Forget about the MPG. The tyres will wear about waaaay before the MPG increased cost is greater than the cost saving you'll have by fitting AT2s. 2020 SDV6 D5 HSE, Carpathian Grey +

Query to 4site 4X4 produced the answer that the AT2 was only ever a temporary tyre to cover the gap whilst the new tyre was developed. Any commnts or experience of the new Grabber AT yet?
Not true, never was it going to be a "Temporary tyre" untill the new AT tyre arrived.
New EU rules on tyre noise etc, General/Continental are just looking ahead, is this a good move or a bad one, only time will tell.
The new AT is very good and works very well so far, the results will drift in from end users.
As far as the 255/55x19 size we have only good feedback so far, we all like different things in life, your choice as to which tyres you drive on etc.
I honestley think the new AT tyre ticks most boxes so far. 
The sizes they have planed is great news for all 4x4 owners.
Andy.

These were the maths I did when comparing AT2 with scorpions/wranglers etc:
In reality, it's probably only a 3mpg drop, but I worked on a 5mpg difference.
AT2s at 25mpg worst case scenario will cost you £8728 over their 40K mile life (120p/L)
Others at 30mpg will cost you £7274 over 40K (120p/L) - a difference of £1454.
However, Scorpions/Wranglers etc are only good for 20K miles, so you'd need another set of them during that time, and they cost a load more, which completely cancels out the £1454 cost of the increased mpg.
Given that the maths is so crude, and could be out by lots of other factors, it's really not worth worrying about mpg if the tyres last twice as long and cost significantly less...
You start to get closer if you go for a tyre that lasts nearer 40K, but that to me was only the Latitude Tour HP, which was terrible in snow and muddy fields. Again, they cost significantly more, so maybe there's a £1K saving on the Latitudes, but again, the maths is crude, and at nearer 3mpg difference in efficiency, probably closer to a £600 difference... maybe...? 2020 SDV6 D5 HSE, Carpathian Grey +

All I can say is that I've been running the same AT2's on my D2 for 3 years and 45,000 miles and there's plenty left on them-however- I've now got some 19" alloys for it and need a new set of AT2's for them- so any price anyone finds here would be useful! D4 HSE in Stornoway- love it. Jaguar XF, MG TF, D2 ES V8 and 2x TR7s for playing!
Gone- D3- a fortune spent and now a lovely car for it's new owner; D2 G4 replica- Tangiers Orange and survivor of 2 Pot Noodle Challenge's!

Have had AT2s now for 2 weeks so not sure about consumption but agree with what hass been said before, didn't think any of us thought we would get good consumption from a D3. I have found these more grippy than the outgoing Scorpion Zeros but that might be the Zeros losing tread. According to the General Tyre spiel the AT and AT2 have the same grip apart from aquaplaning. What have oither people found comparing grip in the wet etc betwenn AT2s and others?

http://www.tirerack.com/tires/surveyresult...?type=ORAT
The above link is for the tirerack customer survey. It's a big survey, but obviously not very scientific. Still, it's interesting to see how US users rate their tyres.
Because it's US based it compares some tyres that aren't available over here. But it does include the GG AT2, which fairs very well in eighth place, only 2 places below the Pirelli ATR- (sorry couldn't resist )

Interesting that they rate the Scorpion zero so far down. Why do Land Rover consistently put these on their cars if there are better options out there?

I actually really rate Pirelli Zero's on a D3/4 for on road use. I find the steering feel and grip to be superb. Better than the Wranglers HP that I've also used.
They're also not so bad off-road, but not quite good enough for some of the off-roading that I regularly do. Although I must admit I've only nearly got stuck once with Zero's, the TR system sort it all out and really it was my fault as I should have been taken the dsc off and used the low box.
I've also found that tyre performance can really vary according to the type of vehicle. As an example, when the Bridgestone SO2 ceased production I tried the replacement SO3 on my HSV, a rwd 540bhp saloon. I really didn't like them at all, they were no comparison to the superb SO2's. I took the HSV to a track day at Castle Combe so that I could destroy the SO3's prior to getting a set of F1 GDS-3 Goodyears (brilliant).
At the track, I met and chatted with a couple of Sccoby owners who really rated the SO3's, suited their lighter 4wd cars very well.
The huge weight of the D3 seems to suit the Zero's, but the downside is that a set rarely lasts for much more than 18k miles on average.
I'm guessing that Land Rover has to fit a road biased tyre and the D3/4 is incredible off-road on any type of tyre anyway. Pirelli is perceived to be a premium brand (rightly or wrongly) and you average buyer will probably know the name. So if you're shelling out mega £'s on a new D4 you are likely to be happy having Pirelli tyres.
No doubt the main reason is that LR have struck a very favourable deal with Pirelli

Sure you are right particularly the deal bit. I guess when you buy a D3 or 4 you will be impressed with the on road grip for such a big car but it comes from a softer compound with a reduced life expectancy as a result.

Exactly, although most people actually wouldn't be too bothered by a set lasting 18k miles. It's only really the folk here who have previously owned 4X4's fitted with hard compound tyres that complain.
Anyone who previously owned a performance car would be delighted. I've owned many powerful front and rear wheel drive cars and soft compound road tyres don't last long with spirited driving.

After having the AT2's fitted for a few weeks now, I've just done a couple weeks of distance driving and this week has mostly been in the wet (everyday approx. 150 miles).
The AT2's don't come close to the Zero's in the wet on the road (and shouldn't with that tread pattern). The understeer is quite surprising at times, so for anyone new to AT2's just be careful on wet/damp roads. With this in mind, if you're doing mainly road driving and are a more spirited driver in the D3/D4, then more road biased tyres would be better.
For my next set, depending on how much off roading I get in between then and now, I'd be tempted to go the ATR or General AT route.
Darren.

Is this everyones experience with these. If so I am a little  off. I have just fitted 4 AT2s and wanted a mainly road tyre that would be safe for my family for wet and snow! Not happy!

In the snow I believe (no experience as yet, but looking forward to trying out) they are really good and far better than Zero's.
I did say spirited driving, so if you're a fairly normal D3/D4 driver then I don't think you'll notice too much.
I bought them with this slight downside in mind (tread pattern, comprise tyre i.e. All Terrain), so this wasn't a surprise to me, but thought it worth mentioning to people considering buying them.
Darren.
