Abstract:
A method for correcting the conicity value of a tire having a circumferential tire tread with top and bottom shoulder regions and a central region therebetween, said method comprising the steps of:a) calculating a conicity value (CV) of said tire; b) comparing the absolute value (NCV) of said CV to a target conicity value (TCV) and continuing with step c) if said NCV is greater than said TCV and equal to or less than a maximum conicity value (MCV), c) pre-positioning (PREP) a grinder assembly with respect to said tire; d) grinding rubber from said selected one of said top and bottom shoulder regions, measuring lateral force while grinding, and using lateral force measurements as feedback for controlling the grinding time; and e) returning to step a).
