AM69

Transverse multi - intercept grooves and deep pattern depth.

Optimize the overall rigidity distribution of the pattern block, uniform distribution of grounding pressure design, directional pattern design.

Reduce the transverse width of the middle pattern, increase the design of the cylinder at the bottom of the groove of the pattern block, and increase the grounding force of the pattern block. In the early stage, it can be used as a driving wheel, and in the later stage, when the transverse groove is less, it can be used as trailer.
