"Please Explain"

At a guess I think you are asking if a 18" (that's inch not foot) D3 rim will fit on the rear of a 3.0 D4. The answer is yes. 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"

A LR 18" rim did not fit the rear (nor the front) of a new 2010 RRS when Sniegy and I tried. However I suspect that the 2010 RRS was fitted with the same callipers as the first 3.0 D4s (eg mine) which originally had alloy callipers that caused the pads to squeal if the brakes were used while reversing, but which were superseded by the 2.7 D3/D4 cast iron callipers soon afterwards. Hence if you have an early 3.0 D4 still with the original alloy callipers then the LR 18" rim wont fit but its not expensive to replace the callipers with cast iron versions.

Just be aware that spacers are illegal across Australia unless accompanied by a certificate of compliance from a certified practicing engineer and they are loathe to provide on as spacers move load centres out and have knock on effects with VSC, TRC, ABS et al

thanks, thats exactly what it is for a second spare
I have 5 GOE ATM

That would make buying a set of GOE wheels slightly cheaper if a cheap D3 18" wheel was available for a spare.Sure there is a 50% chance of having to double swap the flat tyre if it was a front flat.
Will try and download this to the my ECU and start looking for a spare

One could get away with 4 Compomotive rims and 2 LR 18" rims.

You have two legal alternatives;

Buy a tyre changer(ie) tyreplyers or R & R Beadbreaker and a spare carcass

OR

Buy a sixth GOE rim and tyre.

Both around the same price.

The illegal alternatives are;

Grind the calipers so the LR 18 would fit(not sure how much needs to come off)

OR

Replace the larger calipers with the 2.7L calipers

There is one more choice, get a carcass, don't worry about the tyre changer and hope there's a tyre fitter nearby.
