About This Calculator
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).
