Free practice today went as expected, with the soft tyre also proving to be very close in performance to the supersoft, making the soft a viable alternative from what we can see so far. Both of these compounds are just under a second faster than the ultrasoft as far as we can tell at the moment, although there has been an even higher degree of track evolution than usual during FP1 in Montreal due to a particularly dirty track. This is a circuit that is normally known for graining, but we’ve not seen any of that with the latest 2017 tyres – as has also been the case at all the other circuits this season.
