PHYSICS Brake ducts and Tyre damage

Let's have it in the setup page first, then we will talk about brake pads. For now their life is "infinite" ok?
The tyre app is pretty straight forward, but the meaning of it I understand might not be, so here are examples:
Blue colour = Cold tyres. Low grip and nervous character. The temperature in ACC doesn't simply changes the grip, but also the general behaviour of the tyre.
Green colour = Optimum temperature range. Good slipangles, good grip.
Red colour = Overheating. A bit less grip, but general "running on honey feel", sluggish slidey, dampened feel.

Now every bar can change colour in the middle which is the core temperature but also in the edges of the bar which is the surface. Normaly the surface of a tyre goes through "flash" temperatures, means it can heat and cool down very fast, not mantaining a stable temperature. That is normal. The main characteristics of the tyre though are given by the core temperature. Both interact, but you can ignore up to a point the surface temp and focus on the core one. It is more important.
Still the surface temps can give you an indication of which part of the tyre gets more heat and thus wears more.
There is no indication of wear. You can only check this when you go back to the setup screen as in real life. You can't check the tyre wear while driving, it is impossible. You will feel it from your laptimes, from a more edgy tyre behaviour, from temperatures getting lower and from experience. Some experienced users might noticed that a very worn tyre might make the gear ratios a tiny tiny tiny bit shorter. Yes we simulate the 3mm tyre depth. A worn tyre is under 1.5mm depth, so you lose 1.5mm of tyre radius too...

The middle bar can go become lower or higher than the other two. This showcases the pressure. If the middle bar is lower, you have less than ideal pressure. If it is higher, you have more than ideal pressure. It is important to check this when the tyres are hot in operative temperature, say after 2,3 laps.
We now also added the actual pressure value in psi, because most cars also have it in the cockpit and they might be poor lost sou... sorry I mean users! that drive from outside the cockpit.
The pressure now are very important, as described my latest blog post. Watch out for pit radio recommendations and act accordingly. A puncture can happen at any time if you're not careful and then your race is over.

The small bars in the inside of each tyre are the brake temperatures. They will go blue during long straights, not an issue. You want them to stay as green as possible during braking. A bit of yellow or orange colour at the end of the braking zone is "ok". Be careful in the relationship between front and rear. If you have your fronts red (overheating) and the rear green, not only you will feel fade and longer braking distances but your brake bias will go backwards because you will have the front brakes fading and the rear ones in optimum braking efficiency. So watch out.

Important note: "Don't be a simracer". We simracers (yes me too) have been used by decades of information overload and have become control freaks. That was also because older simulations had less dynamic models... once you had your temperatures at a value it would stay there for ever, so simracers tried to achieve perfect values to gain any performance possible. Modern simulators are much much more dynamic. Can't tell exactly how much the others, but in particular for ACC I can say that it is EXTREMELY dynamic. So values and colours will change as you drive. Don't get obsessed about it. As long as you don't see extremes, keep driving. Check the variations on the range of 1, 2 laps, not turn after turn. This doesn't mean that the car are not sensitive to those variations, on the contrary, they are a lot! But you can't do much about it. Concentrate on driving well and the rest will come.

Well, obviously the car will be asymmetrical and that's not good. Most importantly though, if you lost lots of pressure, even if you gain a bit of heat the pressure might still result low and any riding over stepped kerbs can be a very risky situation. So if this happens, you should seriously consider to have a pitstop and change tyres. Prevention is what saves you in such situations. Once you have the problem though, there is no action you can do to "fix" the issue while driving.

 

Nah, it's all @Lord Kunos stuff. I'm just making sure the copy paste works properly
But thanks for the kind words

 

If I'm not mistaken, when it's clear skies and there is nothing changing in the weather for the next minutes, then the forecast won't show up. You can always have a look if you press esc in the pause menu, top right.

 

No it's minutes; usually 10 and 30 - but will scale to realtime for higher time multipliers

 

Temperature indicators are not there yet

 

It indicates wetness, the icon is the same as long as it's dry. The weather forecast can't foresee cloud level.

 

I will for sure and I'm sorry I haven't delivered yet... but it's been, actually is, one of the most intense work moments ever. You saw the changelog... I can assure you there's double of this going on behind the scenes, also on the content.
But I believe we started delivering the goods.
