The official TIREBOT catalogue organises tyre models into three main groups: PCR, TBR and OTR. This is a useful first filter, but a group name alone cannot establish whether a model is suitable for a particular vehicle, machine or operating environment.
Why start with the product group?
The product group directs the reader to models created for the right class of equipment. A passenger car, a heavy commercial vehicle and an earthmover place very different demands on a tyre, so they require different technical inputs from the outset.
Once the group is clear, check the model’s documented application, available sizes and other published technical fields against the original product record.

OTR
The official catalogue group associated with mining, earthmoving and other heavy-equipment applications.

Models within the same group can carry different application labels, sizes, constructions and service descriptions. A model appearing in a global catalogue also does not establish current availability in a local market.
A sound review combines the vehicle or machine manufacturer requirements, the verified technical record for the exact tyre model and the real operating conditions.
Before opening a model page
- Identify the vehicle or machine and locate its manufacturer documentation.
- Record the current tyre size and required service markings accurately.
- Prepare operating information such as route, ground, axle position or machine duty.
- Compare the model-page data with the original source and manufacturer requirements.
- Confirm current local availability through the relevant sales channel.
In summary
PCR, TBR and OTR make it easier to reach the relevant part of the catalogue. The final assessment still depends on the exact model data, manufacturer requirements and operating conditions.
