We have to work very hard to get the tyres into their operating window; definitely harder than other teams.
The operating window is tight so there's a very small margin between a good time and a bad time.
The tyres are very important (for overall performance)
and we're struggling to get them up to temperature. The tyres are very different from last year where they were easy to heat up but had to be managed to avoid over-heating during the race. This year, it's the exact opposite and, if you can't keep the tyres up to temperature, you lose grip. This is where we are suffering.
Regarding errors in the car design philosophy
: This year we've got a car that's good on the straights but we're definitely behind on downforce and this is what helps heat the tyres up.
With regards to Pirelli
: they've delivered the exact tyre they were aiming for. It's normal that some teams will produce a car that benefits more automatically to these characteristics than others.
All our work is focussed on finding the more grip which will enable our suspension to work better too. The focus is the tyres, not the suspension.
The last line is the most telling. Sounds like they're running the suspension outside the ideal setup to compensate for the tyres.
