Pirelli have stated that they estimate 35 laps on the US.godlameroso wrote: ↑28 Oct 2017, 17:00But the race is 71 laps, he'd have to run to lap 35 at least to make a one stop work. Unless he's planning a US and run S until the end.
On full tanks the lap time is at best high 1:20's but likely mid 21's, however the degradation and fuel effect means lap times will remain constant. The SS is useless as a race tire, the long run pace is inconsistent, the softs are marginally slower in the race but far more consistent.
I would do US to lap 31 and finish the race on Softs, the US SS strategy won't work as a one stop.
US to lap 24, US again to lap 48, and the final stint in SS would allow one to push hard the whole race without worrying about tire wear. The one stop is potentially faster but takes more management, any mistakes or inconsistency in pace will make it not work. If there is a safety car a two stop will be the faster strategy as it will mitigate the pit time loss, moreso if it's a virtual safety car.
