Ferrari’s inability to bring its tyres into the correct operating temperature range proved devastating at the 2026 Brazilian Grand Prix, costing Lewis Hamilton approximately 40 seconds and Charles Leclerc almost 50 seconds across the opening 27 laps. Despite both drivers having fresh engines, the SF-26 struggled in the cool conditions at Interlagos, leaving the team unable to match its leading rivals.
The extent of the damage became clear when the race was divided into its opening intermediate-tyre stint and the subsequent switch to soft slicks. The problems were particularly frustrating because Hamilton had made an exceptional start from the back of the grid, briefly suggesting that Ferrari might have the pace to recover. Instead, tyre temperatures became the defining limitation of the afternoon.
Ferrari tyre problems destroy Hamilton’s remarkable Brazilian GP start
Starting 19th, Lewis Hamilton immediately made substantial progress as the field negotiated the opening corners. By the beginning of lap two, the seven-time world champion had climbed to ninth place, ahead of Max Verstappen in 13th and Ferrari teammate Charles Leclerc in 15th.
The early running appeared to justify the team’s hopes of a competitive race, particularly with both Ferrari cars equipped with new engines. However, the initial optimism quickly disappeared once tyre temperatures began influencing the SF-26’s performance.
With the track temperature at just 26°C, Ferrari struggled to keep its intermediate tyres working effectively. From lap three onwards, Hamilton’s pace deteriorated relative to the cars behind him. The British driver eventually lost a position to Leclerc during the opening stint, despite having established a considerable advantage through his initial recovery.
The contrast with Max Verstappen was especially striking. While the Red Bull driver eventually finished second, Ferrari’s two drivers found themselves losing substantial amounts of time during the early stages.
How Hamilton and Leclerc lost more than 50 seconds combined on intermediate tyres
A comparison with Lando Norris, who went on to win the Brazilian Grand Prix, reveals the severity of Ferrari’s difficulties on the intermediates.
During the opening stint alone, Charles Leclerc surrendered approximately 26 seconds to the McLaren driver, while Lewis Hamilton lost more than 28 seconds. These losses accumulated as the Ferrari struggled to generate and maintain the tyre temperatures needed for competitive lap times.
The problem was not simply a lack of initial grip. The SF-26’s difficulty in reaching the correct operating window prevented the drivers from maintaining a pace comparable to the leading contenders, undermining the positions they had gained or hoped to recover.
The cool track conditions were central to the challenge. When tyres remain below their ideal operating temperature, drivers can struggle to extract the available grip, making the car less effective through corners and limiting its overall performance.
Ferrari’s difficulties with tyre temperatures and the SF-26’s operating window at Interlagos had already emerged as an important technical concern during the Brazilian Grand Prix weekend.
Switch to soft tyres fails to rescue Ferrari as track temperature drops to 24°C
Changing from intermediate tyres to slicks should have offered Ferrari an opportunity to improve its competitiveness. Instead, the switch exposed another weakness in the SF-26’s ability to generate tyre temperature.
With the track registering just 24°C, the Maranello team struggled to bring the soft C5 compound into its effective operating window. Both drivers required approximately ten laps before their tyres began delivering performance comparable to the cars at the front.
That prolonged warm-up period proved extremely costly. Charles Leclerc lost another 22 seconds while waiting for the tyres to reach their working range, adding to the 26 seconds already surrendered during the intermediate stint.
Lewis Hamilton also suffered, although his losses during this phase were smaller. Thanks to the undercut, the seven-time world champion managed to limit the additional deficit to approximately ten seconds.
Nevertheless, the different strategies could not compensate for the underlying problem. Ferrari was unable to extract competitive performance quickly enough from either tyre compound, allowing its rivals to establish advantages that became increasingly difficult to recover.
The contrasting stint performances can also be examined through the F1 tyre and stint analysis, which allows comparisons of compound choices, stint lengths and race pace between Formula 1 drivers.
Ferrari loses almost 50 seconds in just 27 laps at Interlagos
When the two phases are considered together, the scale of Ferrari’s Brazilian Grand Prix difficulties becomes particularly apparent.
Across the opening 27 laps, Lewis Hamilton lost approximately 40 seconds, while Charles Leclerc surrendered close to 50 seconds. Although traffic also contributed to those figures, the inability to bring the intermediate and soft tyres into their operating windows was the central explanation for the enormous deficit.
These losses effectively compromised both drivers’ races before they had reached the halfway stage of their recovery efforts. Even when the SF-26 eventually began producing more competitive lap times, the time already surrendered was too substantial to erase easily.
Without those early difficulties, Ferrari could potentially have experienced a very different afternoon. However, the extent to which the final result might have changed cannot be separated entirely from the time lost in traffic and the circumstances surrounding each stint.
Ferrari faces urgent SF-26 tyre challenge ahead of 2027
The Brazilian Grand Prix reinforced a problem that Ferrari has encountered on other occasions during the 2026 Formula 1 season. The SF-26 can struggle when conditions make it difficult to generate sufficient tyre temperature, preventing the drivers from exploiting the car’s available performance.
The fact that the team experienced similar difficulties with both intermediate tyres and the soft C5 compound made the problem particularly significant. It was not confined to one tyre choice or a single phase of the race.
For the Maranello engineers, understanding why the car requires so much time to reach its optimum tyre window will be an important priority before the 2027 championship. The experience at Interlagos demonstrated how quickly a promising recovery can disappear when tyre preparation becomes a persistent weakness.
Fresh engines had raised expectations for Lewis Hamilton and Charles Leclerc, but the decisive limitation came from another area of the package entirely. Ferrari’s Brazilian Grand Prix showed that competitive power and strong opening laps count for little when the tyres cannot deliver the grip needed to sustain performance.
