Tyre temp after a spin (LMDH)

    I just recently had a spin during a race driving the BMW LMDH at Silverstone.

    After that, all tyres went "red" temps in the gauge, the car became undrivable, and there was nothing I could do to fix it. I basically had to pit for tyres, although they were not wore out, just too hot.

    It doesn't seem realistic and I never experienced it with other cars in the sim.

    Any ideas?

    Thanks in advance.

    Perfectly normal phenomena. To cooldown the tyres again you've to drive a tad slower and turn up TC to it's highest position. Also keep in mind you tyres could been burned out and lost a lot of performance, so a pit for fresh tyres would been desirable as well.

    Well, I will test it again when possible to see if the TC helps. I did change pace, and it wasn't enough.

    But pitting for tyres when the gauge doesn't show that they have been worn out doesn't seem to make sense.

    depending on the nature and distance of the spin and if you tried to arrest the spin with brakes fully engaged.
    You may well have flat spotted some or all tyres .

    I wonder if, as Kuku said, could it be the games way of simulating a flat spot? Since there is no real way to graphically show this, maybe it just sets the tires to a high temp? Just tossing out ideas.

    I don't think so - if you try e.g. a Formula Classic and brake hard it is easy to flat spot - I don't remember anything like that happening as you describe

    The default hud doesn’t really show it , but I do see it on third party dashboards with tire monitoring. If you over stress the tire through lock ups or fast spins it can show on display as flickering tyre and noticeable tyre temp change.

    and fellow league racers have verbally made comments about the grip being poor for a while after they have had a big spin , so part of it is potential flat spots or just generally cooked and blistering tyres .
    I’ve also had it happen to me in a V10 g2 race , where I was turned around at high speed , but made no barriers or had any recorded damage, but I spent the rest of the stint wondering why I was second's off the pace . then I pitted for tyres and pace was restored.

    TLTR..
    Tyre damage is a thing

    I recently upgraded my t150 to a r9 and I was very impressed about how clear I feel the flat spots. It wasn't something I was expecting honestly, and it took me a while to actually realize what was what I was feeling through the wheel. Since them I feel like, whenever I have a flat spot, I have less grip than if there wasn't any flat spots but the overall condition in the UI were the same

    Graphically you've just given me an idea - on the tyre temperature/wear indicators you could have for example a black band or something that gets darker/larger depending on the severity of flat-spotting on the tyres.

    I do also notice flat spots in FFB (unless I'm just imagining things) but with all different wheelbases out there everyone's mileage may vary.

    I have an 8x8 led matrix with tyre info (temp and wear) and also noticed it there (like an external dashboard) but this is also visible in AMS2 "technical" HUB, the one that shows tyres in big format (a pity it does not allow for resize).

    All FFB based on physics engine rack forces (like defaults ones and my FullFFB, for instance) have real flatspots ("real" like they came from the physics engine, although I don't know how they are produced internally).

    I've got a page on my SimHub display panel that shows detailed tyre temperatures.
    There are actually 9 different temperatures for each tyre shown in shared memory. As well as the average temperature and L.M.R. shown on the HUD there is Surface, Tread, Carcass, Air and Rim temperatures.
    Flat spots are of course tyre dependant, as softer tyres are easier to flat spot than hard ones.
