PROBLEM TO BE SOLVED: To exhibit high grip performance since a travel initial time.SOLUTION: A pneumatic tire 2 for driving wheel, and a pneumatic tire 3 for non-driving wheel comprise a tread part 4 respectively. The tread part 4 has plural spherical projections 6. Each of the projections 6 has maximum width of 3.0-7.0 mm and height of 1.0-4.0 mm, and an interval L between adjacent projections 6 is 1/7-1/3 of tread width Tw. The interval L1 between projections 6 provided on the pneumatic tire 2 for driving wheel, is larger than the interval L2 between projections 6 provided on the pneumatic tire 3 for non-driving wheel.SELECTED DRAWING: Figure 2
【課題】走行初期から高いグリップ性能を発揮する。【解決手段】駆動輪用の空気入りタイヤ2及び非駆動輪用の空気入りタイヤ3は、それぞれ、トレッド部4を有し、各トレッド部4には、複数の球面状の突起6が設けられる。各突起6は、3.0〜7.0mmの最大幅と、1.0〜4.0mmの高さとを有し、隣接する突起6の間隔Lが、トレッド幅Twの1/7〜1/3である。駆動輪用の空気入りタイヤ2に設けられた突起6の間隔L1は、非駆動輪用の空気入りタイヤ3に設けられた突起6の間隔L2よりも大きいものとした。【選択図】図2
