with 285/60/18 he mentions the need to move the AC lines, but not a mention on the 275/65/18 spec sheet.

Definitely need to move with 275/65/18. And re-model the inner guards with a heat gun to ensure you don't rub holes through them.

Exactly!
I've run both sizes on a D3 not a D4 and I got away without having to move the A/C lines or trim the seam within the rear wheel arches with the 285's. Yes the 285/60 R18's did occasionally rub on the seam and did end up rubbing a hole though the inner guard but the 275/65 R18's are 16mm OA bigger so there is your answer.

ah makes sense.

Just to clarify, is moving the AC lines only for cars with the rear (3rd) zone air-conditioning? or for all cars?

I'm happy with moulding the wheel arches but not crazy about changing the seam/AC lines.

FYI I wrote to prospeedUK who did the car in the video above and they just used lift rods to fit the 275/65/18 but recommended lock stops too. I don't want to be driveng around full time on the 'off road' height via rods so I will have to change my tyre choice

If you do not have rear A/C then it's a quite easy job, remove inner wheel arch linings and bend that seam over with a hammer!
Re mould the linings with a heat gun and refit.

I drive around at standard height and occasionally get a rub when going a bit quick over a speed bump, not enough to worry about though.
On dirt roads I'm normally at +30 with LLAMS.

275/65/18 it is then!

Just noticed you live in Mona Vale, I'm in Cromer!

BTW - buy a LLAMS kit!!!

Hey rich, oh so close, should tee up a 4wd sometime!

Yeah I literally just bought the 3 way rods from GOE, I didn't want any switches visible in the car, by the sounds of it the rods shouldn't take long to change either way and a lot cheaper!

Given our chat above, any tips on where to get this size tyres cheaply nearby?

I found Bob Jane at Brookvale the best, followed by Jax.

There maybe another 4wd W/E planned latter this year for D3,D4 & RRS.

I'm in a club and also a private group to get away with.
