Tripod Casters Casters Casters Wholesale expansive one: at a certain load and driving conditions, truck tires have a proper tire pressure, tire pressure below the standard value when driving, the tire radial deformation increases, excessive scratching on both sides music, so tread both sides of the ground, the side wall tire pressure, tire side wall tension, tire cord body have a greater deformation and alternating stress. Cyclic deformation, fatigue will be back to speed cord damage, so that ply tire and the relative slip between the tire and the ground increases, increase the heat generated by friction, the tire temperature to rise sharply reduce the tensile strength of the rubber , loose cords and local delamination in case of disorder generated by the shock on the tire. Uneven tread pressure, so the shoulder part of the badly worn tire, a "bridge effect", the tread was dentate or wavy. Easily embedded in the tire tread recess road nails and stones, causing mechanical damage. Matrix to increase rolling resistance, fuel consumption increases. Tests showed that when tire pressure falls below the standard value of 20% -25%, 20% corresponding increase in fuel consumption. When the tire pressure is higher than the standard value when driving, so tread central ground, tire and road contact area decreases, the load per unit area increased, the central tread wear and tear. Tire cord was over-done, stress increases carcass cord, cord fatigue, speed up the process, causing cord to pull off, resulting in an early tire puncture. 

 II: In a certain load and tire pressure, the speed increases, the tire deformation frequency, and carcass of the tire circumference and the lateral vibration of distorted (the formation of stationary waves) increases, the unit of time the heat generated by internal friction increases , tire work performance, even tread ply cracking and spalling, accelerated tire wear and damage. 

 Tripod Casters Casters Casters Wholesale expansive three: in certain tire pressure, tire deflection to increase overload, cord and cord stress increases, could easily lead to tire wall parts of the cord to break loose and ply delamination, carcass cord of the force will exceed the design allowable stress and tire contact pressure, the heat increased, carcass temperature, carrying capacity decreased. At the same time due to shoulder contact with the ground produces tire wear, especially in the face of obstacles, even if a small stone, can cause fetal crown burst. Practice has proved that, in turn, and driving on uneven road conditions, when the tire load of more than 20%, the mileage will be reduced 35%; more than 50%, the reduced 59%; more than 100 times, reduced 80%. 

 Four: the road conditions on the life of the tire a great impact, it affects the situation of the tire and the friction with the ground by the tire dynamic load
