It is interesting that McLaren said in their launch interviews that they are taking special care to keep the tyres in better condition – it wasn’t entirely clear if they did that in creating the suspension, or intend to work with their new car to get that, but it does show how much of a concern the tyres are to the teams this year.
I do think that it might add some interesting differences: some teams being quicker, but then unable to make the tyres last in the race, while others might be a bit slower, but can make the tyres really last.
I think on the last day of the test quite a few people were able to drive long stints with good consistency, so even if the initial loss of grip is rather steep, the tyres do seem to bottom out at a consistent level after that.
