But while a tyre may look visibly okay on the outside, Bridgestone had arrived at their decision after cutting open the Friday tyres for examination.
Ducati's Andrea Dovizioso confirmed: "The hardest tyre was the worst to see on the outside, but every tyre they cut they saw the blisters yesterday. When we made a good lap time at the end of the practice Bridgetone said that the inside was not OK and they said that more than 14 laps was not good."
