自上料攪拌車實心輪胎花紋的主要作用就是增加胎面和路面間的磨擦力，以防止自上料攪拌車車輪打滑，這與鞋底花紋的作用是一樣的。自上料攪拌車實心輪胎花紋提高了胎面接地彈性，在胎面和路面間切向力(如驅動力、制動力和橫向力)的作用下，花紋塊能夠產生較大的切向彈性變形。
The main function of the solid tire pattern of the self feeding mixer is to increase the friction between the tread and the road surface, so as to prevent the wheel slipping of the self feeding mixer, which is the same as the sole pattern. The solid tread pattern of the self loading mixer improves the contact elasticity of the tread. The tread pattern can produce large tangential elastic deformation under the action of tangential forces (such as driving force, braking force and lateral force) between the tread and the road surface.
切向力增加，切向變形就隨之增大，接觸面的“磨擦作用”也就隨之的增強，所以抑制了自上料攪拌車胎面和路面打滑或著打滑趨勢。
With the increase of tangential force, the tangential deformation increases, and the "friction effect" of the contact surface also increases, so the skid or slipping trend of the self loading mixer tread and road surface is restrained.
這在很大程度上，面消除了無花紋(光胎面)輪胎容易打滑的弊病，使得與輪胎和路面間磨擦性能有關的汽車性能——動力性、制動性、轉向操縱性和行駛安全性的正常發揮有了可靠的保障。
To a great extent, the tread eliminates the slip of the tread free (smooth tread) tire, and ensures the normal performance of the vehicle, which is related to the friction performance between the tire and the road, such as power performance, braking performance, steering maneuverability and driving safety.
有研究表明，中科自上料攪拌車產生胎面和路面間磨擦力的因素還包括有這兩面間的粘著作用，分子引力作用以及路面小尺寸微凸體對胎面微切削作用等，但是，起主要作用的仍是花紋塊的彈性變形。
Studies have shown that the friction force between the tread and the road surface of Zhongke self loading mixer also includes the adhesion between the two sides, the molecular gravity and the micro cutting effect of small-size bumps on the tread. However, the elastic deformation of the tread block still plays a major role.
