<p>A method of and an apparatus for testing a tire comprising mounting the tire on a rotatable spindle, applying a load to a tire perimeter with a moveable load carriage by moving the load carriage into contact with the tire perimeter, rotating the tire and measuring one or more tire parameters as a function of the tire's rotational position, determining a desired tire stop position, determining a retraction distance that will be traveled by the load carriage to unload the tire, determining a retraction time required for the load carriage to move the retraction distance, calculating an angle of rotation that will occur during the retraction time, deducing a tire retraction position at which retraction must begin such that the load carriage will complete retraction at the desired tire stop position, and beginning load carriage retraction at the tire retraction position.</p> |
