Car Road Block

The roadblock spikes in this product are cone-shaped structures, which can be placed at will without adjustment. The sharp tip can quickly puncture the tire, and the air will be quickly released from it.
When the wheel touches the roadblock spike, due to the pressure during driving, the wheel presses against the tip of the roadblock spike, and the entire roadblock spike will pierce the tire in the direction of movement. The wheel continues to rotate, making the needle on the tire pierce deeper and deeper, and the gas in the tire will leak out from the roadblock spike. Within 30 seconds, all the gas will be released to effectively intercept the vehicle.
