Document Type and Number:
WIPO Patent Application WO/2016/157906
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a tire having satisfactory braking performance on dry road surfaces and wet road surfaces, and having excellent maneuvering stability. To accomplish this purpose, the present invention is a tire provided with a tread 10 made using a rubber composition in which the tan δ at 0°C is 0.25-0.55, the difference between the tan δ at 30°C and the tan δ at 60°C is -0.02-0.07, and the dynamic storage modulus at a dynamic strain of 1% and a temperature of 0°C is 4-20 MPa; the tire characterized in that the tread 10 has circumferential grooves 20 extending in the tire circumference direction C, the negative ratio in the grounding surface is 15-25%, the negative ratio occupied by the circumferential grooves 20 is 8-14%, and the negative ratio occupied by grooves other than the circumferential grooves 20 is 7-11%.
