The invention belongs to the technical field of tires, and particularly relates to a performance-balanced strong wet grabbing tire pattern which comprises a longitudinal main groove and an inner middle pattern block, the inner middle pattern block is provided with a plurality of cutter grooves, the cutter grooves are transversely arranged and are inclined at a certain angle, and the angle range is 45-75 degrees; at least one end of the cutter grooves is connected with the longitudinal main groove; a tubular channel is arranged at the bottom of the cutter grooves; at least one end of the tubular channel is communicated with the longitudinal main groove; and a radial pipeline is also arranged in the cutter grooves and is connected with the tubular channel and the surface of the inner middle pattern block. The problems that in the prior art, the wet slippery performance is improved only from the angle of drainage, and the improvement effect is low are solved, the water storage volume is increased through multiple design schemes, the drainage speed is increased, the water film cutting capacity is improved, and the wet slippery performance of the tire is greatly improved; besides, the groove depth does not need to be increased in the pattern design, the control stability, rolling resistance, noise, abrasion and the like are fully considered, and the tire performance can be more balanced.

    本发明属于轮胎技术领域,具体涉及一种性能均衡的强湿抓轮胎花纹,包括纵向主沟和内中花纹块,内中花纹块上设有若干个刀槽,刀槽为横向设置并倾斜一定角度,角度范围为45~75度;刀槽至少一端与纵向主沟相连接;刀槽底部设有管状通道,管状通道至少一端与纵向主沟相连通;刀槽内还设置有径向管道,径向管道连接管状通道与内中花纹块表面。本发明克服了现有技术只从排水角度改善湿滑性能,改善效果低的问题,通过多种设计方案增加储水体积,加快排水速度,增加切水膜能力,大大提升了轮胎湿滑性能;另外,本发明的花纹设计不需要增加沟槽深度,充分考虑了操控稳定性、滚阻、噪音、磨耗等,能够使轮胎性能更加均衡。
