Both Renault and Haas drivers will take on the Canadian Grand Prix without any super-soft Pirelli tyres to maximise its allocation of softs and the new ultra-softs.

In a move not seen so far with the new tyre regulations, Renault and Haas will have zero sets of the red-banded super-soft tyres which comes after the new ultra-softs competitive debut at the Monaco Grand Prix.

The tyre selections are made seven weeks in advance of long haul races to give Pirelli time to prepare the number of allocations required. But the bold move doesn't look to be a gamble after Lewis Hamilton called the new ultra-soft 'the super-softs painted purple' in Monaco.
