There are many possible causes for a tyre to fail and could include:
1. Not inflating to the manufactures recommended pressure. This is the most prevalent reason for failure as it causes de-vulcanisation.
De-vulcanisation is the chemo-mechanical process which causes the tyre compound to break down, mainly through heat build-up due to under-inflation. Heat build up is by far the major contributor to any failure of this nature .
Most bike tyres of this ilk are also biased ply in their construction which causes them to also run a lot hotter than a steel belt tyre.
It is for this reason that manufactures recommend a specific tyre pressure for a given load and it is vitally important to adhere to this
2. A structural defect at manufacture .
3. Damage due to road conditions eg. A cut or tear from a sharp object.
We do note that this tyre was run under load , at high temperatures below the manufacturers recommended tyre pressure of 3.0 Bar
It would make no sense for us to speculate as to the cause in this instance or to jump to any conclusions even if run under the recommended pressure.
The best would be for this tyre to be evaluated by the manufacturers in their lab and we will forward it to Germany for this.
