<p>PROBLEM TO BE SOLVED: To provide an inner multi-piece rim capable of making labor and time for tire change less than ever.SOLUTION: An inner multi-piece rim 20 includes an outer bead seat band 23, an outer side ring 25, an inner bead seat band 26, and an inner side ring 28. Thus, when a tire T20 is detached from a rim base 21 of the inner multi-piece rim 20, the tire T20 can be detached by an assembly of the outer bead seat band 23, the outer side ring 25, the inner bead seat band 26 and the inner side ring 28. Thereby, an assembly structure of the tire T20 detached from the rim base 21 of the inner multi-piece rim 20 can be set identical with an assembly structure of a tire T10 detached from a rim base 11 of an outer multi-piece rim 10. Consequently, labor and time for tire change can be set less than ever.</p> |
