Season
The season (and, accordingly, the temperature regime) for which the tyre is designed.
"Seasonality" is primarily due to the fact that any composition used in the construction of motorcycle tyres has a certain temperature range in which it shows optimal performance. If the temperature is too low, the rubber will remain hard and will not provide the desired degree of grip, and if it is too high, it will soften, impair stability and be subject to increased wear. In addition, winter and all-season models often have specific design features that ensure efficient operation in difficult conditions — special-shaped grooves for effective moisture removal, massive protrusions for “biting” into the snow, etc. Therefore, it is highly undesirable to deviate from seasonal recommendations.
At the same time, it is worth noting that motorcycles themselves as a mode of transport are designed mainly for use in the warm season — by the word "season" most owners of motorcycles mean the period from approximately mid-spring to mid-autumn. Therefore, the vast majority of motorcycle tyres are
summer tyres,
all-season models are very rare, and winter tyres are even rarer, mainly among
cross -country rubber (see above).
Tyre type
—
Chamber (TT). Tyres, consisting of a tyre and an internal sealed chamber into which air is pumped. Despite the "double walls", such tyres are inferior in reliability to tubeless ones — they quickly release air when punctured, and in general they have more modest performance characteristics. At the same time, chamber tyres also have advantages: they are insensitive to rim deformations and retain their tightness even when there is a gap between the rim and the tyre. Thus, there are two main areas of application for such tyres today. Firstly, these are spoked wheels, where the rim does not provide tightness and you cannot do without a chamber; such wheels are installed on many east european motorcycles, as well as some choppers. Secondly, tube tyres are used by some extreme riders or long "
enduro " style travel enthusiasts (see "Directionally").
—
Tubeless (TL). Tyres that do not use an inner tube — the air in such models is pumped into the space between the tyre and the wheel rim. This design requires a one-piece rim that does not allow air to pass through, and only works properly on cast wheels, without spokes. On the other hand, the vast majority of modern motorcycles are equipped with such wheels. Tubeless tyres are considered more reliable and safer than tube tyres, they tolerate punctures better (in particular, they hold air longer), and they are easier to rep
...air. Therefore, in general, such tyres are preferable to tube tyres (with the exception of some specific cases described above).
— TT/TL. Tyres that can be installed in both tube and tubeless ways — depending on which option is required in this case, taking into account the type of wheel and application.Reinforced / RF
Reinforced tyres with extra ply cords to provide increased load capacity and withstand high loads. Such tyres are marked with the designations Reinforced, REINF or RF.
