Abstract
A method and apparatus for testing tires in a repeatable manner. Testing steps are performed in a manner that minimizes impact on the tire characteristics being measured. In one aspect, tire rotation reversal is performed at a zero crossing of a first harmonic of radial load variation exerted on a load carriage by the tire. In another aspect, load carriage retraction is performed so that the tire is unloaded when the tire stops rotating.
