METHOD FOR DETERMINING CONCENTRIC MOUNTING OF A TIRE ON A WHEEL

摘要

Method for determining concentric mounting of a tire on a wheel. In one embodiment, method for determining concentric mounting of a tire on a wheel comprises: providing a tire including at least one bead area, wherein at least one rim centering tolerance indicator is oriented in the at least one bead area, and wherein the at least one rim centering tolerance indicator extends circumferentially about the tire; mounting the tire on a wheel to form a tire-wheel assembly, the wheel includes a circular cross-section including a center point; rotatably mounting the tire-wheel assembly on a tire balancing machine; providing a light source adjacent to the tire-wheel assembly, the light source projects a projected reference point upon the at least one bead area; rotating the tire-wheel assembly; and observing the runout of the projected reference point relative to the at least one rim centering tolerance indicator.
