Nonetheless, whereas qualifying is all in regards to the one-lap tempo on the comfortable compound, the Chinese language Grand Prix will likely be all about race tempo on the mediums and the hards. All through this week tire degradation, because of the newly resurfaced circuit in Shanghai, has been a significant factor. That was the case within the F1 Dash race on Saturday, as Lewis Hamilton ran away from the sphere in clear air whereas these behind him struggled to maintain their medium tires in the fitting window over simply 19 laps.
How the drivers deal with 56 laps is a totally totally different query.
Pirelli, F1’s unique tire provider, believes {that a} two-stop technique for the Chinese language Grand Prix is “compulsory,” however how every driver will get house continues to be matter of debate.

What are the tire methods for the Chinese language Grand Prix?
As famous above, tire degradation has been an enormous situation for the drivers this week. Whereas the circuit in Shanghai has been resurfaced for this season, resulting in elevated grip for the drivers, the brand new floor has additionally seen drivers tear by means of tires on prolonged runs. For instance, in the course of the F1 Dash race Max Verstappen was attempting to chase down Hamilton on the entrance, however by Lap 14 Verstappen advised his crew that his medium tires have been “useless.”
With 56 laps on faucet for Sunday, and medium tires carrying out after simply 14 laps or so, you may see why Pirelli believes a two-stopper is the trail for groups to observe.
“As for technique, the extent of degradation leads us to counsel {that a} two-stop is compulsory, that includes the Medium and the Onerous,” mentioned Mario Isola, Pirelli’s Director of Motorsport, of their recap of Saturday’s motion.
Listed here are the three predominant choices for groups and drivers, as outlined by Pirelli:
The 2 most well-liked methods from Pirelli characteristic the medium and the exhausting, each with groups beginning on the medium compound.
Extra on the beginning in a second.
The primary sees groups begin with the medium and change to the exhausting for the second stint, however there are alternatives accessible beginning there. Within the first choice groups will look to run round 12 to 18 laps on the exhausting compound, earlier than pitting once more for one more set of hards to go the space.
Within the second choice, groups begin on the mediums and change to the hards, extending that second stint a bit to round 14 to twenty laps. Then they’d change to the mediums on that second cease, hoping the softer rubber will enable for faster instances over the ultimate stint, which might run round 12 to 16 laps.
That’s potential, given what we noticed over the 19-lap F1 Dash race, however would require some tire administration from the drivers. Nonetheless, that technique may not be accessible to 1 crew, which we’ll talk about in a second.
Then there’s the third technique, which has drivers begin on the softs for round 8 to 14 laps, earlier than ending with a hard-hard mixture. This may be the play for groups hoping to select up spots in the beginning on the softer rubber, and we’ll dive into that extra in a second.
There’s additionally another choice accessible to groups not proven right here, which is beginning on the hards and working lengthy, hoping for intervention within the type of a security automobile. Drivers in the back of the grid — you Liam Lawson — may make use of this technique within the hopes of choosing up observe place as different drivers are compelled to pit early on softer compounds, after which capitalizing on any alternatives that come up.
Isola talked about that risk in Pirelli’s recap of Saturday’s motion.
“In actual fact, these beginning close to the again may go for the Onerous to increase the primary stint so long as potential, earlier than making up locations within the run of pit stops,” mentioned Isola.
Nonetheless, what tires every driver has left comes into play now.
What tires does every driver have accessible for the Chinese language GP?
Listed here are the compounds every driver has accessible for the Chinese language Grand Prix, in line with Pirelli:
Above we famous that one crew may not be in place to make use of the second choice, which is a medium-hard-medium technique.
That crew? Aston Martin. Each Lance Stroll and Fernando Alonso have only one set of scrubbed mediums accessible for the Chinese language Grand Prix. Provided that, they could have to make use of the primary choice, the place they begin on these scrubbed mediums earlier than ending with a hard-hard mixture.
Or, they might be one of many groups that decide to start out on the softs, earlier than utilizing the hards to shut out the race.
Three drivers — Lawson, Nico Hülkenberg, and Esteban Ocon — every have a pair of latest mediums remaining, which provides them some fascinating choices because the Chinese language Grand Prix unfolds.
You’ll additionally be aware that every driver has a pair of contemporary exhausting tires accessible, one other signal that the groups expect to depend on the C2 exhausting tires within the Chinese language Grand Prix.
Why may the softs be in play on the Chinese language Grand Prix?
As mentioned above even with the excessive ranges of tire degradation, the comfortable C4 compound may nonetheless play a job on Sunday.
Why? As a result of the excessive ranges of grip mixed with the comfortable compound can play an enormous position in the beginning, and groups hoping to select up spots proper when the lights exit may look to the C4 compound to select up these positions.
Pirelli put that in graphic kind right here. As you may see the C4 softs give drivers a transparent benefit in the beginning, as drivers on the softs will attain 150 kilometers per hour faster than these on the mediums, and far faster than these on the hards:
In fact, the tradeoff comes on the finish of the stint, when the grip ranges go away for these on the comfortable compound and they should dip into the pits earlier than anybody on the mediums or the hards.
Nonetheless, for groups with contemporary comfortable tires accessible, that may be an choice. Eight drivers — Lawson, Stroll, Alonso, Pierre Gasly, Jack Doohan, Oliver Bearman, Carlos Sainz Jr., and Gabriel Bortoleto — have contemporary units of softs accessible.
We’ll see what choices the groups go for in a number of brief hours.
