Rear Wheel

[morningside]

With reference to my post on 16th March regarding the rim and tyre size on a 1948 Squirrell : After measuring I find that the current rim is a 19″ x WM2 (Should be WM3) with a 19″ x 3.25 tyre fitted. The wheel has obviously been re-built in the past, the chrome is in poor condition, and I will re-place it. Would a member please confirm that the spoke pattern is correct.

Thanks/Regards/Ian

traditionally the WM 3 rim was for sidecar use and WM2 for solo.
However during the last War WM3 was often the only rim available and worked
on solo machines.. Regards

If the spoke dimpling is correct (ie no obviously incorrect spoke direction) then it’s right for the rim you have. Seventy years is a long time, and wheels may have been rebuilt incorrectly although yours looks right.

Gentlemen,
Many thanks for your response.

With reference to the above and what I posted earlier. My 1948 Scott had a WM3 rear rim and the bike had a sidecar fitted when I bought it in 1954. I also have another post war Shipley Scott rear wheel that has a WM2 rim fitted. So you pays yer money and makes yer choice!
A tyre/rim chart that I have gives the following:-
WM2 Tyre sizes 2.75, 3.00, 3.10, 3.25, 3.50, 3.60
WM3. Tyre sizes 3.00, 3.10, 3.25, 3.50, 3.60, 4.00, 4.10.
