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.
Annex A gives details of sealing ring grooves and O-rings for earth-mover rims.
NOTE — Terms used are in accordance with ISO 3911:1977, Wheels/rims — Nomenclature, designation, manning and units of measurement.
