Trivia question-Nuts on Spare wheel carrier

[PhilipA]

I was moving tyres about yesterday as one of my camper trailer tyres had a leak and I had to take it to a tyre place. My furniture in the back meant I carried on the spare wheel carrier.
When I took it off I spun the nuts on with my Ryobi rattle gun and noticed the bottom nut didn't go on as far as the others.
The two spare wheel nuts have a dimple outwards, and I replaced the locking nut with a spare normal wheel nut.
So I had a look down the inside of the nuts and found that the spare wheel nuts with the dimple have a thread cut right to the top, while the wheel nut thread ends about 5MM from the top.
So if you use a wheel nut, it will not tighten onto the spare wheel.

I had an old RRC wheel nut which had no thread( Chinese copy I guess) so I levered the washer off it and pressed it onto the wheel nut to allow it to tighten on to the spare.

I guess the spare studs are longer to allow you to get the nuts started while simultaneously holding the wheel, but what a weird thing for LR to do.

Ah so that's what those nuts with the dome are for, I'll do a bit of rearranging.
Thanks

All this is quite clearly spelt out in the Discovery Manual, on the page titled "Wheel Changing". In my manual (Publication Part No. LRL0650AUS), it is Page 200.

What is the title of this manual? It is not the same as the workshop manuals, however I don't usually read the sections on changing wheels.

Hi Pippin,
The manual I am talking about is the Discovery Owner's Handbook (the one that people usually keep in the glovebox). The book is A5 format (half of an A4 sheet). Publication Part No. given in my previous post on this.

Perhaps the key sentence is:

"Do not use the spare wheel securing nuts in place of the road wheel nuts, or use the road wheel nuts to secure the spare wheel - the nuts are not interchangeable."

Cheers, Andrew

Page 170 in mine LRL 0322AUS. The "Do not use...." was not relevant to me as I had a steel spare. However I have just fitted 8" LR wheels off my spare D2 I use for parts and now have an alloy spare fitted so useful info.
Cheers

On mine only one nut has the outward dimple so I will have to investigate.

Hi Nick,
As it happens, I am looking for 1 or more steel 7J X 16 rims for a Disco 2a: it occurs to me to ask if you have any that you want to sell?
Also, as it happens, I will be coming down to Dunsborough on about the 26th of March!
Could you please PM me if you think we could come to an arrangement?
Andrew

I think the normal number for the spare would be two, the third nut being the security nut that does fit apparently.

I got rid of the security nut after being stranded with a flat and no tool. Had got rid of the ones on the wheels along with the tool, not knowing that there was one on the spare.

This probably explains my dimple nut. I have a bag of nuts and I just grabbed the first one out of the bag.

Page 204 on mine with the same warning, however there is no mention about the outward dimple to distinguish which nuts are which.

The odd thing with my disco is that when I purchased it, it was a one owner, 145,000 clicks with a full service history.

It was bog standard as if it had just left the showroom, so I doubt that the wheel nuts would have been changed.
And as I mentioned above, the only dimple nut on mine would have been the security nut replacement.

It would have been far more prudent for LR to have used a completely different thread for the spare so as the nuts could not be changed.

could you imagine how many cross threaded nuts/studs that would result in:o
they have to cater for the lowest common denominator and thats a LARGE number .

[Fast Freddie]

Call me old fashioned but, in my view, it would have been far more prudent for LR to have used the same system to secure all 5 wheels.
Where does all this unnecessary complexity come from?

England!

X 2 wot Fast Freddy said!

Only the bloody Poms would build cars with so many needless differences. Can anybody name another make of car/4x4 that has different nuts to secure the spare wheel?:confused:

I probably should have a look at that.

have owned the vehicle since 2004!
