衛視講賽車條陳乜能沈乜成真係廢柴!

draghixa C Hing, I think the 衛視 commentators were correct.  Under normal dry conditions, an F1 car must have all 4 tyres with the same type of compound. However, in Shanghai, it was declared a wet race at the beginning of the race, therefore the cars can have any combination of tyres they would like on their cars for the entire race, even with 1 wet, 1 intermediate, 1 soft dry and 1 hard dry if they want.  So the Ferraris put a harder compounder tyre on the left front during the second half of the race.
