Off Highway Tyres

Tyres fitted on to Trucks & Equipment used for Construction, Farming, Material Handling, Mining etc. fall within this category. OFF-THE-ROAD TIRES are classified by the Tyre and Rim Association (TRA). A TRA code always consists of a letter that is followed by a number, although this number is sometimes also followed by another letter. The first letter indicates for which type of machine the tyre can be used. The next digit indicates the tire’s tread depth.

There are four types of OTR and industrial tyres – based on their application. The designated category can be found on the sidewall of the tyre. The types are listed below; and are reflected in the first letter(s) of the TRA code:

• C    Compactor
