1 轮胎使用的“五要”( 1 )要按规定气压充气。若轮胎气压过高 ,则与地面接触面积减少 ,胎面易磨损 ,轮胎的缓冲力减弱 ,震动加剧 ,遇到较大撞碰时 ,甚至会引起爆胎 ,而且与地面附着力减小。若气压过低 ,轮胎易产生变形 ,滚动阻力增大 ,轮胎帘线容易脱层或折断 ,轮胎也易发热而 1 tire to use “five to” (1) to be inflated gas pressure. If the tire pressure is too high, then reduce the contact area with the ground, the tread is easy to wear, the tire damping force weakened, increased vibration, hit a larger collision, and even cause a flat tire, and with the ground to reduce adhesion. If the pressure is too low, the tire is easy to produce deformation, rolling resistance increases, easy to delaminate tire cord or broken, the tire is also easy to heat
