Barcelona GP tyre battle: Leclerc sets the long-run pace as degradation reshuffles the order
Barcelona set for a decisive tyre fight
The Barcelona-Catalunya Grand Prix is developing into a pure tyre-management contest after Friday’s second practice exposed severe degradation across the field. Long-run simulations late in FP2 showed drivers losing as much as five seconds over ten laps, even on the C3 compound, which is the medium tyre this weekend.
That level of drop-off threatens to distort the competitive picture. One-lap speed still matters, but the race may be defined by who can keep the rear tyres alive for long enough to make strategy work.
Ferrari finds a potential race-day weapon
Charles Leclerc ended Friday with the strongest long-run profile for Ferrari. The Scuderia has brought eight upgrades to the SF-26 in Spain, a package that was already a key storyline in its major Barcelona upgrade push. On the evidence of the race simulations, Ferrari may also be benefiting from a familiar trait: a car that can struggle to switch tyres on quickly, but then appears to suffer less degradation over a stint.
Once stint length and tyre compound differences were accounted for, Leclerc was 0.16s per lap quicker than Mercedes driver Kimi Antonelli. Lewis Hamilton, however, was 0.83s off the adjusted benchmark, while George Russell was 1.4s adrift, underlining how uneven the picture remains within teams as well as between them.
The result is striking because Barcelona has recently been a more difficult venue for Ferrari, while Mercedes and McLaren have tended to look stronger. McLaren, the reigning world champion team, was 0.39s per lap slower on average in the long runs and also struggled with degradation, although both McLaren and Mercedes appeared stronger over a single lap.
Red Bull and the midfield face a mixed picture
Red Bull remains hard to read. Max Verstappen was only sixth in qualifying simulations, while the team’s long-run pace, 0.45s off, was broadly in McLaren territory and behind Ferrari and Mercedes. Red Bull looked competitive in the high-speed first sector but lost time through the corners. Ferrari was weaker on the straights but gained heavily in sector two, while Mercedes and McLaren appeared more balanced across the lap.
In the midfield, Racing Bulls and Audi continued their Monaco form. Arvid Lindblad was seventh in FP2, Gabriel Bortoleto eighth, and Audi also looked solid over race runs. Nico Hulkenberg produced the best midfield long-run average, 1.02s off the front, comfortably ahead of Haas driver Oliver Bearman, who was nearly two seconds down.
Pirelli expects at least two stops
Pirelli’s softer selection of C2, C3 and C4 compounds has intensified the strategic challenge. Dario Marrafuschi told Sky: “We wanted to encourage more pit stops, at least more than one. We expected two stops, but under these conditions tyre degradation is becoming very severe.”
He added: “The rear tyres are overheating significantly, making life extremely difficult for the drivers. On Sunday, at least two pit stops will probably be necessary – everything beyond that will depend on the conditions.”
For now, Barcelona has no clear favourite. It has a tyre crisis, and whoever solves it first may control the Grand Prix.
