  • Patent number: 7096150
    Abstract: A method and apparatus 100 for correcting tire nonuniformity is disclosed. The invention is particularly suited for correcting tread runout and connicity problems for large off-road tires. Multiple measurements are taken in multiple circumferentially spaced planes which enable data to be fed into a computer which predicts an optimal profile to correct tire non-uniformities using preset rules. A virtual template directs correction of the tire profile.
    Type: Grant
    Filed: August 4, 2003
    Date of Patent: August 22, 2006
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Daniel Christian Shavers, Douglas Ashley Swift, George Timothy Watts, Robert Dean Irwin, Gary Wayne Corder, Ronald Thomas Dillard, Arthur Warner Moll, Robert Thomas Irwin, Leonard Raymond Holm, Nguyen Bau

  • Patent number: 6508284
    Abstract: The loss of tire contact patch area along the tire's inside shoulder, relative to an oval race course, which occurs during chassis roll and lateral deflection, is reduced by providing an asymmetrical molded tire. The tires are defined by an asymmetrical outer tread profile and the tires are mounted on the rear axle of the race vehicle such that the axially outer portion of the asymmetrical tread region of each tire, relative to the race course, has a greater shoulder drop, wherein the shoulder drop is the difference between the maximum radial diameter of the tread measured on the outer tread contour and the diameter of the tread at the tread edge, than the opposing tire shoulder.
