Indeed, plus it's so much easier to remember. Tom, Dick and Harry won't know wheel rim size in metric. Imagine us F1 geeks holding a conversation with the general public and stating the rim size as 330mm. They'll think we're crazy.

Also, imperial measurements are still popular in English daily speech because they're [almost] all single syllable so they roll off the tongue a lot nicer and hence have a bit more impact.Jolle wrote: β27 Feb 2020, 10:14There are three things in our metric world we still do on inches: rims (from a F1 car up to a kids push bike), televisions/computer screens and vinyl records.
Funny thing is with all of them, any other measurement is done in metric.
Just some leftover from an old system.

Thirteen inches is just a nominal size.
These maybe?PlatinumZealot wrote: β27 Feb 2020, 18:54Thirteen inches is just a nominal size.
Like a shoe size. Quite a bit of tolerance is allowed for street cars. For f1 the technical regulations might give you the size in mm.
No, they use 13" wheels... Why wouldn't they?
https://www.ctyres.co.uk/general/metricMetric tyres are quite hard to find the only company still making them are Dunlop and even their stock is often limited. Metric sizes no longer feature on new cars and it just as good as the price of an on off size was very expensive. Today drivers that have metric size wheels are stuck and often find it hard to get stock and if they do manage to find some they are paying over the odds for them. The only alternative is to change the rims to standard size rims.
Most Japanese and European cars use metric sizing for the exhaust: 55mm (2.17"), 60.5mm (2.36"), 70mm (2.75") (outer diameter)
You say that, yet the Goodyear Eagle F1 tyres were (for example, the 1997 fronts) 25.5"x9.5"--13" ... None of this metric business... because USA!godlameroso wrote: β27 Feb 2020, 06:05It's funny because every other measurements regarding wheels and tires uses metric values
I thought it was common knowledge, but most of my friends are of a technical education, and into cars, so they know what an inch is
That's exactly how imperial users feel about metric. A real pain in the ass.the inch is an irritating unit to work with
