This disclosure relates to an adjustable width wheel rim, or more particularly, an assemblable, adjustable-width rim for mounting tires on motor vehicles. The adjustable width wheel rim may include a central tubular drum with two lateral sections delimited by a central section with two annular stop edges. Each lateral section is configured to axially receive a double-walled “C”-shaped insert up to a stop. Each insert includes a thread on the outer wall and a thread on the inner wall, allowing it to be screwed onto double-walled “C”-shaped tire mounting rings with a closed-end, defining an outer wall with an internal thread and an inner wall with an internal thread. These tire mounting rings and inserts include axial through-holes at their closed ends, designed to axially receive bolts that penetrate through axial holes in the annular edge of the central tubular drum to secure the entire assembly.
