Why did so many drivers struggle with the super soft tyres in second practice? Take a closer look at the times from second practice in Canada with the interactive chart below:

Why were the teams struggling so badly with the super-soft tyres? Bridgestone’s director of motorsport tyre development Hirohide Hamashima explains:
The dirty track surface here and the cooler than usual temperatures meant that graining was today?óÔé¼Ôäós talking point. The tyres were not able to work to their full potential due to not reaching their best operating temperature. This meant the tyres were sliding, causing transverse graining on front tyres from braking and transverse graining on the rears from traction demands.
We expect that the track surface will continue to improve with more rubber laid, and the graining will diminish. Weather forecasts also predict warmer temperatures which will be beneficial too. However, there is rain included in these forecasts so there is potential for this to be a very interesting weekend in terms of maximising tyre performance potential.
As Hamashima points out, what the weather does next could be crucial. If it rains before the next session and the rubber built up over three hours of running is washed away the teams could find themselves back at square one.
But, as Fernando Alonso points out, if the weekend remains dry it should become less of a worry:
The soft tyre degrades very easily, but today is only Friday and the track conditions will change a lot between now and Sunday. In Bahrain, after the first day, we were all concerned, but then we all pitted around lap 20 without having any problems.
There is a threat of showers through the weekend and Renault are expecting rain during the race. That would be a different matter, of course, as the teams would have to use their rain tyres.
The unpredictable conditions and lack of grip is giving the teams some serious headaches when it comes to setting up their cars. From radio conversations heard during second practice it’s clear Renault were tweaking their downforce levels and it seems Sauber are doing the same:
The conditions were very difficult to start with this morning. It was a case of running the car in the medium-downforce configuration. Kamui had to learn the circuit today, and for Pedro it was about getting a feeling for the car with the lower downforce level.
Renault, interestingly, had the fastest cars in a straight line in both practice sessions. That position was expected to be taken by McLaren, but even so Jenson Button think the car might be better suited to an even higher downforce configuration they are already using:
We?óÔé¼Ôäóre possibly a little bit too quick along the straights, too. Maybe we?óÔé¼Ôäóre not running enough downforce, but we?óÔé¼Ôäóll look at that.
Red Bull have no shortage of downforce, of course. Sebastian Vettel was fastest in the session despite only having the 19th highest speed through the speed trap – 310.1kph versus Vitaly Petrov’s 319.8kph.
Vettel’s ‘ultimate lap’ – his best three sector times combined – was the second best, one thousandth of a second shy of Alonso’s 1’16.828, with Webber two tenths of a second behind.
While Vettel and Alonso set their best times on the super-soft tyres Nico Rosberg, third fastest, did his quickest lap on the medium compound.
At this stage it looks like being an unpredictable weekend where climatic conditions and difficult decisions about set-up will play a significant role.
All of which makes life even more difficult for the eight drivers who are new to the Circuit Gilles Villeneuve. But at least one of them is relishing the challenge of the Montreal track:
The circuit here is so narrow compared to places like Turkey. It?óÔé¼Ôäós great and much more exciting to race close to the wall as opposed to 200 metres away.
