Subsection of BS AU 50- the following definitions apply 3.1 basic pressure the inflation pressure related to the load that would, under optimum conditions, produce the most economical tyre life 3.2 dual spacing the distance between the centre line of tyres in dual fitment 3.3 permitted rim any rim, in addition to the recommended rim, whose fitment is permitted 3.4 recommended rim the rim(s) that gives the best fitment of the tyre for all conditions and types of service Industrial vehicle pneumatic tyres 4.1 Tyre markings 4.1 All tyre markings shall be permanently and legibly marked on both sidewalls in accordance with BS AU 50- 0c: 977 4.1 Each tyre shall be marked with its size using one of the following designations a) Nominal section width code Construction code b) Nominal overall diameter code × Section width code; c) Nominal overall diameter code × Section width code Nominal rim diameter code; Construction code Nominal rim diameter code Additionally the tyre may be marked with its service condition characteristics Where these markings are included they shall be set out in the following order: load index NOTE speed symbol ply rating Examples of the use of these designations are given in Annex A 4.1 For diagonal tyres the construction code shall be “—” For radial tyres the construction code shall be “R”, and/or the word “RADIAL” marked elsewhere on the tyre 4.1 For industrial and fork lift tyres the speed symbols shall be A5 corresponding to a reference speed of 25 km/h For commercial vehicle tyres used in industrial applications the speed symbol shall

specified in Table 3, Table 5, Table 7, Table and Table shall be the basic pressure relating to the specified reference loads or load capacities NOTE The pressures used in practice on the vehicles may be fixed by agreement between the tyre manufacturer, the vehicle manufacturer and/or the user They should take into account, in addition to the load, the operating conditions, the stability requirements and the mechanical characteristics of the vehicles 4.3 Normal section tyres Normal section tyres shall be in accordance with Table and Table 4.4 Wide section tyres Wide section tyres

both sidewalls in accordance with BS AU 50- 0c: 977 Band tyres Each tyre shall be marked with its tyre size using the following designation: Overall diameter × Tyre width × Internal diameter of tyre band The tyre designation shall correspond to the design dimensions of the tyre and shall be marked in inches NOTE It may additionally be marked in millimetres An example is given in Annex A While the tables for the millimetric design dimensions may show wheel (rim) diameter to one decimal place, the tyre size designation marking shall be rounded off to the nearest millimetre Resilient tyres (i.e solid tyres for use on pneumatic rims) Each tyre shall be marked with its tyre size using one of the following designations Nominal section width code – Nominal rim diameter code/Nominal rim width
