TIRE COMPRISING A RUBBER COMPOSITION LAYER FOR INDICATING A LEVEL OF ABRASION, CAPABLE OF MAINTAINING THE PHYSICAL PROPERTY OF THE RUBBER OF A TREAD AND PROVIDING INFORMATION ON A LEVEL OF ABRASION OF A TIRE

摘要

PURPOSE: A tire comprising a rubber composition layer for indicating a level of abrasion is provided to maintain the physical property of rubber composition for a tread, providing different color from tread rubber by adding of dye and pigment. ;CONSTITUTION: A tire comprises a rubber composition layer(2) for indicating a level of abrasion. The rubber composition layer is installed in the tread block of the tire in different color from tread rubber. The rubber composition layer is located in at least one tread block in the circumferential direction of the tire. The rubber composition layer has a shape of triangle in cross section in the width direction of the tire, in which an area becomes narrow from the inner part of the tire toward the surface o the tread block. The rubber composition layer comprises dye and pigment of 5~40weight based on raw rubber of 100weight. The physical property of the rubber composition layer is similar to that of the tread block of the tire.;COPYRIGHT KIPO 2011
