Casey Stoner get his pole position on Catalunya, but he's a little bit worry about the tyre. During the practice session, Stoner (and Pedrosa) were trying both hard and soft tyre and also did long simulation. Stoner said that the tyre will be a role for tomorrow race.
"We used the qualifying as an extended practice session as we don't always have enough time to do everything during the 45 minute sessions. This morning we did a lot of work with the hard tyre, so in the afternoon in these hot conditions, we worked more with the softer one to get a clearer understanding if we can run with it for race distance."
"We were in and out a lot during the session trying a few different things, hoping to reduce the chatter which is still proving to be a problem, as soon as I touch the throttle the bike starts to chatter in the rear and it's making things very difficult.
"Towards the end of the session we managed to improve it slightly but I think we need to make another step before the race. Tomorrow, for sure tyre degradation is going to play a role so we're going to have to wait and see but I'm happy to start from pole."
