Introduction: Selecting the right tire size is crucial for optimizing the performance of your vehicle. The Max Tire Size Calculator assists automotive enthusiasts and professionals in finding the maximum tire size based on essential factors such as gear ratio, vehicle speed, and engine RPM.
Formula: The calculator employs the formula: Max Tire Size = (Speed * 336) / (Gear Ratio * RPM). It calculates the maximum tire size by considering the vehicle speed, gear ratio, and engine RPM.
How to Use:
- Enter the gear ratio of your vehicle.
- Input the vehicle speed in miles per hour (mph).
- Specify the engine RPM.
- Click the “Calculate” button to obtain the maximum tire size.
Example: For instance, if your vehicle has a gear ratio of 3.73, a speed of 60 mph, and an engine RPM of 2500, the calculator will determine that the maximum tire size is approximately 30.23 inches.
