Flotation sizes are written as height × width R wheel in inches, so 32x11.50R15 is 32 in tall and 11.50 in wide by definition. Metric sizes are written in millimetres, so there is no exact twin: these are the closest calculated metric sizes on a 15 in wheel.

These are calculated combinations of standard widths and aspect ratios, not a list of tires that are sold: confirm a tire is made in that size, and that it suits your wheel width.

Regearing
A tire this size is taller than most stock tires, so engine RPM falls at a given speed. See the gear ratio calculator and the regear chart.
Calculated from the size alone. Real tires vary a little by brand and model, and the loaded radius is a bit smaller. Confirm the wheel width range, clearance, load index and speed rating for your vehicle. See how to read a tire size, the load index chart and the speed rating chart.
