A vehicle tire deflation device (10) comprises a base (12), a plurality of hollow vehicle tire deflating quills (14) removably secured to the base (12), and structure (16), including a curved portion and a flat portion, operably associated with the base (12), for positioning the device (10) in a tire penetrating orientation so as to penetrate a tire of a vehicle as the tire rolls over the device (10), upon the device (10) being positioned on a road surface adjacent the vehicle tire to be deflated in a non-tire penetrating orientation; such that the device (10) rolls on the curved portion from the non tire penetrating orientation and comes to rest on the flat portion in the tire penetrating orientation. The device (10) may include a member (22), operably associated with the base (12), for removably securing the quills (14) to the base (12), such that a rolling vehicle tire which embeds one of the quills (14) therein will cause the embedded quill (14) to sever the member (22) and separate from the base (12), the separated quill (14) thereby remaining in the tire as the tire rolls over the base (12). The device (10) may further have the quill inner diameter, the number of quills per unit length of base and the length of the base selected so as to deflate a vehicle tire within a predetermined distance ofrolling over the device.
