ISO 7867-1:2005 establishes the size designation, the dimensional calculation and the markings of the metric series of tyres primarily intended for use on agricultural tractors and machines. Tyre and rim coordination is also given.
ISO 7867-1:2005 applies to bias-belted, diagonal and radial tyres mounted an 5° tapered rims, as specified in ISO 4251-3. Only established rim diameters and widths within the ranges in Tables 1 and 2 are recommended.
ISO 7867-1:2005 also applies to different concepts and types of tyres and rims; in this case, however, appropriate rim/section ratios K1 and coefficients K2, a and b will be established and added.
Dimensions of existing rims are specified in ISO 4251-3.
