Ferrari face a crucial tyre strategy decision ahead of the 2026 United States Grand Prix, with Charles Leclerc and Lewis Hamilton holding different sets of fresh tyres for Sunday’s 56-lap race at the Circuit of the Americas. Although Kimi Antonelli starts from pole position, Mercedes, Ferrari, Red Bull and McLaren are separated by less than eight tenths of a second in estimated race pace, leaving pit stops, tyre degradation and possible Safety Car periods as potentially decisive factors.
The most interesting question for Ferrari concerns whether to split the strategies of its two drivers. Charles Leclerc has one fresh soft tyre set available, while Lewis Hamilton has no unused softs remaining. That difference could allow the Monegasque to adopt a more aggressive approach at the start, whereas the seven-time world champion appears better positioned for a conventional medium-to-hard strategy.
Sunday’s race is expected to favour a single pit stop, but the calculations suggest that a two-stop approach is not far from becoming competitive. With the leading teams relatively close on estimated long-run pace, even a small difference in tyre degradation or the timing of a neutralisation could change the outcome.
United States GP strategy: Ferrari’s tyre choices could prove decisive
The remaining tyre allocation immediately creates different strategic opportunities among the leading teams. Mercedes and McLaren have exhausted their fresh soft sets, while Red Bull still has two unused sets per driver. Ferrari has only one fresh soft remaining, allocated to Charles Leclerc.
That could make the opening laps particularly important for the Scuderia. Charles Leclerc starts fourth and Lewis Hamilton fifth, directly behind Isack Hadjar, with both Ferrari drivers potentially able to challenge the Red Bull into Turn 1.
Ferrari’s decision will depend partly on whether the advantage of starting on the soft compound outweighs the risk of increased degradation later in the race. The tyre degradation concerns identified for the United States Grand Prix make that calculation particularly important.
There is also a championship dimension. Kimi Antonelli leads the Drivers’ Championship with 340 points, holding a 102-point advantage over George Russell and a 111-point lead over Lewis Hamilton.
The Mercedes driver could mathematically secure the title in Austin, but only by winning while George Russell finishes ninth or lower and Lewis Hamilton fifth or lower. With Russell starting sixth and Hamilton fifth, that scenario would require both challengers to endure particularly disappointing races. The possibility exists, although the circumstances make it unlikely.
Austin weather forecast: wind, track temperatures and possible rain
Formula 1’s weather forecast for the United States Grand Prix indicates ambient temperatures between 19°C and 27°C, with a 20% chance of rain associated with an approaching storm system. Southerly wind gusts could reach between 35 and 40 km/h during the afternoon.
The weather represents an important variable for every strategy calculation. If the radar begins indicating rain around the scheduled start, conventional pit-stop windows could quickly become irrelevant. Starting positions would become less decisive, while the availability of fresh slick tyres, including at least one hard and one medium set for every driver, could gain importance if conditions subsequently allowed their use.
Wet conditions could also increase the likelihood of Safety Car or Virtual Safety Car periods. Strong winds, meanwhile, appear particularly likely after already influencing qualifying. More powerful gusts could make braking into Turn 12 especially difficult. Track temperatures reached between 40°C and 43°C during FP1 and FP2 before falling to between 36.7°C and 40°C in qualifying. The race forecast suggests a peak slightly below Saturday’s maximum.
That would make conditions cooler than in previous editions of the event, potentially helping to limit tyre degradation despite Pirelli bringing compounds one step softer than those used in 2025.
The track has also developed significantly throughout the weekend. Lap times improved by 0.65 seconds between FP1 and FP2 and by another 0.83 seconds between Q1 and Q2. However, improvement slowed to just 0.16 seconds in Q3, when track evolution effectively stopped.
Consequently, drivers will start the race on a surface that is already well rubbered-in, with tyre wear remaining one of the main concerns.
