Re: Additional improvements

Tyre changes:

• Slightly bigger grip gap between tyre compounds (1.6 between C5-C4-C3-C2 and 1.0-1.2% C2-C1-C0) very small difference but just a bit more accurate by what the gaps are often said to be + balancing out different tyre heating!
• Less grip loss with wear for the tyres, while it may be realistic the player and AI don’t manage their tyres/temperatures in any fashion near real life which makes the tyre wear/grip loss more severe so something like 10-15% less grip loss would be more suited to the game while still providing good realism and yet not too drastically reducing the grip in short race distances!
• Ability to set tyre pressure for each compound individually
  • A must for realistic tyre temps!
• Make the surface temp behavior more realistic, most of it comes from a big increase in “SpecificHeatCapacity” and then minor additional changes for finetuning
  • This would in turn cause the tyres to overheat (depending on the compound, pressure and track temps) or be too cold but the latter can be counteracted with higher pressure by the player and the first is also no problem with the lower grip drop off now!
  • As the brake cooling is always the same it will get rather different results to real life on some tracks for example at Jeddah where the tyres cool out quickly on the straights but the brakes are also cooling down a lot as they have the same cooling as in Monaco (which needs it much more) but IMO going deeper on brake temps should wait another year as it takes quite a bit more
• For more realistic tyre temps per track add a minimum tyre pressure for each track
  • Place them relative to where they are IRL between lowest pressure (usually Monaco) and highest pressure (usually Silverstone) so Monaco would get 22/20psi and Silverstone would get 25/23psi (IRL Monaco was 21psi and Silverstone 26.5 psi)
    • Canada was at 22psi this year so something like ~22.5/20.5psi ingame would be the relative placement
    • Austria was at 23psi so ~23.1/21.1psi ingame
    • Belgium was at 25psi so ~24.2/22.2psi ingame
  • Ideally you would add ~1.5 additional psi worth of pressure - for the high minimum pressure circuits so we have some headroom to increase for low track temps or rain
  • Intermediates usually have 0.5-1.5psi more minimum pressure than slicks and Wets 2-3psi less but I don’t think this depth is necessary!
  • This would also help balancing the AI and their tyre pressures used vs. what the player does, otherwise there might be a big difference in temps solely due to the pressure used
  • You could also just use the exact pressures from real life but would need to change a lot more so the proportions of heating etc. are still right. Also I think it’s easier to just base the game pressures off of the front tyre pressures IRL as the balance between front and rear pressures and therefore temps/grip shift quite often between 1.5 and 3.5 psi, would be more realistic but probably a lot more work for the AI
  • This would change the tyre wear for some tracks slightly but might be worth a little rework of the default expected tyre wear
• Only 1 exact carcass temperature will reward perfect grip!
  • C5 = 90°; C4 = 95°; C3 = 100°; C2 = 105°; C1 = 110°; C0 = 115°; Inters = 80°; Wets = 70°
  • The drop off should be similar to below but for casuals you could make the rear tyres have a bit less grip drop off when they are not at perfect temp so people don’t complain about bad traction

• Surface temps for all tyres should range from 25-30° up to 150° unlike the current game where dry tyres cant have lower surface temps than ~53° which is necessary though for more realistic temp behaviour
• I could provide a whole table for the tyres that would work and what pressure should be the minimum for each track..
• For the tyre strategy the grip difference between compounds goes up or down depending on the track temps - for simulations only, the real difference will be made by tyres overheating or not heating up enough. A appropriate table could be done for every track for higher accuracy as each track and individual minimum tyre pressure would heat the tyres differently
• So the cooler the tyres the better the expected race performance of softer tyres/the worse the expected performance of harder tyres and vice versa for high temps

• The chosen tyre allocation for AI depending on the track temps forecast should be like
  • 10°-25° soft allocation
  • 26°-49° balanced allocation
  • 50°-65° hard allocation
• This would give a lot more depth to the tyres but its probably too much for the very next iteration of the game considering that there is A LOT of work to be done to make the game worthy of the high price tag again!
