you've also got to remember how these tyres are made.. instead of being rubber filled with air they are a carbon fibre material, with rubber around that filled with nitrogen.. chemicals are then bonded with the rubber to and it is the reaction of that chemical with the track that generates heat and grip.. that heat then has to dissipate throught the sidewall of the tyre..

Michelin brought 2 tyres to the track with different chemicals to provide different levels of grip and durability but they were still manufactured in the same way.. the problem was that the build up of heat was greater than they expected because of the new surface and the heat wasn't dissipating through the sidewall.. this led to the tyre failures and was the same with both sets of tyres they brought

Michelin had never run an Indy since last year and obviously they had very litle data on the new surface unlike Bridgestone.. you can't expect them to just make a new tyre in 24 hours in a completely new way they would be even more dangerous
