An ejection device attaches to a push-bar of a first vehicle and deflates tires of a second vehicle. The device includes a housing, a propelling system, and a microprocessor. The housing is attached to the push-bar of the first vehicle, and contains at least one hollow triangular tube filled with sharp metal multi-directional spiked quills. The propelling system ejects the at least one hollow triangular tube filled with sharp metal multi-directional spiked quills out of the housing. The microprocessor controls a firing sequence of events to fire the at least one hollow triangular tube filled with sharp metal multi-directional spiked quills out of the housing.
