4×4 Off-Road Calculator Usage Guide

This guide is designed to help you effectively use the 4×4 Off-Road Calculator to determine various performance metrics for your off-road vehicle. Follow the outlined steps to accurately input data and understand the calculated results.

Step 1: Enter Vehicle Information

  1. Vehicle Weight:

    Enter the weight of your vehicle in kilograms in the ‘Vehicle Weight’ field. Ensure the value is between 500 kg and 5000 kg to proceed.

  2. Ground Clearance:

    Input the vehicle’s ground clearance in millimeters. The permissible range for this input is 100 mm to 500 mm.

  3. Tire Size:

    Select the appropriate tire size from the provided dropdown menu. The options range from ‘Standard (31″)’ to ‘Extra Large (37″)’, each corresponding to a specific multiplier:

    • Standard (31″): 1.0
    • Mid-Size (33″): 1.1
    • Large (35″): 1.2
    • Extra Large (37″): 1.3

Step 2: Select Terrain Type

  1. Terrain Type:

    Choose the terrain type you intend to navigate. Options include ‘Sand’, ‘Gravel’, ‘Mud’, and ‘Rocky’, each with a specific performance factor:

    • Sand: 0.8
    • Gravel: 1.0
    • Mud: 1.2
    • Rocky: 1.4

Step 3: Review Calculated Results

  1. Off-Road Capability Score:

    The calculator will compute this score based on your inputs using the formula:

    (Ground Clearance / 100) * Tire Size * (3000 / Vehicle Weight) * 100

    The result reflects the overall balance of weight, clearance, and tire size, noted in points with one decimal.

  2. Terrain Performance Rating:

    This rating is determined by multiplying the Off-Road Capability Score by the selected terrain type factor:

    Off-Road Capability * Terrain Type

    The rating is displayed in points, providing insights into how well your vehicle may perform on the selected terrain.

  3. Recommended Max Speed:

    The calculator provides a maximum recommended speed using the equation:

    40 * (Terrain Performance / 100)

    The result, rounded to the nearest integer, suggests the safe driving speed in km/h.

  4. Trail Difficulty Rating:

    Utilizing the Terrain Performance Rating, the calculator offers a difficulty rating for your chosen trail:

    10 – (Terrain Performance / 20)

    This value ranges between 0 and 10, with a lower score indicating a more challenging trail, rounded to one decimal.

By carefully inputting required data and reviewing these calculated results, you can enhance your off-roading experience and safety.
