  • Method and apparatus for balancing tires during retreading
    Patent number: 7468111
    Abstract: A method and apparatus for balancing a tire during a retreading operation includes measuring the radial runout the buffed tire casing and applying the gum layer and tread strip to compensate for variances in runout. The gum layer is applied so that an overlap or smear is formed at the relative low portion of the casing. The tread strip is applied with the joint at the same low portion in cases where the low portion has a relatively large variance, or at another location if the variance is small or other low portions exist. In addition, the thickness of the gum layer and tread strip may be controlled for further compensation of the runout variance.
