Шины и ободья велосипедов. Часть 1. Обозначения и размеры шин
Название (англ.):
Bicycle tyres and rims; part 1: tyre designation and dimensions
Описание (англ.):
This third edition cancels and replaces the second edition (1980) and its addendum 1 of 1982. It specifies the main requirements for 'wired edge' tyres mounted on straight side or crotchet type rims, and for 'beaded edge' tyres mounted on hooked bead rims. An annex which does not form a part of the standard gives the old markings (table 5) for tyre sizes from 28 - 590 up to and including 67 - 381.
