Here are some run times (1 minute +) from the last day of the Barcelona test:

"Webber did 59 quick laps during his three-stop race simulation. We think tyre use went soft-soft-hard-soft. Red Bull has been the best at holding onto the tyres, but the times drop away pretty quickly when he is on a full tank throughout both the first two stints.

The hard tyre hangs on a lot better and for a lot longer, but the pace is not as impressive as we've seen it. Webber explained after the session that the steep drop-off at the beginning of the final stint was due to traffic and not the tyres. The feeling is that this was quite a conservative run, and Webber admitted that they would do things differently in later race sims..."

Webber
29.7, 29.8, 30.1, 31.4, 32.0, 32.0, 32.4, 33.2, P
27.4, 27.9, 28.9, 29.8, 30.2, 30.8, 31.1, 31.3, 31.9, 32.4, 32.6, 33.2, 33.6, P
29.9, 29.6, 29.8, 30.3, 30.8, 30.2, 30.8, 30.4, 30.6, 30.7, 30.6, 32.6, 31.8, 31.3, 31.1, 32.3, 32.5, 32.3, 33.6, 33.2, P
24.9, 28.3, 29.1, 28.4, 28.3, 28.3, 29.0, 28.5, 29.0, 29.4, 28.6, 29.1, 32.0, 29.2, 30.1, 29.8, 30.3, 30.7

"McLaren only did one run of more than 10 quick laps, and it was this 16-lap effort. The times are scattered all over the place and the only explanation Hamilton would give afterwards was that he was getting overtaken a lot... So we're still waiting for a positive sign on the MP4-26."

Hamilton
29.5, 29.1, 29.4, 29.7, 32.1, 30.8, 34.8, 30.8, 37.0, 31.1, 31.4, 32.3, 44.5, 51.9, 49.2, 34.3

"Ferrari did a lot of laps again. There was no race simulation, but there were a couple of runs of around 30 laps. This one was 27 with one stop in the middle, and the F150 Italia held onto the tyres impressively - less than two seconds slower after 14 laps. The pace was a lot more varied after the pitstop, but the genuine pace seems to drop by around two seconds again."

Massa
28.2, 36.5, 27.8, 28.1, 28.3, 28.7, 29.0, 28.9, 28.9, 29.3, 29.2, 29.4, 29.9, 30.1, P
31.5, 26.5, 26.9, 31.4, 27.3, 27.4, 27.6, 28.3, 28.4, 28.9, 32.1, 28.0, 28.1

It's clear from this that some are happier than others with the Pirelli tyres.
