    Hi,
    often we feel the need to test a setup with used tyre, it would be possible have the possibility to set a percentage of tyre wear at pit exit?
    Thanks.

    Since thermal degration, core/carcass temperatures and pressure buildup are all even more important than tyre wear %, then this option would not be objectively useful for any testing purposes.

    Maybe it works if you use the "continue" feature on replays though which allows you to drive offline at any point in a replay of a previous session?

    Interesting idea. I think it would be an awesome feature to 'save' a set of used tyres for later use.

    It is way more complicated that just a percentage of wear in the case of rfactor. No used tyre is the same because of the way rubber actually disintegrates - your used tyres are actually lighter than the ones you start with, and this isn't radially symmetrical disintegration - the whole 3d model is being eaten away at at different rates. This is why you can feel the flat spots. Add to this the thermal degradation at all the different points and what you have is a big rubber pie of complexity.

    I don't see a reason that they can't 'snapshot' the tyre as a future update feature, but yeh this is absolutely not something you can do or even simulate in dev mode.

    ...but the setup? do you mean that it can be loaded a different setup, using that feature?
    However I think that starting from low percentage it should be not so bad.

    The way tires are created for rf2 means that there's not a way to have the 3d rubber imperfections already in the tread. The % you see in game is just the average abrasion around the tyre (% of tread left), but you also have imperfections and thermal degradation, which usually account for most of the 'wear'.

    You can't do this with a different setup either.

    If you start an experimental run and just start a run with say, 50% tread, you'll have way more grip than if you run the tyre from 100% until it says 50% tread left in game, because the later will have the other main degradation factors too, and they can't just be separated out because they are completed infused throughout the life of the tyre. It would be a completely pointless exercise.

    The only way this can be done would be if S397 include the ability to save a used tyre in an update. And I think this is reasonably likely to be added at some point because it is a feature of endurance racing.

    The thing to take away from this is '% wear' really means '% tread left', which is usually the least important factor to how worn the actually tyres are.

    OK, understood, the tyre model is complex, I know. But perhaps, since we're talking about digital things, S397 could elaborate some algorithm simulating most usual situation of degradation. :D

    IMHO the way to do this is to save the parameters of every node of the tyre and load this state in the pitstop or garage.
    But the thing is more complex to implement, because S397 will have to add a limit of amount of tyres of every compound during the weekend (or race day or practice, championship, etc) and away to choose the desired set of wheels. Furthermore, this has to be controlled in offline and online, then there has to be a server side and a client side.

    @lagg exactly what we need :) Let's simulate real life, more.

    :) It is like the fans of the Nordschleife who call it the greatest circuit in racing, but then want to SKIP the outlap, which deprives them of ANOTHER lap around the greatest circuit in racing.
    btw, wasn't there an app released a year or two ago that did indeed run the tire down to X%? (or was that rF1?)
