I tried my local Halford/Ripspeed and the guy informed me that if the wheels didn't line up it was impossible to get anything to solve the problem!
Local alloy wheel dealer said the same. Oh the joy of living in the fens!
On the note of the locking bolt, how do you get the wheel to sit straigh on the hub, it must be out to one side to get the locking, straight bolt in? Help. I don't really understand how these little chaps work!
