Cone spanner sizes..

[potsy]

..what are the usual sizes needed to fettle a front wheel?
Thought I had the ones needed in my toolkit but sadly not, my largest is 16mm and is too small.

Mine are 15, and 17 for the lock nut. But my cone spanners also have 16 and 18 on them, so I guess they vary.

17 for the majority of locknuts I've experienced, but some older wheels use smaller sizes.