Why Turn 12 could become Ferrari’s biggest problem in the race
Overtaking opportunities at the Circuit of the Americas are concentrated in a relatively small number of areas. Turn 1 features an uphill approach at more than 300 km/h before drivers slow to approximately 87 km/h, with the wide track creating opportunities to attack under braking.
Turn 12 provides another major overtaking opportunity after approximately one kilometre of straight. Drivers brake from around 331 km/h to 79 km/h over roughly 100 metres. Turns 11 and 15, along with Turns 19 and 20, offer additional possibilities.
However, the section between Turns 11 and 12 could be particularly difficult for Ferrari because of its straight-line speed deficit.
Along this straight, battery energy can be depleted in approximately 12 seconds, with practice data indicating speed reductions of between 12 and 18 km/h before the braking zone.
Under the 2026 overtaking system, a driver within one second of the car ahead at the detection point can receive an additional 0.5 megajoules of energy and deploy 350 kW up to 337 km/h. The assistance available to the leading car diminishes beyond 290 km/h, providing the pursuing driver with a potential advantage towards the end of the straight.
But the cars do not approach Turn 12 with equal underlying performance. During qualifying, Kimi Antonelli reached 341 km/h compared with Charles Leclerc’s 326 km/h, while Ferrari lost approximately 0.390 seconds across the straights, the largest deficit among the four leading teams. That makes a Ferrari defending into Turn 12 potentially vulnerable, even if the car performs strongly through the preceding corners. The same weakness could complicate overtaking attempts against faster cars.
The problem was already evident in Ferrari’s Austin practice performance analysis, which highlighted the contrast between the SF-26’s improved downforce and its straight-line limitations.
Drivers must also manage the circuit’s uneven braking surfaces, which increase the risk of wheel lock-ups. Track-limits violations at Turns 12, 19 and 20 could produce warnings or penalties, particularly when drivers are unsettled by the bumps.
Plank wear is another consideration. During the 2025 event, Ferrari instructed Lewis Hamilton to lift off the accelerator on Lap 29 because of concerns related to plank wear.
Pirelli tyre compounds: why the 2026 hard resembles last year’s medium
Pirelli has selected the C2 as the hard compound, the C3 as the medium and the C4 as the soft for Austin. This selection is one step softer than the allocation used in 2025.
Each driver receives 13 sets for the weekend, comprising two hard, three medium and eight soft sets. During the 2025 United States Grand Prix, the medium tyre produced an average stint length of 29 laps, while the soft averaged 24 laps. Assuming the compounds themselves remain comparable, this year’s hard should offer endurance similar to the 2025 medium, with the current medium behaving more like last year’s soft.
Practice data suggests that the soft was approximately 0.6 seconds faster than the medium, while the medium held an advantage of around 0.5 seconds over the hard. However, outright lap-time performance is only part of the calculation. Teams must consider how quickly those advantages disappear as the tyres accumulate wear. The long runs from FP2 produced significantly different degradation figures. Charles Leclerc’s soft tyres lost 1.28 seconds across 11 laps, while Max Verstappen’s softs lost 0.56 seconds over the same distance.
Franco Colapinto recorded degradation of just 0.18 seconds over seven laps on softs, while Kimi Antonelli’s medium tyres lost 0.86 seconds across nine laps.
These variations make it difficult to identify a single degradation pattern that applies equally to all teams. The anticipated stint lengths are approximately 22–26 laps for the medium compound, 30–34 for the hard and around 20 laps for the soft.
Those figures form the basis of the expected race strategies, with additional compound and stint comparisons available through the ScuderiaFans F1 tyre and stint analysis.
One-stop versus two-stop strategy: the numbers behind the Austin race
The baseline strategy for the 2026 United States Grand Prix is a one-stop race using the medium and hard compounds. Under that approach, the ideal pit window is expected to fall between Laps 22 and 26.
An alternative involves starting on the hard compound before switching to mediums around Laps 30–33, potentially providing stronger performance during the closing stages.
