If I find something like this in a TBC file: Temperatures = (85, 24) What do the 85 and 24 mean? Is 85 optimal temperature? What about 24? a +/- range maybe?
Found this in Clio_PC Temperatures=(85.0, 22.0) // Optimum operating temperature for peak forces (Celsius), starting temperature may be there is other useful information CamberLatLong=(3.30, 0.097, 0.480) // Peak camber angle, lateral gain at peak, longitudinal loss at 90 degrees RollingResistance=1300 // Resistance torque (Nm) per unit deflection (m) on ground PneumaticTrail=5.625e-6 // Pneumatic trail per unit load (m/N), adjusted based on slip HeatBasePeak=(0.15, 0.01) // Base peak slip to compute friction heat, fraction of base to use (0.0=use dynamic peak slip only) Heating=(0.86e-0, 1.42e-3) // Heat caused by (rolling, friction) Transfer=(6.75e-3, 1.90e-3, 3.10e-4) // Heat transfer to (road, static air, moving air) HeatDistrib=(11.0, 96.0) // (Max camber angle, max off-pressure) that affects heat distribution (higher number -> less temperature difference) AirTreadRate=0.0065 // Heat transfer between tread and inside air WearRate=2.000e-7 // Wear rate constant WearGrip1=(0.9800,0.9760,0.9740,0.9720,0.9700,0.9680,0.9660,0.9645) // Grip at 6/13/19/25/31/38/44/50% wear (defaults to 0.980->0.844), grip is 1.0 at 0% wear WearGrip2=(0.9635,0.9630,0.9622,0.9605,0.9540,0.9360,0.8600,0.7750) // Grip at 56/63/69/75/81/88/94/100% wear (defaults to 0.824->0.688), tire bursts at 100% wear Softness=0.65 // Softness is now just for AI strategic use AIGripMult=1.000 // Grip multiplier for AI vehicles (due to tire model simplification) Temperatures=(85.0, 22.0) // Optimum operating temperature for peak forces (Celsius), starting temperature OptimumPressure=(140.0, 0.0180) // Base pressure to remain flat on ground at zero deflection, and multiplier by load to stay flat on ground GripTempPress=(1.95, 0.80, 0.50) // Grip effects of being below temp, above temp, and off-pressure (higher number -> faster grip dropoff)
This all remains pretty much unchanged from rF1, as the old tire model from rF1 is still present, but only used by the AI. So the only thing in the TBC file that affects how the tires are for human drivers is the starting temperature.

The second figure is definitely the starting temperature (°C), has been since rF1. As lemming77 said this is one of the very few parameters in the TBC that still affects 'human' tyres. The optimum temp is only for AI now.
