ISO 3739-1:2007 specifies the main requirements of the metric series of pneumatic tyres primarily intended for industrial vehicles, including designations, dimensions and markings. The tyres are based on the following parameters:
- speeds not exceeding 50 km/h;
- use on 5° tapered or flat base rims.
The conversion of code-designated industrial tyres into metric-designated tyres is outside the scope of ISO 3739-1:2007.
