Pneumatic tire wheel assembly for tracked vehicle

A pneumatic tire wheel assembly (4) for tracked vehicles (1) has a unique rim assembly (8) for dual wheel mounting. The rim assembly has a pair of annular rims (6) connected by a plurality of laterally extending spokes (10,20 or 30). The spokes (10,20 or 30) enable mud and debris to pass preventing the accumulation of debris, mud, or snow between the wheel and the track.
