PNEUMATIC TIRE FOR PASSENGER CAR |
摘要 |
PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of further enhancing a road noise reducing effect by imparting a selecting width to a noise reducing means by clarifying a road noise generating mechanism. SOLUTION: This pneumatic tire for a passenger car satisfies a relational expression of f4<=fr<=(2×f5+f6)/3 or (2×f6+f5)/3<=fr<=f7 in a state of applying a standard load by filling air, assuming a primary resonance frequency of a cavity in a tier as fr and an n-order elastic mode frequency in the tire circumferential direction as fn.
