Title:
MANUFACTURE OF PNEUMATIC TIRE AND PNEUMATIC TIRE
Document Type and Number:
Japanese Patent JP2000238148
Kind Code:
A
Abstract:
To provide a pneumatic tire having improved uniformity.
In a secondary molding step of manufacturing a raw tire, a strip-like rubber member 19 is wound twice on a BT drum 24 to form an annular top tread 20. As a result, the tread 20 has no fear of forming a gap in a circumferential direction, and no necessity of effectively connecting a connecting part of the member 19 by butting it. Thus, a weight of the connecting part can be suppressed to become a locally heavy, and uniformity of the tire can be improved.
