Help with boost alloys-different hole depths

[Sharp]

 Had all my wheels off to spray some cavity wax and noticed my alloys have different depths for the nuts to sit in. Anyone know what's going on?

Corrosion, wrong nuts fitted in the past, wear due to loose nuts?

Just had another look and its only one of them, 4 have a 12mm depth, one has about 2mm. Wonder if the spare wheel is made different and its been swapped over at some point.

I’ve got a set in the shed waiting to go off for painting black , I’ll have a look at those and put a pic up if you want ?

Could it be the washer from the the wheel nut jammed in there.

Here’s a couple of pictures of one of mine ,

Looks like steel wheel nuts could have been fitted to it (which are tapered)

Compomotive used to make an exact replica of that wheel (which is a deep dish, not boost). Often Defenders of 300tdi / early td5 only came with four alloys and a steel spare under a cover so I expect at some point a Compomotive has been purchased to replace a steel spare.

the wheels that the OP has posted a picture off arent boost wheels, they look very much like the "deep Dish" wheels that were offered on discovery ones, the picture that @ianmayco68 has posted is a boost wheel,

id suspect that what @oneandtwo has suggested is a plausable answer, although to me it looks like the wheel has been miss machined at manufacture

Thanks for the replies. A brief google of deep dish and that looks like them. Shows how observant I am but I'd never noticed the difference.
