Introduction: Welcome to the Tire Size Speed Calculator, a powerful tool designed to assist you in optimizing your vehicle’s gear ratios for better performance. This calculator allows you to understand the relationship between tire size, RPM, and speed, enabling you to make informed decisions when tuning your vehicle.
Formula: The calculation involves multiplying the product of π (pi), tire diameter, and RPM and then dividing it by 5280. This formula helps determine the vehicle’s speed in miles per hour based on the tire size and RPM.
How to Use:
- Enter the tire diameter in inches.
- Input the engine RPM.
- Click the “Calculate” button to obtain the speed result.
Example: Suppose you have a tire with a diameter of 30 inches, and your engine is running at 2000 RPM. Enter these values, click “Calculate,” and you’ll get the estimated speed based on the tire size and RPM.
