The invention relates to a warm-up cycle for each tire being tested on a force variation machine to stabilize the measurement parameters and optimize the warm-up cycle. The method for cycling each tire comprises the following steps. A tire type and preset tolerance values for each parameter of the tire being measured is inputted into the force variation machine. The tire is rotated in a first direction for two successive revolutions, data values for each of the parameters are calculated, and the differences between the calculated data values and the preset tolerance values are determined. Then the tire is rotated in a second opposite direction and the warm-up cycle is repeated. Continuing, the tire is rotated for one or more additional revolutions and the data values for the measured parameters are again calculated if necessary. Next, the differences between the calculated data values for each corresponding parameter measured during successive revolutions after the second revolution and the preset tolerance values are determined until the difference between the corresponding data values for the parameters measured during any two successive revolutions is less than the preset tolerance values.
