An off-highway wheel rim has a flange formed with a frustroconical outwardly directed band at its radially inner surface. The band abuts an inwardly directed surface on an upturned edge of the rim so that in the free body state the opposed surfaces diverge. Upon inflation of the tire, the faces are brought into engagement by the pressure forces within the tire to produce face-to-face contact between flange and rim.
