Temperature increase caused by insufficient inflation pressure > < Tyre damage due to insufficient inflation pressure
Slow loss of tyre pressure
Slow loss of tyre pressure
Slow loss of tyre pressure is particularly problematic, because even experienced drivers are often not aware of it happening.
Insufficient tyre pressure and the subsequently increased amount of flexing (internal friction) causes the tyre material to heat up considerably and may lead to the separation of the various components and rubber compounds.
In the end, the tyre is usually destroyed completely.
The cause for the slow pressure loss cannot always be determined because the tyre is severely damaged and structural components of the tyre are missing.
The following illustrations show tyres which were destroyed by driving with insufficient inflation pressure.
