Abstract

1,220,362. Grinding tyres. GENERAL TIRE & RUBBER CO. 16 Jan., 1968 [1 Feb., 1967], No. 22872/70. Divided out of 1,220,361. Head- .ing B3D. [Also in Divisions B4-B5] The subject-matter of this Specification is substantially the same as described in Specification 1,220,361 but the claims are concerned with a method of reducing the magnitude of a force variation generated by an inflated pneumatic tyre rotating against a surface under an applied load. The method includes the steps of determining the location and amount of the force variations, removing an amount of rubber from the tyre and controlling the amount and location of the rubber removed to correlate with the characteristics of the corresponding force variation so as to diminish or annul it.
