Mercedes and Ferrari both only have one set of new hard tyres for each of their drivers, leaving them short for the ‘best’ strategy for the Canadian Grand Prix.
Pirelli announced the medium-hard-hard two-stop will be the best strategy to go with for Sunday’s race.
Saturday’s wet sessions mean that all 10 teams have plenty of mediums and softs to spare, but Mercedes and Ferrari will be praying that the medium tyre runs longer than expected.
The hard tyres’ longevity makes the medium-hard-hard strategy the best option, but medium-hard-medium, medium-hard, and hard-medium strategies may all be viable options for a number of drivers, especially if a safety car or red flag is called.
Why no soft tyre?
The soft tyre is not included in any of the above strategies because it simply does not hold any reward for the short-running pace advantage it gives drivers before falling off the ‘cliff’.
That is, unless a safety car or red flag is announced with around ten laps to go.
All 20 drivers have at least two sets of new soft tyres to choose from if needs must.
