702157, 157 13

Abstract:

A method and apparatus 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.
