In a wheel assembly rotatably mounted to an axle of a mounting frame, an improvement comprising: two symmetrical hubs each including a first central hole having a central axis perpendicular to a rotational plane of said hub, said hubs being engageable with each other and forming a radial groove when engaged; and a tire including a second central hole with a central axis collinear with said first central hole central axis and perpendicular to a rotational plane of said tire, said tire disposed within said radial groove of said hubs; said hubs each including a first cylindrical surface, a first, second and third annular surface and an annular tooth disposed within said annular groove of said hub, said first and third annular surfaces parallel to said rotational plane of said hub, said third annular surface disposed farther than said first annular surface from said rotational plane of said hub, said second annular surface oblique to said rotational plane of said hub and interposed said first and third annular surfaces and said annular tooth interposed said first and second annular surfaces; said tire including a cylindrical surface contacting said first cylindrical surface of said hubs, a fourth, fifth and sixth annular surface and a first annular notch complementarily contacting said first, second and third annular surfaces and annular tooth of said hub, respectively, and a seventh, eighth and ninth annular surface and a second annular notch symmetrically disposed about said rotational plane of said tire and similarly complementarily contacting said symmetrically engaged hub; said tire including a plurality of holes radially diverged about and between said fourth and seventh annular surfaces of said tire, each hole having central axes parallel to said second central hole axis of said tire; said hubs each including a like number of holes as disposed and at said radius of divergence about and between said fourth and seventh annular surfaces of said tire, each hole having a central axis parallel to said first central hole of said hub; said hubs each including a second cylindrical surface which extends through said hub sufficient to accommodate a bearing assembly.