Starting on soft tyres and finishing on mediums or hards is also considered credible, although its effectiveness depends heavily on the degradation experienced during the opening stint.
A two-stop soft-medium-soft strategy represents another possible approach, with calculations suggesting that its total race time could remain relatively close to the preferred one-stop option. The estimated time lost during a normal pit stop at Austin is 21.3 seconds compared with remaining on track.
For a two-stop strategy to become faster than a single stop, tyre degradation would need to reach approximately 0.082 seconds per lap of tyre age. The current estimate is 0.065 seconds, which places the expected conditions on the one-stop side of that threshold.
Fresh tyres are estimated to offer an average advantage of 1.4 seconds per lap over used tyres. However, that does not automatically guarantee a successful undercut, particularly when traffic, tyre warm-up and the timing of rival stops are considered. Historical data suggests that drivers running close together should avoid delaying their pit stops unnecessarily.
The remaining tyre sets further restrict the available options. Mercedes and McLaren have no fresh softs, making medium-hard the most straightforward strategy unless they choose to reuse an older soft set.
Red Bull can consider starting on fresh softs, whereas Ferrari has that option only for Charles Leclerc. The Monegasque driver used a soft-tyre start in the 2025 United States Grand Prix and went on to finish third.
Safety Car probability: how a neutralisation could transform the strategy
Neutralisations have been relatively common in recent editions of the United States Grand Prix. Across seven races, five featured at least one neutralisation, with two involving a Safety Car and three featuring a Virtual Safety Car.
That corresponds to historical frequencies of approximately 29% for a Safety Car and 43% for a Virtual Safety Car. In those examples, neutralisations occurred before Lap 28. The current estimates place the probability of a Safety Car at 40% and a Virtual Safety Car at 55%, with the overall chance of at least one neutralisation around 70%.
However, the timing matters as much as the occurrence itself. A pit stop during a Safety Car or Virtual Safety Car is estimated to cost approximately 10 seconds, substantially less than the normal 21.3-second pit loss.
If a neutralisation arrives between Laps 22 and 33, it could benefit drivers who have not yet stopped while disadvantaging those who have already completed their mandatory tyre change. The race leader can be particularly vulnerable because a full Safety Car eliminates the gap previously established over the chasing pack. An early neutralisation before Lap 22 could instead force teams into a very long hard-tyre stint of 40 laps or more, potentially changing the original strategy calculations.
A late neutralisation would create a different opportunity. Red Bull’s fresh soft tyres could become especially valuable for a final attack, given the compound’s estimated 0.6-second advantage over the medium.
For Ferrari, the implications would depend on whether Charles Leclerc’s unused soft set had already been used and how much tyre life remained available to both drivers.
Ferrari’s race pace: why the SF-26 faces a difficult challenge
Although Ferrari demonstrated impressive single-lap performance in practice, the estimated long-run figures paint a less encouraging picture.
Calculations based on Friday’s race simulations place Mercedes at the front, followed by McLaren at 0.44 seconds per lap behind, Red Bull at 0.64 seconds and Ferrari at 0.79 seconds. That would make Ferrari the slowest of the four leading teams on estimated race pace, despite its encouraging qualifying potential.
The contrast is particularly interesting because the theoretical qualifying lap placed Ferrari second with a 1:34.028, while McLaren ranked fourth with a 1:34.402. Over longer runs, however, their positions are reversed.
During FP2, Red Bull appeared to manage the soft compound more effectively, while Mercedes was able to maintain a pace on mediums comparable with rivals running soft tyres. Lando Norris recorded the strongest long run on the hard compound, averaging 1:41.152, followed by Charles Leclerc and Max Verstappen on softs.
These comparisons are central to Ferrari’s prospects. The team has demonstrated strong cornering performance, but sustaining competitive lap times over longer stints could prove more difficult.
