Universal Tire Size Converter & Analyzer | P-Metric & Flotation
Enter any P-Metric (e.g., 225/45R17) or Flotation (e.g., 33x12.50R15) tire size string to get its full dimensions and an approximate conversion to the other system.
This versatile tool intelligently parses common P-Metric (e.g., 225/45R17) and Flotation (e.g., 33x12.50R15) tire size strings. Once analyzed, it calculates key dimensions like overall diameter, section width, sidewall height, and circumference. It also provides an approximate conversion to the alternative sizing system (P-Metric to Flotation or vice-versa). Perfect for quickly understanding any tire size you encounter and seeing how it might compare to another format. This calculator is your first stop for decoding complex tire markings.
- Enter the full tire size string into the input field.
- Supported P-Metric format: Width(mm)/AspectRatio(%)R<RimDiameter>(in). Example: `225/45R17`.
- Supported Flotation format: OverallDiameter(in)xSectionWidth(in)R<RimDiameter>(in). Example: `33x12.50R15`.
- Click the 'Analyze & Convert Tire' button.
- The results will show the detected tire type, its calculated dimensions, and an approximate conversion to the other sizing system.
