A multiple use vehicle tire deflation device comprises a base, at least one cartridge removably secured to the base, and at least one vehicle tire deflating quill removably secured to the cartridge. The base, cartridge and quill are configured such that the quill, when imbedded by a vehicle tire rolling over the device, separates from the cartridge, whereas the cartridge remains secured to the base yet is readily removably replaceable. A replacement cartridge for a vehicle tire deflation device, which device includes a base, comprises a block, at least one tire deflating quill removably secured to the block, and structure on the block adapted to cooperate with the base of the tire deflation device to facilitate installation and removal of the block onto and from the base and to prevent the block from separating from the base when the quill becomes embedded in a vehicle tire rolling over the device.
