    I’ve read the cars used Michelin tires:
    https://michelinmotorsport.com/var/...lication/8d7440a83ebc33dd7f4241255aad147f.pdf

    “These latest-generation simulators allow the fitment to the cars of ‘virtual’ tyres that have been conceived entirely digitally to commence testing with the drivers before moving on to the track
    testing phase.“


    The virtual MICHELIN Pilot Sport range consequently promises to be not only a frequent talking point over the weekend, but also one of the keys to providing an entertaining inaugural Le Mans 24
    Hours Virtual.
    Participants will be able to choose between four different types of tyre:
    • The MICHELIN Pilot Sport Soft (qualifying and single stinting)
    • The MICHELIN Pilot Sport Medium (approximately two stints)
    • The MICHELIN Pilot Sport Hard (approximately three stints)
    • The MICHELIN Pilot Sport Rain (wet conditions)”


    But I’m not sure what it means. Was it only visual branding, but with the same physics as used in the game?
    Michelin has industry leading virtual tire technology:

    I highly doubt they would build, integrate and test different tires just for the race. It’s not that simple to swap tires in rF2.
    Perhaps the current ones, used in rF2 endurance cars(and GT3) use to some extent Michelin TameTire technology?

    The tires in the endurance pack have always been Michelin-branded, and S397 have always tried to make the tires close to the real ones, within the limits of the model. If they had gotten something like that from Michelin, there would have been a big announcement years ago already.

    After they went to Duqueine they remade their tires if I'm not mistaken, they are all based on Michelin then (considering the cars ran by that team). Ofc this is not "official Michelin" afaik.
    Michelin did say they are degrating way too fast tho, this has been a complaint for a long time, as always S397 will take ages to fix

    Here is the actual statement from Michelin post race:

    An even more detailed understanding of our ‘virtual’ tyres
    The drivers were swift to acclaim Michelin’s tyres after qualifying and their praise continued during the race as they paid tribute to the realism of the feedback replicated via the steering wheel, and notably the difference between the feeling of the different compound options. As in the real Le Mans 24 Hours, their strategies were based on the use of either hard or medium tyres during the early stages of the race, before switching to the softer option for the cooler hours of darkness. On Sunday morning, as the temperature started to climb to exceed 20°C again, they returned to the medium compound, and then the hard tyre. In contrast to the real Le Mans 24 Hours, however, where multi-stinting the same set of tyres is commonplace, this tactic wasn’t a feature of the virtual race. This was due on the one hand to the fact that the teams didn’t have a maximum allocation of tyres for the race, whereas numbers are capped in the real world. On the other, the simulated time allowed for tyre changes was relatively short, so there was little to gain from staying on the same rubber for more than one stint. Meanwhile, the wear rates factored in by the software were higher than in reality. The game effectively reproduced a cost of two seconds per lap (one stint equivalent to approximately 10 laps) due to wear, whereas – in reality – Michelin’s tyres deliver consistent lap times from the start to the end of runs of up to four stints at a time. Michelin hopes to be able to work with the rFactor2 platform’s designers so that competing teams have a broader spectrum of possible strategies in the future while demonstrating the consistency of its tyres’ performance more fully.

    All of this is great. The more direct manufacturer integration and data into rF2, the better for us.

    I recall reading it. This seems very excessive tire wear. Two seconds per lap? So they modified realtime section of tires for the LM24 Virtual race? Because in public rF2, tires in the Endurance pack cars do not wear so fast .

    Anyway, so the tires for the Endurance pack(and used in GT3 packs) and were developed in based on Michelin data and with cooperation with them?
    I hope they will continue working closely to keep improving the tires in rF2. Maybe they will incorporate some of the TameTire technology.

    2 seconds difference between new tyres and old tyres.

    They do, has been a complaint for a while. Ofc the aliens noticed this first since they get hit by it more lol but it's not 2 second per lap drop, it just drops 2 seconds in a few laps

    The rfactor2 tire looks very good to me, you pay dearly for driving errors (overheating, blockages, spinning tops) that accelerate the degradation and loss of performance of the tire just like in real life

    Michelin disagrees

    I’m not sure I understand. So they meant in rF2 used tires were 2 seconds slower than fresh, but in reality times are consistent whole stint? Maybe if it’s only 10 laps then difference would be small, due to less fuel.

    So when do these Michelin tires degrade if ever?
    After 40 laps?

    For them it is bad publicity to have tires shown to be degrading so badly, even though it is virtual, it is represented as close representation of reality, which it should be. Michelin claim is also easily backed up by real life tires performance. There was a thread regarding this here in forums not long ago.

    The mediums should last 4 stints in cool weather. Warmer weather increases track heat, which increases the tire heat....less tire life.
    About 10 years ago, Michelin had a supersoft street tire that would last an entire 2.5hr street race for ALMS cars. Detroit, if I recall correctly, the winner only pitted for fuel, no tires.
