Standard Tires without Emergency Running Characteristics
-
- I - Standard tires with air
-
- II - Standard tires without air
-
If the standard tire loses air, the rim presses the side wall together. The rubber in a flat tire is heated strongly and quickly looses its properties.
SST Tires with Reinforced Side Wall
-
- I - SST tires with air
-
- II - SST tires without air
-
Especially thick side walls support the empty tires on a standard rim and the vehicle remains maneuverable. A special rubber mixture reinforces
the tires and supports the vehicle in an emergency.
The self-supporting, reinforced side walls form the basis of SST technology.
