The invention relates to a truck tire design method, and particularly relates to a design method and an application of durable groove bottom patterns of a truck tire. According to the design method ofthe durable groove bottom patterns of the truck tire, a tire pattern groove adopts a rounding design, and judgment is carried out by adopting a coefficient K. When the K is greater than or equal to 0.9, alpha+beta is greater than or equal to 20 degrees and less than or equal to 40 degrees, and r is greater than or equal to 2, a risk of groove bottom cracking is small. When the K is greater than or equal to 0.56 and less than 0.9, alpha+beta is greater than or equal to 22 degrees and less than or equal to 39 degrees, and the r is greater than or equal to 2, the risk of groove bottom cracking is small. And when the K is less than 0.56, alpha+beta is greater than or equal to 20 degrees and less than or equal to 40 degrees, and the r is less than 2, a probability of groove bottom cracking isvery high.
本申请涉及本发明涉及一种载重轮胎设计方法,尤其涉及一种载重用轮胎耐久沟底花纹的设计方法及其应用。一种载重用轮胎耐久沟底花纹的设计方法,所述的胎花纹沟采用倒圆设计,该方法采用系数K进行判断,当K≥0.9时,20°≤α+β≤40°时,r≥2,沟底裂的风险小。当0.56≤K<0.9时,当22°≤α+β≤39°时,r≥2,则沟底裂的风险小。当K<0.56时,此时20°≤α+β≤40°,r小于2,则发生沟底裂的概率很大。
