Title: Pneumatic tire
Inventor: ODA KAZUO
IPC: B60C9/18
Filed: 1984-04-05
Abstract: PURPOSE:To reduce the thickness of and the numbers of breaker cords by decreasing the angle between the breaker cord and the centerline in the peripheral direction of a tread so as to increase the strength of the breaker in the peripheral direction of a tread. CONSTITUTION:When the angle between a breaker cord and the centerline in the peripheral direction of a tread is taken as theta deg., the angle theta deg. is determined so as to satisfy the relation 0<=theta<=tan<-1>W/piD, where W: distance between both ends of a breaker cord; D: height of the breaker cord end. One or more layers of the breakers formed in the shape of one or more layers are divided into three parts: central, right, and left side parts, and the angle between thus divided each part and the centerline in the peripheral direction of the tread is set at theta deg. for the central part and 0 deg. for both the right and left side parts or in the reverse way. With this contrivance, unstable steering in driving a car, for example, can effectively be prevented.
