Abstract
A method of reducing the lateral force variation exerted by a rotating pneumatic tire on its supporting surface, which method comprises mounting the tire on a rotatable rim, inflating the tire to a preselected pressure, urging the tire against a load roll with a preselected force, rotating the tire to determine the lateral force variation, grinding the axially outer rib of the tire on the side of the tire in the direction of the maximum lateral force at the point of the maximum lateral force and grinding the other axially outer rib at the point of maximum variation from the maximum lateral force.
