Paul Hembery: “The teams were presented with a very short amount of time to evaluate the soft and supersoft tyres before qualifying, but from what we have seen so far we would expect most of the drivers to make three stops tomorrow. This is in line with the average number of pit stops we anticipate over the year as a whole, but we also wanted to test the boundaries of our compounds in the final part of the season as we make some decisions for 2012.
“The supersoft tyre looks set to work effectively for about 10 laps tomorrow while the soft tyre is good for up to 20 laps. We’d expect the time difference over a lap between the two compounds here to be in the region of 0.7s to 1.0s, based on what we have seen today.”
