Sources within Pirelli have confirmed that Nico Rosberg suffered 2 punctures in the laps preceding his second pitstop on lap 51 of the Canadian Grand Prix. The cause of both punctures has been identified as debris damaging the tyre.

The first puncture is understood to have been relatively minor leading to a slow loss of pressure, the second more substantial resulting in a rapid loss of pressure thus requiring immediate serving of car number 6.

Some parties have questioned Mercedes decision to service Nico with a set of Soft tyres in his second (unplanned) stop on lap 51. With only 19 laps to go both the Super Soft and the Ultra Soft compound could have completed the race distance. However as this article indicates, going into the race Nico had no fresh Ultra Soft tyres available, it is unlikely a used set of Ultra Soft compound tyres would have completed the race distance. The decision not to run the red Super Soft tyres will have been down to the issues Nico was managing in the car around fuel consumption and brakes. A tyre with greater performance could have led to greater issues in the closing stages of the race.

Commenting on Nico’s struggles Paddy Lowe remarked:

“For Nico, a late puncture[s] forced a second stop. It looks like he also collected some debris in one of his radiators, as he had overheating throughout the race. While this may not necessarily have affected his performance, it would have been quite a big distraction to manage. A podium was a possibility for him today – but unfortunately it didn’t work out”

Adding to this Nico himself commented on his race:

“I did my best to fight back and I there was a chance of a podium – but then I got the puncture and had to pit again – dammit! I was pushing hard after that to regain the positions but it was a massive mission managing the car with brake warnings coming on and running low on fuel.”

Pirelli went on to confirm that of the drivers that did manage to successfully complete the race on a single stop strategy; Hamilton, Bottas and Alonso. Did so well within the life of the soft compound tyre. Whilst confirmation of the number of laps it could be expected the tyres would have completed beyond race distance remains confidential Pirelli confirm no driver was near the limit of the life of the tyre.
