Title:
TIRE
Document Type and Number:
WIPO Patent Application WO/2016/092755
Kind Code:
A1
Abstract:
Provided is a tire having a tread that exhibits both improved grip performance and wear resistance. In this tire, (LA - LB)/X is 0.277-0.350 where LA is the length of a perpendicular line drawn to a tire rotation axis P from the center position A of a tread surface in the width direction of the tire, LB is the length of a perpendicular line drawn to the tire rotation axis P from a position B separated from the center position A by one fourth of the peripheral length of the tread surface in the tire width direction along the periphery of the tread surface, C is the position of an orthogonal cross point where a perpendicular line drawn from position B meets the perpendicular line connecting position A with the tire rotation axis, and X is the length between position B and position C. The tire has a tread obtained using a rubber composition that contains 40-140 parts by mass of a silica-containing filler and 5-40 parts by mass of a low-softening-point resin having a softening point of 145˚C or lower with respect to 100 parts by mass of a rubber component containing a modified conjugated diene-based polymer.
