The invention provides a pneumatic tire which has a tread configured from a rubber composition containing 30-120 parts by mass of silica which has a BET specific surface area of 180-280 m<2>/g, per 100 parts by mass of a rubber component. When the negative rate in the contact width of the tread is 20-40%, improved wear resistance and wet grip performance are achieved, and a high degree of balance with a satisfactorily low rate of fuel consumption is achieved.
本发明可以提供一种充气轮胎,其具有由橡胶组合物形成的胎面,相对于100质量份的橡胶组分,所述橡胶组合物包含30至120质量份的二氧化硅,所述二氧化硅的BET比表面积为180至280m2/g,其中,当胎面的接地面宽度内的负比率为20至40%时,耐磨性和湿抓地性能得到改善,实现了与良好燃料效率的高度平衡。
