ABSTRACT:
A pneumatic tire having improved wet traction has lugs containing sipes which change direction within the lug and tie bars in the sipes near each point where the sipes change direction. Siping, and the positioning of tie bars, provide means for minimizing the difference of the principle direction of lug stiffness between individual lugs. Also, a tire of the invention has 4 pitch ratios which are distributed around the tire so that extra large pitches are not located next to small pitches.
