Super-soft tyres lasting far longer than expected | 2011 Monaco GP FP2 analysis

Adrian Sutil, Force India, Monaco, 2011

Pirelli expected their super-soft tyre would be good for no more than ten laps in Monaco^[1].

But in second practice the tyres were lasting for more than 20.

Here?s all the data from the second practice session.

Longest stint comparison

• In second practice the super-soft tyre held up surprisingly well over long stints. Sebastian Vettel^[2] did a 23-lap stint on them and was able to lap in the high 1?18s (see graph below)
• Jenson Button^[3] did similarly well on his run on super-softs (also below), improving his best time by half a second 16 laps into his stint
• Will the tyres last this well in the race? It?s not a given as Monaco typically sees very high track evolution as the surface becomes cleaner and grippier. But at this stage Pirelli?s initial estimate of ten-lap stints on the super-softs looks very conservative

Complete practice times

• Narain Karthikeyan^[4] was outside the 107% time from Q1 (1?21.982) set on soft tyres. If his FP2 time was set on super-softs, it does not bode well for his chances of qualifying
• Giedo van de Garde, Sam Bird and Jules Bianchi were all faster than Karthikeyan in the GP2 qualifying session held after second practice
• Another unexpected property of the super-soft tyre was that some drivers were able to improve their times after their first lap. This could have an effect on qualifying, allowing drivers an extra chance to set a good lap if they get stuck in traffic

Ultimate lap times

• Taking all their sector times into account the gap between Fernando Alonso^[5] and Lewis Hamilton is even smaller. But remember Hamilton set his best time later in the session, benefiting from the track evolution
