To provide a pneumatic tire unit which can achieve rolling resistance, wet brake performance, and wet drive performance in a well-balanced manner.SOLUTION: A tread part 20 of a pneumatic tire 10 has: wet emphasizing compounds 26 where different compounds 25 are arranged in a shoulder area Sh and a center area Ce and which are the compounds 25 where tan δ at 0°C is within 0.80≤tan δ(0°C)≤1.10; and low rolling compounds 27 to be compounds 25 where tan δ at 60°C is within tan δ(60°C)≤0.15. In a front tire 11, the wet emphasizing compounds 26 are arranged in the shoulder area Sh and the low rolling compounds 27 are arranged in the center area Ce; in a rear tire 12, the low rolling compounds 27 are arranged in the shoulder area Sh, and the wet emphasizing compounds 26 are arranged in the center area Ce.SELECTED DRAWING: Figure 2
