Why is a tire’s dimension described using inches, millimeters and percentage? Is it to annoy ppl or to make the believers of the imperial and metric system happy, all at once?

It’s not only car tyres. 20″ Bicycle tyres? Actually 16″, they’ve decided to do the outer rolling diameter for measurements there…but on moto tyres? It’s rim diameter like on your car.
You could make an argument for why we use inches for the diameter but while we’re measuring tyre width it’s millimeters but when it’s a rim width? Yup back to inches. Put that 265mm tyre on that 9.5″ wide rim
Tyre manufacturers are sadists, you’d probably need another ELI5 to explain it.
