ABSTRACT:
System for testing pneumatic tires. A tire that revolves under a load is deformed at the area in which it meets the roadway. Such a deformation results in the tire having an effective rolling radius that is shorter than the radius it has while static and/or unloaded. According to the invention, tires are tested by determining their effective rolling radii. When tires having similar effective rolling radii are used on an automotive vehicle, the undesirable torque steer effect is thereby reduced.
