I guarantee the masters of marginal gains, Sky (now Ineos Grenadiers), will have spent some resources on looking at which tyres are actually faster for them, regardless of fashion or sponsors.
I think it’s safe to say that whatever they ride on are the fastest options - and every other team would follow - or that within a certain set of parameters, it doesn’t matter.
I just tried to search to see if Ineos run different tyres on different race and stages, and found nothing conclusive.
According to eurosport commentary they do change wheels and tires based on the race. That said they use rim brakes so probably never go over 28m tires.
