Have a question about the wheels/tires/spokes on my 1974 Commando. The tires on both front and rear are Dunlop K81 4.10 x 19. The front wheel is marked as follows - WM2-19 Trade Dunlop Mark Made in England - and has nipple and spoke diameters of ~ 0.295" and 0.145" respectively. Rim width (measured to the outermost edges) is 2.69". The rear wheel is marked as follows - WM 2.19 Jones 91 0033 Made in England - and has nipple and spoke diameters of ~ 0.245" and 0.125" respectively. Rim width is 2.40". Interested to hear any facts, comments or hearsay on what the correct wheel set-up would be fore and aft, and whether any part of what I have is right or wrong. Thank you.
