ISO 7867-2:2005

ISO 7867-2:2005 establishes the service description, the tyre load ratings in basic and special applications, and reference inflation pressure increments for the metric series of tyres primarily intended for agricultural tractors and machines.
It applies to bias-belted, diagonal and radial tyres mounted on 5° tapered rims, as specified in ISO 4251-3. It also applies to different concepts and types of tyres and rims; in these cases, however, appropriate load/speed curves and reference inflation pressure increments will be established and added.
Basic tyre load-carrying capacities for ranges of existing tyres are also given.
