Configuration

1. Basic Configuration

Edit config.lua to set tire behavior parameters:

2. Cold Tire Temperature

Config.tempTiresCold = 100.0  -- Temperature when no one is in the car

This is the baseline/ambient temperature tires return to when the vehicle is unoccupied.

3. Grip Loss Ranges

The system uses temperature ranges to determine grip levels:

-- 60% Grip Lost (Cold Tires)
Config.Min20 = 20.0   -- Minimum temperature
Config.Max20 = 40.0   -- Maximum temperature

-- 40% Grip Lost (Warming Up)
Config.Min40 = 40.0
Config.Max40 = 60.0

-- 20% Grip Lost (Getting Optimal)
Config.Min60 = 60.0
Config.Max60 = 80.0

-- 0% Grip Lost (Optimal Temperature)
Config.Min80 = 80.0   -- Optimal range starts here

Temperature Zones Explained:

• 20-40°C: Very cold tires, 60% grip reduction

• 40-60°C: Cold tires, 40% grip reduction

• 60-80°C: Warming tires, 20% grip reduction

• 80°C+: Optimal temperature, full grip

4. Vehicle-Specific Configuration

Each F1 car model can have custom tire physics:

Config.CarModels = {
    [GetHashKey("cw2020")] = {
        -- Brake Temperature System
        breakHeatRate = 0.25,           -- How fast brakes heat up (0.0-1.0)
        breakCoolRateMoving = 0.1,      -- Brake cooling while moving
        breakCoolRateStopped = 0.05,    -- Brake cooling while stopped
        breakAccelerationMult = 0.050,  -- Brake pressure multiplier
        tempMinBreaks = 0.08,           -- Minimum brake temp to affect tires
        
        -- Tire Temperature System
        tempTiresMax = 105.0,           -- Maximum tire temperature (°C)
        tempTiresMin = 20.0,            -- Minimum tire temperature (°C)
        BreaksHeat = 0.2,               -- Heat added from braking (°C)
        SteeringHeat = 0.5,             -- Heat added from cornering (°C)
        
        -- Steering/Cornering
        steeringAngle = 20,             -- Minimum steering angle for heating
        minSpeedSteering = 15.0,        -- Minimum speed for corner heating (km/h ÷ 4)
        
        -- Cooling System
        SlowSpeed = 30.0,               -- Speed below which tires cool (km/h ÷ 4)
        TireCoolRateSlow = 0.2,         -- Cooling rate when slow (°C)
    }
}

5. Configuration Parameters Explained

5.1 Brake System Parameters

breakHeatRate (0.0 - 1.0)

• How quickly brake discs heat up during braking

• Higher = faster heating

• Recommended: 0.2 - 0.3

breakCoolRateMoving (0.0 - 1.0)

• Brake cooling rate while vehicle is moving

• Higher = faster cooling (more airflow)

• Recommended: 0.1 - 0.15

breakCoolRateStopped (0.0 - 1.0)

• Brake cooling rate while vehicle is stationary

• Should be lower than moving rate

• Recommended: 0.03 - 0.08

breakAccelerationMult (0.0 - 1.0)

• Multiplier for brake pressure effect

• Affects how much brake force generates heat

• Recommended: 0.04 - 0.06

tempMinBreaks (0.0 - 1.0)

• Brake temperature threshold before affecting tires

• Prevents instant tire heating

• Recommended: 0.05 - 0.1

5.2 Tire Heating Parameters

BreaksHeat (°C per frame)

• Temperature added to tires when brakes are hot

• Applied when brake temp exceeds tempMinBreaks

• Recommended: 0.1 - 0.3

SteeringHeat (°C per frame)

• Temperature added during cornering

• Applied when steering angle and speed conditions met

• Recommended: 0.3 - 0.8

steeringAngle (degrees)

• Minimum steering wheel angle to generate tire heat

• Lower = easier to heat tires in corners

• Recommended: 15 - 25

minSpeedSteering (game units, ~km/h ÷ 4)

• Minimum speed required for cornering to heat tires

• Prevents slow-speed turns from heating

• Value of 15.0 ≈ 60 km/h

• Recommended: 10.0 - 20.0

5.3 Temperature Limits

tempTiresMax (°C)

• Maximum tire temperature

• Tires won't exceed this value

• Recommended: 100 - 110

tempTiresMin (°C)

• Minimum tire temperature (ambient)

• Tires won't go below this value

• Recommended: 15 - 25

Cooling Parameters

SlowSpeed (game units, ~km/h ÷ 4)

• Speed threshold below which tires cool down

• Value of 30.0 ≈ 120 km/h

• Recommended: 25.0 - 35.0

TireCoolRateSlow (°C)

• Amount of cooling when below SlowSpeed

• Applied periodically based on temperature percentage

• Recommended: 0.1 - 0.3
