**Introduction:** Selecting the right wheel size is crucial for both performance and aesthetics. The Wheel Size Calculator assists in determining the overall tire diameter, considering tire width, aspect ratio, and wheel diameter. This ensures a proper fit and maintains the integrity of your vehicle’s performance.

**Formula:** The calculator employs a simple formula to calculate the overall tire diameter: Overall Tire Diameter = (Tire Width * (Aspect Ratio / 100) * 2) + Wheel Diameter. This formula accounts for the tire’s width, aspect ratio, and the wheel’s diameter to provide an accurate representation of the overall tire size.

**How to Use:**

- Enter the Tire Width (in millimeters) in the designated input field.
- Enter the Aspect Ratio (%) in the provided input field.
- Enter the Wheel Diameter (in inches) in the designated input field.
- Click the “Calculate” button to obtain the Overall Tire Diameter.

**Example:** For example, if the tire width is 225 millimeters, the aspect ratio is 50%, and the wheel diameter is 17 inches, the calculator will provide the corresponding overall tire diameter.
