Wheels - imperial. Eg "6J 13" would mean 6" wide and a diameter of 13"
Tyres - mix - as it is internationally:
185 50 13:-
185 mm wide, aspect ratio of 50, 13 inches diameter bead to bead
Those measures are from my mini, btw.
Crossply tyres are the only tyres that are all imperial - eg 4.5 x 10.
Those are original fit tyres on the classic mini. Crossply are rare to come
by.

Someone else may have heard the answer but, as I was just told from the
person who asked in the first place, the answer was wheels.
The question I have though is do they refer to wheels in other countries in
inches or just a metric equivalent size. Something tells me its like pipe.
A 12" pipe is still 12" so it fits with older pipe but its called out as
300 mm pipe (in reality its probably not 12"or 300 mm). For our foreign
list members, do you order tires in inches or millimeters?

"In the good old USA we still use something called the "British"
system of measurement, i.e., the mile, the gallon, the bushel, the
inch, the rod, while practically the entire rest of the world has
embraced the elegant simplicity of the metric system.
"As you would expect American car manufacturers used the British
system until globalization infiltrated the marketplace and forced
them to adopt the metric system. Well, nowadays every American
manufacturer uses the metric system almost exclusively. So that
practically every fastener--you know nuts and bolts and whatnot--is
measured in millimeters and even torque specifications are now given
in Newton-meters and not foot-pounds.
"I travel quite a bit and I spend a lot of time in Bucharest,
Romania, where they most likely have never heard of the British
system of measurement. While being chauffeured around town one day
and sitting in in traffic, I noticed something interesting. I noticed
that every car from the lowly Dacia, where none of the body parts
quite fit, to the high-end Mercedes, is using the British system of
measurement. That's right, there's something on all of these cars,
that is not metric. What is it?
"I'm going to give you a hint. Your Toyota or your Volvo or any car
that you drive in the United States might have the same part that's
not metric; that is, it's using the British system of measurement."
