Title:
Pneumatic tire
Document Type and Number:
Japanese Patent JP6196494
Kind Code:
B2
Abstract:
To improve the rolling resistance and air resistance of a tire. It has a belt layer composed of two belt plies in which belt cords are obliquely arranged at mutually opposite angles θ with respect to the tire equator, and a band layer composed of a single band ply in which a band cord is wound spirally in the tire circumferential direction. The angle θ of the belt cords is in a range of 35 degrees˜55 degrees. When Wt is the tire cross sectional width (unit: mm), and Db is a bead diameter (unit: inch), the tire cross sectional width Wt satisfies the following expressions (1), (2). Wt=<−0.7257×(Db)̂2+42.763×Db−339.67 (1) Wt>=−0.7257×(Db)̂2+48.568×Db−552.33 (2)
