They are indeed usually in inches but that’s probably bleeding back to Europe from the US. And most people don’t actually know how much that would be in metric. It’s sometimes listed but no one I know actually uses those numbers. We just know that 65 is bigger than 55, etc. If we want to know if it fits in our living rooms, then we look at the actual size in cm. I also couldn’t think of anything else that’s imperial, at least here in Germany.
Rims are also commonly referred to in inches, at least in germany. But just as with screen sizes, it’s 50/50 with cm, the latter being more useful especially with screens.
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.
Cut it and you’re left with a U shaped slice measured in mm (even if it’s a ratio that’s used for both legs, if you apply a ratio to a measure in mm, the result is something you measure in mm). The tire itself is measured in mm and then the last number is the size of the wheel it’s wrapped around.
That’s the point of view I’m thinking about, the red part is the tire and you only need the first two (metric) numbers to know what it looks like, the wheel size doesn’t influence the width or sidewall height of the rubber.
Also, past a certain point you’re back to imperial measures (35/13.5 x 20 > height x width x wheel) or you might not even have the height/sidewall at all (14.9-42 is 14.9 width for 42" wheels but that’s mostly for tractors.
That’s why they have centimeters (cm). When I buy a TV in Europe the diagonal size is expressed in cm.
People here have a better feeling of what 138cm is than they do for 55’ because they are just more used to it.
Neither is a better measurement, it’s just a matter of what you’re accustomed to. If you were used to banana scale you’d think 8b is easier to understand than 55’.
Yeah TVs/screens for example are typically in inches anywhere I’ve seen. There might also be the metric listed.

It’s a diagonal measurement so it’s literally only useful for comparing screens.
As long as they’re the same ratio 🤪
Yep. Which is probably why no one bothered to use metric.

The wheel is in inches but the tire is 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).

Cut it and the auto shop is going to make you pay for the merchandise you just destroyed.
The diameter of the bead, which is measured in inches, is a critical feature of the goddamn tire.
You really chose the right name.
Goodnight.
It makes sense as an Inch is a good measurement for that. You aren’t going to use mm or meters

’ is feet, " is inches.
Yeah, I get them mixed up all the time. I don’t use them.
TV sizes in Europe are in cm.
