Bicycle tire sizes

The images you have to have in mind are:

Yes, Sheldon he has separate American and British English versions of pages!!!

For example, Kross bicycle (2017) had a Schwalbe tyre with markings:

42-622 (28 x 1.60, 700x40C)

When inflated, the tires were about 3.5cm wide as measured with a ruler.

And the Mavic A319 rim had markings:

622x19C

In this:

ISO (Etrto): 42-622. So:
- 42 is the inner rim width. The actual inflated tire is going to be even wider.
- 622 is the bead seat diameter. The actual inflated tire is going to be even wider.
imperial: 28 x 1.60
French: 700x40C:
- meaning of the "C" asked at: bicycles.stackexchange.com/questions/16190/what-does-the-c-in-bicycle-tire-size-mean
  - www.sheldonbrown.com/tire-sizing.html#french says A is larger than B which is larger than C, and C means 622 mm
