My wire wheels are always a right difficulty to undo. The reason is simple in that my stainless wires are painted black. The paint has got onto the hub & nut cap. Whilst I have cleaned up the hub contact face, the nut is not so easy to do & I have yet to Dremel clean the inside. There always seems to be a more important thing to do. So far a bit of heat & a scaffolding pole to extend the “ breaker “ bar has worked.
