector and upending it into the ashtray.
