About RPM and Wheel Speed

RPM (Revolutions Per Minute) measures how fast the engine or motor is spinning.

Wheel speed depends on several factors including gear ratios and tire size.

• Higher gear ratios reduce wheel speed but increase torque
• Larger tires reduce overall speed at the same RPM
• This calculator assumes direct drive through transmission and differential

This tool helps you estimate top speed, gearing effects, or tuning changes for cars, motorcycles, or RC vehicles.