Ferrari’s Austin upgrades and the strategic choices for Charles Leclerc and Lewis Hamilton
Ferrari introduced a revised floor and a development package divided into four main areas for the Austin weekend. The updates helped the Italian team lead all three free practice sessions, but qualifying ultimately produced fourth place for Charles Leclerc and fifth for Lewis Hamilton.
The SF-26’s performance profile remains consistent with the qualifying analysis. Ferrari gained approximately 0.347 seconds through slow corners on a single lap and around 0.32 seconds in the slow corners during FP2 race simulations. The car was also particularly competitive around Turn 1, but its straight-line weakness remained a major disadvantage, with approximately 0.390 seconds lost over the straights in qualifying.
The estimated race-pace deficit of 0.79 seconds per lap places Ferrari behind Mercedes, McLaren and Red Bull in the current projections.
However, the two Ferrari drivers have different tyre inventories available for the race.
Charles Leclerc has one fresh hard, one fresh medium and one fresh soft set remaining. This gives the Monegasque an opportunity to repeat his soft-tyre start from the 2025 United States Grand Prix.
Lewis Hamilton has one fresh hard and two fresh medium sets remaining. Without an unused soft, the British driver’s most natural strategy appears to be medium-hard.
Both Ferrari drivers could potentially attack Isack Hadjar into Turn 1, and that opportunity may influence the choice of starting compounds. The team’s decision will also need to account for the vulnerability of the SF-26 on the long straight towards Turn 12. Gaining positions at the start may be particularly valuable if overtaking becomes more difficult once the cars settle into their race pace.
Mercedes, Red Bull and McLaren: how Ferrari’s rivals compare
Mercedes appears to possess the fastest car over a single lap, with an ideal team time of 1:33.843 and particularly strong performance through high-speed corners.
Nevertheless, the team left approximately 0.192 seconds unused compared with its theoretical potential and lost between 0.18 and 0.30 seconds in the braking area for Turn 1 and the final section of the lap.
Mercedes also leads the estimated race-pace rankings, but each driver has only one fresh hard and one fresh medium available, with no unused softs. That makes a medium-hard strategy with a stop between Laps 22 and 26 the most straightforward approach.
Red Bull demonstrated greater qualifying efficiency, losing just 0.088 seconds compared with its theoretical ideal lap. The team also gained approximately 0.273 seconds on the straights relative to the average of the four leading constructors, although it lost 0.278 seconds in slow corners.
That straight-line strength could be particularly valuable at Turn 12, both when defending and attacking.
Red Bull ranks third in the estimated race-pace comparison, 0.64 seconds behind Mercedes, but possesses the most flexible fresh-tyre inventory among the leading teams. With two unused soft sets per driver and encouraging degradation figures, an early soft-tyre stint or a two-stop strategy remains a realistic alternative.
McLaren starts further down the grid than its estimated race pace would suggest. Oscar Piastri qualified seventh and Lando Norris eighth, but the team’s projected race deficit is only 0.44 seconds per lap, placing it second behind Mercedes.
That estimate is supported particularly by Norris’s long run on hard tyres in FP2.
McLaren’s theoretical qualifying deficit was much larger, at 0.559 seconds behind Mercedes, including losses of 0.239 seconds through fast corners and 0.113 seconds in slow corners.
Track limits have also been a recurring problem. McLaren recorded 26 deleted lap times during practice, more than any other team, while Norris lost a Q3 lap at Turn 19.
Like Mercedes, McLaren has no fresh soft tyres remaining. Norris has two fresh mediums, while Piastri has one, and the team’s hard-tyre long-run performance suggests that compound could play an important role in its race plans.
Isack Hadjar starts third despite Red Bull ranking behind Mercedes and McLaren in the projected long-run order. Liam Lawson is another driver starting ahead of his car’s estimated pace, qualifying ninth with a projected deficit of 1.60 seconds per lap.
George Russell and Lando Norris, by contrast, start further down the order than their cars’ estimated performance might suggest.
United States GP favourites: Antonelli leads but Verstappen has strategic options
Kimi Antonelli starts as the favourite after securing pole position, but Max Verstappen is expected to challenge immediately, potentially targeting Turn 1.
