It's an R-reg with alloy wheels.
I've spent much of today trying to get a tyre repaired. The vehicle came with locking wheel nuts, which have always been hard on the adapters (the metal keyed thing, not the plastic taker-offer), which start to disintegrate as torque is applied. So we have 3 broken adapters, the wheel still on the car, and a trip to the not very local LR specialist who used a big hammer, a lot of grunt and a huge lever to encourage the worst of them off.
We now no longer have locking wheel nuts and I have a great sense of relief.
What we do have is a one-size wheel brace that fits all the nuts reasonably well, but with some hammering needed on some. The nuts are not all the same. Some are the size of the wheel brace socket, but many have a sort of push on thin "tin" adapter to bring them up to about the correct size.
The spare wheel nuts are different in that the thread goes all the way through to allow the longer studs to go through. They seemed not to have the adapter and so need a different socket. One of the nuts on one front wheel seems to be a spare wheel one, but with a slightly different pressed tin size adapter which unlike all the others seems to be rusting.
What should the wheel nuts be like? Solid or with little leave-on covers? Should the wheel brace need a bit of a hammer-on to get it on to some nuts and not others? Has something gone metric and do I have half of one size, half another?
Googling reveals a fair amount of irritation with Disco2 nuts, not much about Disco 1.
