Hi there, Just wondering how exactly tyre temps works in AMS2. I've done a few tests with GT3 and F1 cars, but seems impossible to warm up or keep tyres warmed when the track/air is very cold. I've tried to fully close brake ducts, and driving with brake pedal pressed, so that brake discs reached very high temps (like 1000 1200 C°) but the only things that get higher - and this is correct - it's the tyre pressure (above 2 bar). So it seems there is a sort of heat irradiation from brake discs to the tyre, but this doesn't affect the core temp...looks like those temps are just related and very sensibile to air and track temps... In the end, how is possibile to warm up tyres??
The SETA tire model simulates three distinct components of tires with regards to thermodynamics. 1) the “Flash” layer (which is the part of the tire in direct contact with the tarmac), 2) a bulk “Tread” layer (which is the usable rubber sitting betweeb the flash and carcass), and 3) the “Carcass” which is comprised of the internal structure of the tire and sidewalls. The carcass absorbs radiant heat from the brakes and acts as a heat sink. The flash layer generates heat through tire scrub/slip. Since the tread layer sits between these layers, it is influenced by both and is the temperature displayed on the UI/HUD. The two primary ways to increase temps on the tires is to stress the flash layer and increase the radiant heat from the brakes. However, doing so may have negative side effects. The tire thermodynamics for every category are distinct and are balanced for the track and ambient temperatures they are likely to encounter at the time of yeah the series are likely to race. Indeed, as track conditions are limitless and a player can chose to race in the dead of winter, there is a distint possibility that the tires will remain cool/cold no matter what you do.
So it seems the game engine is developped to work towards those expected range values for each and every tire modelled, is there an extensive list somewhere of what temperatures are expected ? Some series run from January to November and at night and day time, that is a huge range of temperature in real world... That would be helpful to know that to avoid wasting hours to get tire in proper range when the engine just won't make it possible ever.
The tires have an optimal temperature range where their grip performance is at their best. Some tires have ranges that are more broad than others. All I an saying is that you may find some track conditions where the tires may reach that range naturally, whereas others the tires may be prone to overheating or have trouble reaching optimal temp. Racing is relative. Its not endeavor where you should expect every tire to be able to reach peak performance no matter the condition. What matters is being able bring the tires closer to peak temp than the competition. whether a series races in the winter or not, is not a affirmation that the tires they use are or should be best suited for “winter only” racing. I think we did a very good job in 1.6 introducing the dynamic and reality of performance sometimes being impacted by track condition and balancing tire performance in those circumstances.
Is there a place where those values are available ? There is very little info in that regards in-game, for example for series where multiple compounds are available, what are the ranges for the soft, medium and hard ? What is the factor that matters most in this game ambient temp or track temp ?
1) nothing official has been published yet, 2) its different for every category, but for now, I dont think its that difficult for players to get a rough approximation of the temp ranges based on UI info, feel and perhaps telemetry. Those that do should have a minor competitive advantage. 4) ambient temps affect brakes, and how the carcass sheds heat. Track temps influence flash/slip based heating. These are modeled. Personally, I believe track temps will dictate the most immediate and observable impact to tire performance. Those that can add or save a few C of tire temp by use of brake ducting, or managing aero to increase or reduce wheel slip, or balance cars mechanically for their driving style should have a slight advantage as well.
The only difference between the tires in TT is that they don’t wear. This means that even in TT, tire heat and pressure settngs apply.
Not really it’s just a semi random date picked from somewhere , I’ve heard it’s possibly a date of an actual race day sometime in some class. So the conditions aren’t always ideal . But there the same for everyone.
Unsure if my game is having issues, but, is it intended for the reading in the setup menu to never reflect any data related to your previous run ? Unless I misunderstand the purpose of those values at the bottom, if so, what are they intended for ?
AFAIK it was intended to show the data from just entering the pits, but there is some legacy bug making it so it doesn't work. (I might be wrong, but I think that is what the issue is)
Yeap, that pit data has never made any sense. Better just check the live telemetry hud during pratice runs. I would imagine this will be overhauled in some way when the tyre set limits are implemented
