An automatic tire inflation/deflation system for a vehicle (10) is disclosed. Air passageways for the pressurize air are provided internally through the wheel assemblies without cutting into load bearing members. A rotating seal is provided by way of a pair of sealing rings (52, 54) located inboard of the hub bearings (32, 33) to protect the seals from adverse environmental conditions. A kit for retrofitting vehicles to include an automatic tire inflation/deflation system is also disclosed. Ramp surfaces (90, 91, 92) formed in the hub (30') are provided to facilitate removal of the bearing assemblies (32, 33). |
