  • Method of correcting conicity in a tire with a feedback loop
    Patent number: 6386945
    Abstract: A method for correcting the conicity value in a pneumatic tire with a feedback system based on the average conicity value as predicted by lateral forces measured during grinding is used in combination with correcting for lateral force variation, and/or radial force variation, and/or radial run-out variation characteristics of a pneumatic tire by grinding the tread surface. The correction of the conicity value is accomplished by grinding either of the shoulder regions of the tire tread.
    Type: Grant
    Filed: March 19, 1998
    Date of Patent: May 14, 2002
    Assignee: The Goodyear Tire & Rubber Company

  • Method of correcting conicity, radial run out, and force variations in a pneumatic tire
    Patent number: 5645465
    Abstract: A method for correcting the conicity value in a pneumatic tire based on the average conicity value is used in combination with correcting for lateral force variation, and/or radial run-out variation, and/or radial force variation characteristics of a pneumatic tire by grinding the tread surface. The correcting of the conicity value is accomplished by grinding either the shoulder regions of the tire tread or the central region of the tire tread.
