Wheel Parallelism: The wheels must

Wheel Parallelism: The wheels must be parallel two by two (those on the same basement) and then all four. The verification operation must take into account the differences in thickness that have been detected during the preliminary operations, which means that a preliminary average ideal thickness will be calculated and from time to time one will add or remove from the measurement taken half of the difference between the thickness real and really measured. Also in this case, if the measurements indicate that the tolerance is not respected, it will be necessary to loosen the bolts that fix the supports, position them so as to be within tolerance, then re-tension the bolts but only slightly.
