Tire Aspect Ratio Solver | Find Aspect Ratio for Target Diameter
Calculate the tire aspect ratio needed to achieve a specific overall tire diameter, given the tire width and rim diameter. Useful for custom wheel and tire setups.
This calculator helps you determine the necessary tire aspect ratio when you know your desired overall tire diameter, the tire width you plan to use, and your rim diameter.
Why is this useful? - **Custom Setups:** Perfect for projects where you're aiming for a specific tire height to achieve a certain look or clearance, especially with aftermarket wheels or non-standard tire widths. - **Maintaining Diameter:** If you change your tire width or rim size but want to keep the overall tire diameter close to stock (to maintain speedometer accuracy and gearing), this tool can help you find the corresponding aspect ratio. - **Understanding Relationships:** It helps visualize how tire width, aspect ratio, and rim diameter interact to determine the final overall height of the tire.
Simply input your target overall diameter, the tire width (in mm), and the rim diameter (in inches), and the calculator will solve for the aspect ratio percentage. You can then look for commercially available tires with an aspect ratio close to the calculated value.
- Enter your desired Target Overall Diameter for the tire in inches.
- Input the Tire Width you plan to use in millimeters.
- Enter the Rim Diameter (wheel size) in inches.
- Click "Calculate Aspect Ratio".
- The result will show the aspect ratio percentage needed to achieve your target diameter.
- The tool will also suggest an approximate full tire size (e.g., Width/AspectRatioR RimDiameter) based on the calculation.
