Yes Hoop, as you say, very similar to the old VW spoked wheels, as well as those used on most cars throughout the 70s. Rain stopped play today so no pictures but imagine a standard flat, steel wheel. Then imagine between all the lug holes there are spokes, so 4 in total... These raise up toward the centre of the wheel to the centre bore, so effectively you have a wheel with the bolt holes where they would normally be on the face of the wheel, but the centre bore is pushed outwards away from the hub... Hope that clears things up a bit for anyone who is having trouble understanding my problem?...
So yeah, the wheels fit fine, they'll need tapered nuts (which I thought the Micra used which is what threw me as to the whole hub/lug centric thing)... So the wheels will go on fine, but as has come up in the thread, usually you would use a spigot ring or something to ensure wheel centre & eliminate wheel wobble, but as my centre hole comes nowhere near the spigot & can not be presumed to be central in either case, I wondered if a spacer ring, sitting snuggly around the spigot, or just around it & a spigot ring added, would help make the wheels more solid & stable, i.e. Wiping out wheel wobble?
The reason I brought up the load bearing on the centre of the wheel is that I read that on lug centric wheels, obviously, the lugs centre the wheel & take the weight of the car & the force of travelling. The same site also informed that with hub centric wheels, the nuts are there solely to hold the wheel to the hub, and it is the centred around the inside edge of the centre hole (makes sense) and it is this part of the wheel that takes the weight of the car & any travelling forces... That was the bit that threw me & got me worrying...
Will get some diagrams up later to try explain what I mean with the taper...
Cheers to everyone for your input so far!
