  • Internal tire balancing of rubber tires on rims
    Patent number: 10919245
    Abstract: A process for balancing a rim and tire, which comprises first balancing the rim, then mounting the tire, properly inflating it and balancing a second time to determine the location and weight of balancing required. The tire and rim are then indexed with marks to indicate where the balancing weights should be placed. These indexing marks will be used at the remounting stage to assure proper balancing. The tire is then deflated and removed from the rim and the correct mass rubberized weights are vulcanized to the internal surface of the tire sidewall at the indexing mark and on the opposite sidewall across from the indexing mark. The tire is then installed back on the rim with the indexing marks lined up next to each other. The tire is re-inflated and the balance re-checked with a spin balancing machine.
