Super single tire
The term supersingle stands for a commercial vehicle tire with extra width.
The purpose of this type of tire is to carry the axle load instead of twin tires . The advantages of super single tires result from the smaller overall width compared to twin tires.
However, since the advantage of the smaller overall width can only be converted into an increased loading volume with a frame “tailored” to the new type of tire, the biggest selling point has so far not come into play. Due to the low level of acceptance on the market, there are almost no frames that are tailored to the super single; the space advantage therefore remains unused so far.
Another advantage of the super single is its lower rolling resistance coefficient . This is in the range of f = 0.0045, whereas values around 0.006 are usually assumed for twin tires.
A disadvantage of the super single tire is the lack of redundancy. If a tire fails with twin tires, the axle load can be borne by the still intact tire, at least for a short time. If, on the other hand, the super single tire fails, it is no longer possible to continue driving.
This design-related disadvantage is counteracted by equipping the tire with emergency running systems. These are available from different manufacturers, although the functionality differs but is similar.
