Comment on everything actually important is already metric

The wheel is in inches but the tires are in metric!

At least in the United States, tire sizes are a goofy mixture of the two, plus an indirect measurement.
A 205/75R15 tire is 205mm wide bead to bead, fits a 15 inch diameter rim, and is 153.75mm from bead to tread (75% of its width).

Yes, the measurement system is the same everywhere and you need the wheel size somewhere in there, but the size of the tire (if you were to take a slice of its profile) is in metric.

No, like I said, tires are sized in both. The width of the bead is given in millimeters, the diameter of the bead is given in inches, and the height of the sidewall is given as a percentage of the width aka Aspect Ratio.
