1. A tire valve assembly for a tire mounted on a rim, comprising:
- a valve body coupled to the tire rim and having a valve sealing surface;
a valve sealing element disposed proximate to the sealing surface, anda biasing mechanism that controls biasing of the sealing element with respect to the sealing surface,wherein the sealing surface, the sealing element, and the biasing mechanism are disposed on the inside of the rim within the interior of the tire, andwherein the biasing mechanism includes at least one of a magnetic field, a remotely monitored electronic device, a remotely controlled electronic device, a remotely monitored electro-mechanical device, and a remotely controlled electro-mechanical device.

Abstract
A tire air pressure valve assembly is described that has an air sealing surface disposed toward or inside the metal wheel of a vehicle, and a protective housing surrounding a portion of the valve. The valve has an external stem with a built in break away feature which prevents external damage to the valve stem from damaging the sealing surface located inside the tire and wheel. The location of the seating/sealing surface inside the wheel, or inside a housing mounted on the wheel, provides protection from collision induced sudden tire pressure loss due to valve damage incurred during collisions or simply being struck by an object in a car wash or on the street.
