my mistake, I missed the last sentence here:search wrote:I didn't know that the red tire (additionally to the yellow one) is mandatory for the race... so if Red Bull can more or less follow the Mercedes and manage to do a one stop, they could really end up with a chance to win
What the heck did Williams do there yesterday then, cruising around with the red (race) tires in Q1?!
These are the tyres that Pirelli has said must be used at some point in the race:
One set of P Zero Yellow soft
One set of P Zero Red supersoft
Each driver must have both these sets available for the race, and must use at least one of them.

so only one of those sets is mandatory
