Step 3: Add Rear Gear Ratio

Provide the rear differential gear ratio. This determines how engine power is transferred to the wheels.

Step 4: Select Transmission Gear

Choose the gear you want to analyze (e.g., 1st, 2nd, 3rd, etc.).

Step 5: Click “Calculate”

Press the calculate button to process your inputs.

Step 6: View Results

After a brief calculation, you’ll see:

• Vehicle Speed (in mph)
• Wheel RPM
• Overall Gear Ratio

Step 7: Copy or Share Results

Use the available options to save or share your calculations.

Practical Example

Let’s walk through a real-world scenario:

• Engine RPM: 3000
• Tire Diameter: 26 inches
• Rear Gear Ratio: 3.73
• Gear: 4th Gear (1.00 ratio)

Results:

• Overall Gear Ratio: 3.73
• Wheel RPM: ~804 RPM
• Vehicle Speed: ~61.8 mph

What This Means:

At 3000 RPM in 4th gear, your car will travel approximately 62 mph. This helps you understand cruising speeds and optimize gear selection for efficiency or performance.
