Title: TIRE
Abstract:
The present invention provides a tire that uses a resin material and still has improved ride comfort, improved dry handling performance, and favorable fuel consumption performance, without losing wet performance. The tire is characterized by comprising an annular tire skeleton body (10); a reinforcing layer (20) that is provided to the outside of the tire skeleton body (10) in the radial direction of the tire; and tread rubber (30) that is provided to the outside of the reinforcing layer (20) in the radial direction of the tire. The reinforcing layer (20): is a resin composition that includes 50-100 mass% of a resin material; and coats a reinforcing member (21). The storage modulus (E'0℃) of the tread rubber 30 at 0℃ and a strain of 1% is 30 MPa or lower, the loss tangent (tanδ0℃) thereof at 0℃ and a strain of 1% is 0.5 or lower, and the value (tanδ30℃-tanδ60℃) of subtracting the loss tangent (tanδ60℃) thereof at 60℃ and a strain of 1% from the loss tangent (tanδ30℃) thereof at 30℃ and a strain of 1% is 0.08 or lower.
