Peter Bayer said that one of Lawson's tires (must be the hard) had a cut, so they weren't allowed to use it anymore in the end. Let's hope it was just a coincidence...
About strategy, he said that the Soft is a pure qualifying tire which wouldn't hang on for more than six or seven laps. It'll be (2x) medium & hard for the race.
edit: about the forced two-stopper he said, that according to their calculations, it's 20s slower than a one-stopper they would otherwise do.
