Mitas e 07 are great tyres I used two sets on my previous GS and GSA. One day I noticed a few smal cracks on the tyre, I did not bother about it until it started leaking air, then I contacted the supplier, the lady was very friendly and told me to go to the dealer and swop the tyre. Before going to the dealer, I went to a colleague, which is an expert on failure analysis, he told me the perceived cracks were caused by a sharp foreign object, I immediately called the supplier and told them there are nothing wrong with the tyre, it was my fault and I replaced the tyre at my own cost.
The point is, how many people claim tyre failure, while it was not actually failure of the tyre.
