# How to Tune Physics & Tyre Wear in Assetto Corsa

> Adjust tire wear, fuel consumption, and damage multipliers on your Assetto Corsa server to customize simulation rules for your racing league.

## Customizing the Simulation Environment

The mechanical behavior of vehicles on your Assetto Corsa server is governed by a set of physics multipliers. Whether you are hosting a hyper-realistic endurance league that requires strategic pit stops or a casual drifting session with infinite tires and fuel, understanding how to manipulate these variables is essential. These settings are defined within your core configuration files and apply globally to every driver on the circuit.

## Core Physics Parameters

To adjust the simulation intensity, you must modify the following variables located within your `server_cfg.ini` file.

<Tabs>
  <Tab title="Tire Degradation">
    **TYRE\_WEAR\_RATE:** Controls the speed at which rubber is consumed during driving.

    * **`100`:** Standard realistic wear.
    * **`0`:** Disables wear entirely, providing infinite tire life (ideal for practice or drift sessions).
  </Tab>

  <Tab title="Fuel Consumption">
    **FUEL\_RATE:** Determines the rate of fuel depletion during a session.

    * **`100`:** Standard consumption based on vehicle engine maps.
    * **`0`:** Disables fuel usage, allowing for uninterrupted long-distance driving.
  </Tab>

  <Tab title="Mechanical Damage">
    **DAMAGE\_MULTIPLIER:** Scales the impact of collisions on vehicle performance.

    * **`100`:** Full realism; significant collisions will result in permanent suspension or engine failure.
    * **`0`:** Disables damage, making all vehicles indestructible.
  </Tab>
</Tabs>

## Community Profile Recommendations

Depending on your server's theme, we recommend the following baseline configurations.

<AccordionGroup>
  <Accordion title="Professional League Racing">
    Maintain all values at **100**. This ensures a level playing field where tactical decisions regarding tire management and fuel maps are a core part of the competition.
  </Accordion>

  <Accordion title="Casual Drift & Freeroam">
    Set **Wear** and **Fuel** to **0**. We suggest a **Damage** value of **10-20**. This setup allows for continuous uptime without requiring pit stops, while still providing a minor penalty for major accidents to encourage safe driving.
  </Accordion>
</AccordionGroup>

<Tip>
  ### Applying Changes

  Physics multipliers are read by the server engine during the initialization phase. You must **Restart** your server via the Game Panel for any modifications to the `server_cfg.ini` file to take effect.
