ISO 18808 specifies the designation, dimensions, approved rim contours, load ratings and reference speeds for agricultural tyres fitted to construction machines (e.g. backhoe loaders, small dumpers, loaders, excavators) operating on building sites under loading and transport conditions.
Tyres conforming to this ISO 18808 are identified by the suffix IND in the tyre size designation; code designated tyres can alternatively, in place of the suffix IND, be identified by the classification code R-4.
NOTE: Agricultural tyres without the suffix IND in the tyre size designation or with a classification code differing from “R-4” are not part of ISO 18808 . Code designated diagonal tyres (ply rating marked series) for agricultural tractors, trailers and machines are part of ISO 4251-1 and ISO 4251-2. Code designated radial tyres for agricultural tractors, trailers and machines are part of ISO 8664. Metric designated tyres for agricultural tractors, trailers and machines are part of ISO 7867-2. Tyres for forestry machines, identified by suffix LS, or classification code LS-x are part of ISO 18807.
ISO 18808 on agricultural tyres for construction machines is useful for:
Agricultural tyres are fitted to various machines performing essential functions on the field. Thus ensuring their adherence to the the established standards is necessary.
Compliance with ISO 18808 helps you ensure your machines are efficiently performing functions like cyclic haulage service, loading and carrying, driving away.
ISO 18808 gives you information about the designation, dimensions, approved rim contours, load ratings and reference speeds for agricultural tyres fitted to construction machines and all the additional guidance that is needed so that you can manufacture agricultural tyres fitted to construction machines in compliance with European standards.
