Document Type and Number:
Japanese Patent JP2752435
Kind Code:
B2
Abstract:
PURPOSE:To prevent both the wear in the rim-flange contacting part and the separation between a carcass and a rubber layer providing a cushion rubber, between the coating rubber layer for coating an up-carcass and a down-carcass and the rubber layer forming the outermost layer of a tire, whose loss tangent and 100% modulus have a prescribed relationship with those of both the above rubber layers. CONSTITUTION:The 100% modulus value MC of a carcass coating rubber 34 for coating an up-carcass 12 and a down-carcass 16 is set to have a value of 40 to 65kg/cm<2>. And, the 100% modulus value MG of the rubber chafing rubber 36 forming the outermost layer of a radial tire 10 being in contact with the rim flange is set to have a value of 25 to 35kg/cm<2>. Further, a cushion rubber 38 is interposed between both rubber layers 34 and 36. The loss tangent tandelta of this rubber 38 is made less than that of the rubber layer 36, and the 100% modulus value MK thereof is set to satisfy the relational expression MC>MG= MK. By this constitution, both the wear in the outermost layer and the separation between the carcass and the rubber layer can be prevented.
