4.2 Tyre Size, Ply Rating and Load Index Tables

1. Locate the line entry corresponding to the size and ply rating or load index marked on the tyre sidewall;

2. Read off the maximum axle load (kg) for these tyres in ‘SINGLE’ or ‘TWIN’ formation, as appropriate.

3. These tables show the maximum axle load for tyres in single and dual (twin) formation.  If a tyre has only one load index marked, then that index refers to use in single formation. Such tyres can be used in dual formation by applying the following formula:

Max. load in dual formation = Max. load shown for single x 1.91
