Abstract: A dolly assembly rotatably supports and enables roller positioned placement of a tire. The dolly assembly comprises three C-shaped frames, two roller assemblies, and wheel assemblies. The C-shaped members each comprise opposing support arms and a framing span. The roller assemblies each comprise an inner support span and a cylindrical roller member. The cylindrical roller members are rotatable about the inner support span axes. The inner support span joins the support arms of the first and second C-shaped members. The support arms of the first and second C-shaped members are adjustably mounted to and supported by the support arms of the third C-shaped member. The roller assemblies function to rotatably support a tire. The wheel assemblies are cooperatively associated with the third C-shaped member for enabling roller movement relative thereto.
