    As i couldn`t find any information regarding GT4's: I'm training for a league race on Monza for a race on friday. So i feel like i can really compare between before and after the patch. There really is a difference in feel. But as i'm reading the thread here, this has not to do with the DHE tires since there is no DHE for the GT4, is that right? Eventhough, i experienced on longstint runs, that the sudden drop off of grip after a couple of laps is less significant and the performance during the stint seems more stable. Which in my understanding should be a feature of DHE?!
    The training server of the community is set on 2019, as the admins said.

    It should be DHD2. The shower wear, which you experiencing ,is probably thanks to new tire physics improvements.

    New tyres and physics feel great on the Audi Evo. It is a bigger change than I thought it would be.

    Excellent work Aris!

    Q: If I choose the 2015 Audi R8 LMS on a 2020 MP server do I get get the new DHE tyres..?

    @WallyM - G'day Wal.. :)

    Thanks mate that clears that up.. I was a little confused by that one. I thought it may have only been for none Evo cars that also competed in 2020 alongside it's Evo sister car.. The Audi were all Evo's in real life so I was not sure about this dinosaur in ACC..

    Really enjoying the new handling, ACC just becomes more and more addictive with each new update.

    I have a question regarding kerbs and loss of tyre pressures with the new tyre model. I was in an offline practice session with AI at Zolder. My tyre pressures were good at around 27.6 but then started to drop off after about 10 laps but ambient and track temperatures remained constant. I looked into Motec and saw a loss of pressure relating to riding kerbs. It was the final chicane at Zolder and I did not hit it hard as I was pretty consistent throughout the session . There was no loss of pressure in 1 lap where I hit the chicane on the back straight pretty hard. I never had a problem with the previous tyre model.

    Is this now a feature in the new model that you cannot ride kerbs with normal tyre pressures?

    It always has been like this. Obviously the correct pressure keeps the tyre in place... but it can still happen if the tyre gets a big spike to release some pressure. The risk is very low, but as you witnessed, it can still happen. Because the whole effect is not scripted but dynamic, there's always a risk of riding certain kerbs very aggressively, as it could happen in real life.

    So to answer your question: "can I lose pressure on kerbs even with correct pressures?"
    answer: "highly improbable, but there's always a risk."

    Thank you! This question came up already some times. Now we got the answer. :D
    Absolutely awesome, that even this is dynamic and not a canned effect.

    This tyre model thing is a big change on both cars I tried (Porsche and Audi Evo). You lose the rear more easily both on braking and on throttle. I still use the aggressive setup but now I put the BB more forwards and increase TC by 1 notch. Otherwise it's just disaster on, in particular, the slow corners. I'm quite a bit slower, but I think I'm not the only one struggling if I look around :)

    Is losing the rear because of the tyre change, or the yaw aero change?

    I don't know, it's mainly a low speed / medium speed thing for me so I thought it would be something mechanical. Then again the slow corners have the biggest jaw angles... I just find the change quite pronounced.

    Any word on when we can expect the update to the IGT tracks to use the new tyre?

    why do you expect it to be an update? It could also be a new dlc "IGT 2020", couldn't it?
    New/modified tracks, new cars, new liveries...

    hello,

    Is there a chance that car setups get update? For now I was casually driving aggressive sets (I don't have much hours in ACC). But with new tires model it's like "drift fest" :/

    I do seem to find it is easier to get the car to have a slight, easily controllable oversteer/drift in some corners.

    Which I rather like, feels RL, and helps the car rotate in some corners, and although maybe not fast,... its FUN. :D