Red Bull’s remaining fresh soft tyres offer additional flexibility, including the possibility of a more aggressive starting strategy.
Lando Norris could also become a factor from eighth place because of McLaren’s strong hard-tyre long-run performance. George Russell, meanwhile, has a competitive Mercedes and could benefit from a well-timed neutralisation.
For Ferrari, the challenge is more complicated. Charles Leclerc and Lewis Hamilton start close enough to the front to consider an early attack, but the projected race-pace deficit and straight-line limitations could make sustaining those gains difficult.
Three possible United States GP race scenarios
The baseline scenario is a dry race featuring one pit stop and no more than one Virtual Safety Car.
Under this projection, Kimi Antonelli and Max Verstappen would fight for the lead around the pit-stop window between Laps 22 and 26. Mercedes could stop first if Red Bull is within two seconds, using the undercut to defend track position.
Charles Leclerc and Lewis Hamilton could recover positions at the start but might remain behind the leading Mercedes and Red Bull cars because of Ferrari’s straight-line weakness. Lando Norris and George Russell could make progress through their stronger projected race pace.
The estimated winning race time under those conditions is approximately one hour, 35 minutes and 20 seconds.
The alternative scenario involves either a Safety Car or a two-stop race.
A Safety Car between Laps 22 and 33 would favour drivers who had not yet stopped. An earlier neutralisation could create an extremely long hard-tyre stint, while higher-than-expected degradation could make two stops more competitive.
In that situation, Red Bull’s fresh soft-tyre inventory could provide an important opportunity to attack.
The most disruptive scenario involves rain or a chaotic opening lap that removes one of the front-running cars from contention.
Wet conditions would substantially reduce the importance of the original grid positions and force teams to reassess their strategies. The decisive factor could become the timing of tyre changes rather than the original one-stop or two-stop calculations.
A brief shower during the race would create an intermediate scenario, potentially rewarding the drivers who switch to intermediate tyres at the right moment and making the original dry-weather strategy calculations irrelevant.
What Ferrari must get right during the 2026 United States Grand Prix
The central strategic question concerns a race that appears to favour one pit stop but remains close to the threshold at which two stops could become competitive.
Mercedes, McLaren, Red Bull and Ferrari are separated by approximately 0.8 seconds in estimated race pace, meaning pole position is an advantage but far from a guarantee of victory.
Neutralisations are estimated to be more likely than not, particularly during the first 28 laps, while the remaining fresh-tyre inventory could determine which teams benefit most from unexpected developments.
Ferrari combines some of the strongest first-lap and slow-corner performance with the weakest straight-line figures and the slowest projected race pace among the leading four teams. That creates a clear incentive to attack early wherever possible.
The opening lap will therefore be particularly important. Attention will focus on the duel between Kimi Antonelli and Max Verstappen, the opportunities available to Charles Leclerc and Lewis Hamilton against Isack Hadjar into Turn 1, and George Russell’s position after the start.
Turn 12 will also demand close attention, particularly given the potential for braking difficulties and the contact that occurred there during the 2025 race.
The first pit-stop decision could then shape the remainder of the Grand Prix. A stop before Lap 22 could indicate an undercut attempt or a response to a neutralisation, while Red Bull’s compound choice and the length of the second hard-tyre stint may influence how the leading teams approach the closing stages.
For Ferrari, the most important decision may arrive even before the lights go out: whether to give Charles Leclerc the aggressive soft-tyre start that Lewis Hamilton cannot replicate with a fresh set, or adopt a more conventional approach with both cars.
With the SF-26 showing impressive cornering speed but struggling on the straights, the Maranello team must find the right balance between gaining positions early and protecting tyre performance over 56 laps. The opening exchanges, first pit-stop window and any Safety Car intervention could ultimately determine whether Ferrari can turn its encouraging Austin developments into a stronger race result.
