 In both cases the tyre will be heated and expands to slightly greater than the wheel's diameter, and is fitted around it.After cooling, the tyre contracts, binding tightly in place.A common method used in industry is the use of induction shrink fitting which refers to the use of induction heating technology to pre-heat metal components between 150˚C and 300˚C thereby causing them to expand and allow for the insertion or removal of another component.
