（2）在充气压力、胎冠形状一定时，轮胎所受负荷越大，随下沉量的增大，接

（2）在充气压力、胎冠形状一定时，轮胎所受负荷越大，随下沉量的增大，接地印痕面积也就越大，并且接地面积与下沉量接近线性关系。
（3）在轮胎负荷、胎冠形状一定时，轮胎接地印痕面积随充气压力的提高，面积在不断减小。

結果 (英文) 1:

(2) air pressure, tread shape is constant, the greater load on the tires, with the increase of subsidence, larger footprint area, and ground contact area and sank close to a linear relationship.(3) the tire load, Crown shape when the tire footprint area with the increase of air pressure, decreasing in size.

結果 (英文) 3:

(2) in inflation pressure, tread crown shape must, tire load larger, with increase of subsidence, ground imprint area is also bigger and area and subsidence near linear relationship.
(3) in the tire load and tire crown shape must, tire contact footprint area decreases with the increase in the inflation pressure, the area is becoming smaller and smaller.
