Quote from Mustangman759 :

R1s are softer compound than R2 and therefore heat less. Pitting isnt needed and no one would take any tires or fuel if we required it. they would just stop and go.
Edit: unbanned you but please read rules.

I know that R1 is the softest one, but:

EDIT: sorry i meant the pitstop rule is mandatory full 4 tyre change stop, like last season. But i understand if its impossible, reason admin maybe cant follow the stops during the race...
