You may have missed the point, this is a second spare to get you out of trouble not when traveling along the Bruce Highway but the CSR or Gibb. When you get to the next town with a tyre changer just swap them over if they can't fix or replace the damaged tyres. I doubt the police in the troupie would really care that there is 9mm difference in offset. They are more likely to ask me why I need so many firearms!


You could always paint it yellow, write 80kmp max. and call it a temporary spare! It would have less impact on vehicle dynamics than a 175/80/19 which is a "LEGAL" option. How logical is that!

I know exactly what it's for, hence the word "hope"(ie)roadhouse

Getting the best option is probably better, you may need to travel quite a long way in remote areas with that emergency spare, 18" tyres are pretty hard to get outside metro areas, even country towns like Tumut, Tumbarumba, Corryong, Mansfield, Bairnsdale are hard to get 18" tyres from to fit a D3/D4, I was lucky and found one at Sale, and one in Myrtleford, he had to drive to Wadonga to get it for us though, very nice of him I thought, that was after 3 days of searching and we were only in Dargo.

Anyway, you have said that the 18" rim from the D3 will fit a 3.0L D4, I have a thread going tiltled compatable parts, can you put that info in the thread, I will be making it a sticky thread so all the info is readily available to D3/D4/RRS owners to view for this exact reason, would be great if you could.

Not near it at the moment but this one.

Thanks rufusking, exactly what the second spare is for, the get you out of the poo quickly instead of frying in the sand fighting tyre irons, I have done that on big beemers and it gets boring fast.

The front requires a 19" (or 18" GOE or RAID) but the rear will take a stock D3 8x18". I've fitted one as proof of concept to use a D3 18" as a second spare. Hell of a lot cheaper than another GOE or RAID. Note though that the D3 is a 53mm offset, same as 19" compared to 44mm for the aftermarket. Of interest the D3 5 spoke dished centre that I have is rated at 940kg compared to 930kg for my D4 original 19"

Will a 17" rim fit on the rear of a 3.0 D4?

Contemplating the possibility of sharing the camper trailer spare.

Afraid not, 18" is the smallest using standard LR rims.

Thanks for the link!

They seem to indicate they're only modifying the front brakes to fit their 17" rims. Are their 17" rims at a special offset?

I'm now assuming that a 3.0 D4 also has larger rear brakes than the 2.7 D4 which restricts fitting a standard 17" rim.

Yes, larger rear brakes as well and 17" don't quite fit.
My 3.0 D4 currently has 17" BMW X5 rims fitted with the brake conversion done well before those in the above link did the same conversion.

If I remember rightly several members who go off road on a regular basis have fitted D3 brakes to their D4's so they can use 17" rims. Apparently it's pretty easy to swap the brakes over and not expensive as there are plenty of wrecked D3's around.

Is it legal? ... I don't believe so.
