Main manufacturers and examples of models:
Michelin: (enduro, cross, trial, rally raid)
Dunlop: (cross, rally raid, trial)
Pirelli: (cross, enduro, trial)
As a general rule for cross, enduro and trial, the softer the rubber, the better the grip on wet terrain. It is better to choose a hard rubber tyre for dry and stony terrain.
As far as the rally raid is concerned, for now there is no difference in the hardness of rubbers. However, you have a choice between different models of tyre - usually you either choose a model which is more adapted to a mixed earth / stony terrain (Baja by Michelin) or a model for sand (Desert by Michelin).
Most manufacturers of all terrain tyres make this distinction on their tyres. Be careful during mounting. Some bikers turn the tyre in order to gain extra grip. Although this is possible it is not, of course, recommended by the manufacturer.
Tubeless tyres require a particular bead wire clamp due to the fact that the bead wires have to form a very tight joint on the rim. Not all moulds are suitable for manufacturing a tubeless tyre. Do not mount tyres without inner tubes, unless the manufacturer recommends this. If a chamber is mounted, it is possible to mount a tubeless tyre on a rim with an inner tube.
TL :the abbreviation for TubeLess. When mounted on a tubeless rim, tyres bearing this indication do not need an inner tube.
TT :the abbreviation for TubeType. The tyre has a separate inner tube.
The Bib-Mousse is intended for use in all terrain competitions with tyres and must not be used on public roads. It is inadvisable to mount it on tyres made by other brands.
