US qualifying quotes: Pirelli

Paul Hembery: "Our tyre choice here is on the conservative side, which means that getting the tyres up to the right temperature was important. That was not necessarily an easy task today as the track temperature actually fell slightly during the session, which is not the normal pattern we see in qualifying.

"With variable winds and temperatures throughout the afternoon, it wasn't a particularly easy session for anybody. The track has still been evolving today, but tyre wear and degradation should not be a considerable factor for the race with either compound. As a result, we will probably see just one pit stop for most runners, as was the case last year."
