"At the Belgian Grand Prix this weekend the three tire options will be non-consecutive. Pirelli confirmed on Monday that the C1 — the hardest tire in Pirelli’s range — will be the hard tire, but then the C3 will be the medium, and the C4 will serve as the soft."
"This is the first time since the Australian Grand Prix in 2022 that the three tire options are non-consecutive. At that race, the C2 was the hard, the C4 was the medium, and the C5 was the soft."
"Pirelli believes that this selection will make a two-stop strategy the favorable approach. Last year, the C2 tire was designated as the hard compound, with the C3 serving as the medium and the C4 as the soft. George Russell crossed the finish line in P1 after executing a daring one-stop strategy, pitting on Lap 10 for a set of C2 hard tires and making those last until the end of the race."
