I've been wanting to move away from the General Grabber AT tyres I have. Yes, I know they are popular on here, but this is my wife's car and anything tha can't be done on road tyres, she won't be doing!
(Note: I want normal road tyres mostly to confirm that the AT's are the reason my mpg has been bad - 18mpg average including motorway. Before the idiots start harping on about "why worry about mpg" and "if you care about mpg you shouldn't have a discovery" etc - the reason I want to know is to make sure that there isn't something else wrong with the car - if there is, I want to know!).
Well, my hand was forced by a slow puncture in the rear left tyre, which was a nail right next to the sidewall and hence not repairable. I needed to either change the tyres now, or get a replacement AT. In addition, my spare was an MTR - it has about 8mm of tread, but it seems that an MTR is not a good spare the to have. So, I've taken the AT from the rear right and put that on as a spare, and put four road tyres on.
Now, I went with part-worn road tyres. They cost £40 per tyre from my local guy, and have 4-5mm on them. The only thing is, he didn't have a set of four all the same - so I've gone with two pairs. The rears are now on Pirelli Scorpion Zero's, and the fronts are on Michelin Synchrone. Does that matter much on a 4x4? I know that on a "normal" two wheel drive car it would be fine to have a pair on each axel, and I suspect that the same holds true here - does it?
Now, one of my Grabber AT's was punctured and the other is now my spare, I'm left with two AT tyres with 9mm or so of tread. The plan is to use these as winter tyres for a trip to the alps in Janurary. So the same question applies then I guess - do I need to get two new General Grabber AT's for the other axel or will any pair of AT tyres do? And assuming i buy new tyres which will have more tread, which axel should I put the newer ones on - the front or the rear?

I wouldn't mix tyres back to front on a 4x4.
I've no technical reason why really, just don't think it's good practice.
And I certainly wouldn't mix ATs and something else.
The newer tyres should go on the back.
On the other hand I love my AT's and find the mpg is @same as the scorpions I had before.
Don't think I'm a circling vulture or anything, but if you decide to sell the AT's I'd buy them, assuming they are 19's.

They are 255/55/19's, how much would they be worth to you, oh circling vulture? 
See, that's the thing - no technical reason why, just a feeling. I won't be mixing different *types* of tyre (e.g. AT and road), but I think that mixing two different pairs of road tyres seems like it should be OK...

I don't think there's any reason why you cant, as long as both fronts are the same, and both rears the same. Having said that, its not something I would do personally, but if needs must

Bump. I spoke to my guy and he's going to get me Pirelli Scorpion Zero's for the front so that I have a full set of the same tyres. I think I'll be happier this way

Synchrones shouldn't be mixed. Can't tell you why but they shouldn't
