83.160.30 - Tyres for agricultural machinery

This document sets out the marking, the tyre size designation, the dimensions, the load ratings and the rim coordination for logging and forestry service tyres in diagonal and radial construction. Rim dimensions are given in ISO 18804.

This document establishes the load ratings of the diagonal code designated (ply rating marked series) tyres for agricultural tractors, trailers and machines. Tyre designation and dimensions, and approved rim contours are given in ISO 4251‑1. NOTE Code designated diagonal tyres (ply rating marked series) for construction applications (industrial tractors), identified by the classification code R-4, as specified in ISO 18805, or by suffix "IND" are part of ISO 13442.

This document establishes the tyre size designation, the dimensional calculation formulae, the markings and the tyre and rim coordination for the metric series of tyres primarily intended for use on agricultural and forestry tractors, machines, equipment and trailers and for construction machines. It applies to diagonal, bias-belted and radial tyres mounted on 5° and 15° tapered rims. NOTE Code designated series of: — diagonal (ply rating marked) tyres for agricultural tractors and machines are ...view more

This document establishes the service description, the tyre load ratings for basic and special applications and reference inflation pressure for the metric series of tyres primarily intended for agricultural tractors, machines, equipment and their trailers. It applies to diagonal, bias belted and radial tyres mounted on 5° and 15° tapered rims. NOTE The service description, the tyre load ratings for basic and special applications and reference inflation pressure for the metric series of: — tyres...view more

This document specifies the marking, dimensions, load ratings and reference speeds for code-designated agricultural tractor drive-wheel tyres with service description (load index and speed symbol). It applies to tyres of radial construction in the speed categories 40 km/h (speed symbol A8), and 50 km/h (speed symbol B). NOTE Code designated series of: — diagonal (ply rating marked) tyres for agricultural tractors and machines are specified in ISO 4251‑1 and ISO 4251‑2; — tyres for logging and fo...view more

This document specifies the method for measuring rolling circumference for new tyres, under loaded conditions, made for use on agricultural tractors and machines, and applies to agricultural tractor drive wheel tyres in diagonal and radial construction. It also includes an explanation of the rolling circumference index (RCI) and speed radius index (SRI).

ISO 18804 specifies rim dimensions for rims for agricultural, forestry, and construction machines. All dimensions in ISO 18804 are given in millimetres and are applicable to the side of rim which is in contact with the tyre during the mounting and in service. NOTE Terms used are in accordance with ISO 3911.

ISO 18805:2017 specifies the classification codes for agricultural and forestry tractors and machines.
