ISO 4250 consists of three parts (see the Foreword) laying down the technical elements relating to
designation and dimensions of tyres and rims for earth-moving machinery: it also gives load tables for these
tyres.
This part of ISO 4250 sets out the designation, contours and dimensions for rims for narrow and wide base
off-road tyres primarily intended for earth-moving machinery.
All dimensions in this part of ISO 4250 are given in millimetres and are applicable to the side of the rim which
is in contact with the tyre.
Tyre designations and dimensions, tyre classifications and nomenclature are given in ISO 4250-1, ISO 10571
and ISO 13442.
Annex A gives details of sealing ring grooves and O-rings for earth-mover rims.
