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.
Claims6
A method of reducing the lateral force variation exerted by a pneumatic tire on its supporting surface comprising;
- determining the direction and position on the tire with respect to the circumference of the tire of the maximum lateral force exerted by the tire on its supporting surface during rotation of the tire;
- removing a larger amount of rubber from the radially outer surface of the axially outer rib of the tire on the side of the tire in the direction of the maximum lateral force at the area of maximum force than from any other area of said axially outer rib, determining the position on the tire of the maximum variation of lateral force from the maximum lateral force, and removing a larger amount of rubber from the radially outer surface of the other axially outer rib at the area of maximum variation from the maximum lateral force than from any other area of said other axially outer rib.
