PNEUMATIC TIRE HAVING INNER LINER

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic tire which can reduce the road noise attributable to the tire vibration when a vehicle travels on a rough road, and improve the air impermeability of an inner liner. SOLUTION: The pneumatic tire has the inner liner consisting of a rubber composition in which >=40 mass % butyl rubber is contained in a rubber composition of 100 mass part, and hollow particles of the mean particle size of <=500μm are mixed so that the volumetric ratio is 2-40%. The hollow particles preferably have the strength that the ratio of breakage is <=40% at the hydrostatic pressure of 500 kg/cm<2> .
