An apparatus for mounting and demounting a tire on and from a rim of a vehicle wheel. The apparatus comprises at least one fitting or removal tool for mounting and demounting the tire, and a control unit for controlling movement of the fitting or removal tool. A load measuring device measures the load applied on the tool while mounting or demounting the tire. A counterpart method comprises moving the fitting or removal tool towards or away from the vehicle wheel for mounting or demounting the tire to and from the rim, capturing the load applied to the tire by the fitting or removal tool, calculating the load applied to the tire by the fitting or removal tool while mounting or demounting the tire, and controlling movement of the fitting or removal tool on the basis of the load applied to the tire by the tool.

Apparatus and method for mounting and demounting a tire to or from a rim of a vehicle wheel

A brake test stand for testing vehicle brakes and for determining the brake forces acting on the respective vehicle wheel. The brake test stand comprises first and second pairs of rollers for positioning the two wheels mounted on a common axis of a vehicle thereon, wherein the rollers of each pair of rollers are arranged opposite to each other and the pairs of rollers are provided side by side. A control unit controls the test stand. First sensing devices are positioned respectively below and between the rollers of each pair of rollers for sensing the pattern of the running surface of each of the tires of the wheels mounted on the common axis. A processing and calculation unit processes the data obtained by the first sensing devices for calculating tire conditions based on a correlation of the data of the coaxially mounted tires.
