轮胎滚动阻力系数的大小取决于路面状况，柏油路为0.014~0.015，

轮胎滚动阻力系数的大小取决于路面状况，柏油路为0.014~0.015，软土道路为0.3~0.4。在平坦的路面上，克服路面变形和轮胎与路面的摩擦所耗用的能量仅占全部的10%~15%。不同道路的滚动阻力系数见表2-3。
当轮胎载荷和车轮扭矩增大时，轮胎径向和周向变形加大，滚动阻力也增加，特别是周向变形影响更大，如子午线轮胎虽径向变形大，但周向刚性大，故比斜交轮胎滚动损失小。轮胎在低速时对滚动阻力影响较小，但高速时，滚动阻力明显增加，当滚动速度高于轮胎径向变形在周围上的分布速度时，胎面的接地部分产生驻波，经受冲击负荷，胎体升温过高，胎面与帘布层间的附着力急剧下降，致使轮胎脱层爆破。
轮胎行驶到产生驻波时的速度，称为临界速度，以式（2-4）表示。

Size of tyre rolling resistance coefficient depending on the road conditions, the road was 0.014~0.015, soft dirt roads for 0.3~0.4. On a flat surface, overcoming the pavement deformation and tire and road surface friction and energy consumption accounted for by all the 10%~15%. Different road rolling resistance coefficients shown in table 2-3.When the tire load and wheel torque is increased, tire radial and circumferential deformation increase rolling resistance will increase, especially more circumferential deformation, such as radial tires are radial deformation, but rigid, so less than the tire rolling loss. Tyres at low speeds for less rolling resistance, speed, rolling resistance increased significantly when rolling faster than tires radial deformation around the distribution of speeds, tread the ground part of the standing wave, subjected to shock loads, body temperature is too high, fell sharply between tread and ply adhesion, tyre delamination blasting.The speed at which tires to produce standing waves, known as the critical speed in order (2-4).

The coefficient of rolling resistance depends on the road condition, the asphalt road is 0.014~0.015, the soft soil road is 0.3~0.4. On a flat surface, to overcome the friction of the tire and the road pavement deformation and the energy consumption accounted for only 10%~15%. The rolling resistance coefficients of different paths are shown in table 2-3.
when the tire load and wheel torque increase, tire radial and circumferential strain increase, rolling resistance increased, especially the circumferential deformation greater, such as radial tire although radial deformation is large, but week Xianggang high, so than the bias tire rolling loss. The tire has little effect on the rolling resistance at low speed, but the speed is high,Rolling resistance increased significantly, when the scroll speed higher than the tire radial deformation in the surrounding of the velocity distribution, the tread of the connecting part of a standing wave is generated and subjected to impact load, carcass temperature is exorbitant, tread and carcass ply interlayer adhesion decreased sharply, resulting in a tire delamination blasting. The speed at which the tire travels to a standing wave, called the critical speed, is represented by the formula (2-4).
