Abstract
The present invention relates an apparatus for deflating at least one tire of a vehicle including, an extendible tire deflating means attached to a housing, a plurality of biasing members adapted to urge the tire deflating means into an extended position, and a retraction means for withdrawing the tire deflating means into a retracted position within said housing, wherein in said retracted position the tire deflating means is held in place against the influence of said biasing members. The tire deflating means can be remotely extended and retracted, which ensures that the user can be positioned in a location where they are not in physical danger.
