Original Tire Width (in mm): Original Aspect Ratio: Original Rim Diameter (in inches): Current Speedometer Reading (in km/h): New Tire Width (in mm): New Aspect Ratio: New Rim Diameter (in inches): Calculate Adjusted Speedometer Reading (in km/h):

Introduction: The Tire Size And Speedometer Calculation tool is a valuable resource for automotive enthusiasts and professionals who wish to adjust their speedometer readings based on changes in tire size. By providing dimensions for both the original and new tires along with the current speedometer reading, this tool calculates the adjusted speedometer reading to ensure accurate speed measurements.

Formula: The calculator utilizes a formula that takes into account the changes in tire dimensions. It factors in the ratio of the new tire width, aspect ratio, and rim diameter to the original values, along with the current speedometer reading, to calculate the adjusted speedometer reading.

How to Use:

1. Enter the dimensions of the original tire – width in millimeters, aspect ratio as a percentage, and rim diameter in inches.
2. Provide the current speedometer reading in kilometers per hour.
3. Enter the dimensions of the new tire similarly.
4. Click the “Calculate” button.
5. The adjusted speedometer reading will be displayed.

Example: Suppose your original tire is 205/60R15, and you want to switch to a tire with dimensions 225/50R17. If your current speedometer reading is 60 km/h, enter these values, click “Calculate,” and the result will indicate the adjusted speedometer reading.
