An apparatus for mounting a pneumatic tire in a testing and/or measuring apparatus comprises first and second mounting rim portions for holding a pneumatic tire between them in an inflated condition, on a rotatable spindle. The mounting rim portions are carried in concentric relationship with respect to the axis of rotation of the spindle, the first mounting rim portion being slidable in the axial direction on a guide. A clamp non-rotatably clamps the first rim portion to the guide along which the rim portion is displaceable in a released condition. The clamp includes a clamping element which is disposed about the axis and which is deformable upon inflation of the tire by the tire-inflation pressure to form a positively locking engagement between the first rim portion and the guide.
Apparatus for mounting a pneumatic tire to a rotatable spindle having an axis of rotation including:
Apparatus as set forth in claim 7 wherein said seal member provides sealing across the clearance space provided between said pressure ring and said guide member.
Apparatus for mounting a pneumatic tire on a device having a rotatable spindle with a rotational axis comprising first and second rim mounting portions, at least said first rim mounting portion being movable along said rotatable spindle in a direction substantially parallel with the rotational axis, at least one deformable clamp assembly positioned between said first rim mounting portion and said rotatable spindle so that when a tire is mounted between said first and second rim mounting portions and inflated, the inflation pressure activates said at least one deformed clamp assembly to non-rotatably clamp said first rim mounting portion and said rotatable spindle together.
