PROBLEM TO BE SOLVED: To provide a tire, particularly for use under a heavy load, which is controlled of reduction in hardness and is improved in reducing heat build-up and in wear resistance by improving the processability and productivity of a silica-filled rubber composition without deteriorating the physical properties and by improving a natural rubber in the prevention of reversion. SOLUTION: The tire is made by using as its member a rubber composition containing 100 pts.mass of a rubber component (a) comprising at least one rubber selected from natural rubber and synthetic diene rubbers, 3-50 pts.mass of silica (b) heat treated with a silicone oil, and 0.1-5.0 pts.mass of a hydrazone compound (c).
