I have speed related ' seat shake' and a general shuddering through vehicle...was present when fitted with 20" Stormers/spigot rings and still present with balanced 18" Hurricanes fitted /no spigot rings. Any ideas as to cause?
No, assuming they are P38 ones.
They were, I have them and they do not have spigot rings, which is why I said "if for P38"Actually mine are Hurricanes and they most definitely DO require spiggott rings. Don't think Hurricanes were officially available for the P38, were they?

Blimey, you learn something new every day. So there are two different hub sizes on Hurricanes? Any idea how to identify the right ones? All 5 of mine seem to require rings. You certainly notice vibration if one is missing (stupid tyre fitters).
