  • Undercut tie bar for pneumatic tire
    Patent number: 6631746
    Abstract: A pneumatic tire includes a tread having a plurality of spaced tread blocks separated by grooves or slots. A plurality of tie bars extend across the grooves or slots between adjacent tread blocks. The tie bars have a pair of sidewalls and a top surface with an undercut formed in at least one of the sidewalls to reduce tie bar stiffness and provide increased water evacuation as the tread wears. The top surface of the tie bar is lower than the top surfaces of the adjacent tread block and the undercut can be formed in only one or both sidewalls of the tie bar and have various stepped and tapered configurations.
