Title:
PNEUMATIC TIRE FOR MOTORCYCLE
Document Type and Number:
WIPO Patent Application WO/2005/018959
Kind Code:
A1
Abstract:
A pneumatic tire for a motorcycle increased in cornering stability, comprising carcasses (1) locked, in a loop back form, around bead cores (3) buried in a pair of bead parts (2), tread parts arranged on the outer peripheries of the crown parts of the carcasses (1), and a pair of side wall parts extending from both ends of the tread parts in the radial inner direction of the tire. The pneumatic tire is characterized in that the bead cores (3) are of the cable type, and the coefficient of geometrical moment of inertia ∑ (&pgr /64 × d4)(where d indicates the diameter of each filament forming the bead core 3) of the bead cores (3) meets the requirement of the following equation, 0.50 <∑ (&pgr /64 × d4) < 1.50.
