ABSTRACT:
A pneumatic control apparatus and method controls gas pressure inside a tire (40) mounted on a wheel (32) which rotates about the centerline of an axle (30). A bleeder valve (28) is mounted on a body coaxially aligned with the axle centerline and is in fluid connection with a pneumatic fitting (23) on the tire. The bleeder valve allows gas inside the tire to be relieved to the atmosphere when the gas is above a set pressure. The coaxial alignment of the bleeder valve with the axle centerline permits the bleeder valve to relieve gas pressure unaffected by centrifugal forces.
