Hi Kerryr,
First off do you have a spare wheel carrier?
If so yes either will fit.
If no then the 265 / 65 R18 will fit under the car only if deflated, it's approx 800mm in diameter.
The 275 / 65 R18 will most probably not fit underneath though, it's approx 815mm in diameter.

I know it has been dne many times, but what is legal in NSW about changes in tyre width and diameter?
~Rich~

Still currently + or - 15mm "Rolling Diameter" only legal max.
Hopefully NSW will follow the other states where up to + 50mm is legal.

Believe it or not Rich NSW have actually adopted the National code as well, which they allow to run in parallel with their own State code, so it is possible to fit up to 50 mm larger tyres providing you get it engineered and then noted on your ego papers at the RTA. Then you must keep the rego papers in the vehicle all the time as proof of the modification in case you get stopped by the Police or RTA.

Actually I thought that was the case for yonks, as long as an engineer certificate was done on the vehicle. Do the other states require this certificate?

In Victoria we do not need to carry certification.
You can suspension lift the car 50mm & fit 50mm dia bigger tyres so 75mm of total lift.

Yep it has, but the mods must not exceed the National code so the RTA told me. Most other States don't require a Engineers cert now like NSW till does. ...:(

From memory the NSW RTA said the national code limited it to 50 mm, whether that was in a suspension lift or tyre size increase or combined they didn't care as long as 50 mm wasn't exceeded.
I'll gladly stand corrected if I 'm wrong.

Hi Kerry,
I have the 265/65/18 BFG's on my L322 RR, only 5000k's to date but very happy, handled conditions recently on the Tanami Rd very well. Ride is also improved over the previous 60 profile GG's I had. I imported direct from Tirepower US at big saving over buying locally.

I thought 65 will take you over the width clearance in Victoria (60 OK). Also - the 265 may rub on the front wheel wheel well when you turn - at least that was what I read somewhere previously on the forum.
Check with boodtl on the forum - he's the one to ask - he does my D3 - Call Tyrepower Camberwell (On burwood rd opp Swinburne Uni)
(I know 265/60s work on my 17" wheels and 260/55/18 work on my 18" hoops)
Cheers

Thanks guys, as my d3 is not my daily drive I think 275s are still a go. Ordered my GOE rods 10 days ago but still not arrived as yet so tyres on next week.

U will love the extra height of the tyres and lift. 
The ONLY thing that is uncool about the MT tyres is the noise. 
Some time next week ill run the lift rods down to std setting and see if there is any rubbing issues. I suspect that they will be ok for Norma road use but for more extreme off road stuff the bigger tyres may jam into the wheel well. 
My mrs took the d3 out in the bush last Friday on the newly squired bighorns 275/65/18 and they apparently went orsome. Got into places the trail bikes couldn't and was blocked in with a felled tree so rather than going back she wet straight over it.  Can't verify how big it was thou but by the sounds of it prob 200mm or so.

Sorry to hijack..
Rich, I have a fully inflated 265/65 R18 under the back of my D3, with full tread. Would they have allowed more room for the D3's that came with the 18's or are the highway compound tyres that much smaller?

Well that is strange, a 285 / 60 R18 would not fit in with either the heat deflector or fully inflated. Its 799mm overall - a 265 /65 R18 is 801.7mm so go figure. :angel:
Only fully deflated with the heat shield removed could I get it to squeeze in, yes pushing and shoving required.

Maybe something to do with the fact that identical tyre sizes from different manufacturers can vary by up to 10mm in overall diameter, even in the same class e.g.  A/T etc, throw in different tread types and they can vary more.
    Or at least they used to when I was into 16" tyres in a big way.

Thanks Lads,
Might be the highway tread configuration. That said I haven't had the spare out yet, I'll try and lower it tonight to see if it is super stuck, and actually put a gauge on it to prove it has the pressure in it, although I have used the internationally recognised method of kicking it.
