PROBLEM TO BE SOLVED: To provide a pneumatic tire having enhanced abrasion resistance while improving grip performance on a road face in any temperature range or condition such as dry road face, wet road face and on ice and snow road face at good balance.SOLUTION: There is provided a pneumatic tire having a tread manufactured by using a rubber composition having total weight of a filler of 70 pts.mass or more based on 100 pts.mass of a rubber component, where the content of a styrene-butadiene rubber in 100 mass% of the rubber component is 30 to 70 mass%, the content of carbon black is 40 pts.mass or more based on 100 pts.mass of the rubber component and rubber physical properties after vulcanization of the rubber composition has hardness at -10°C (Hs) of 69 or less, tanδ at 0°C when conducting viscoelasticity measurement at initial strain of 10% and dynamic strain of 2% of 0.50 or more and tanδ at 30°C of 0.20 to 0.27 and glass transition temperature (Tg) of -35°C or less.SELECTED DRAWING: None |
