AT2 tyres use 20% MORE fuel
Have had AT2 tyres 255/60/18 on my D3 for 15,000 miles and averaged 27.7 mpg by the on board computer, did brakes and put on summer continental 235/70/17 tyres, over the last week and a long drive to France today now averaging 34.4mpg I always thought I was losing 10% but shocked that the fatter chunkier AT2's have been costing me 20% loss of fuel.
I thought we were through winter hence putting on the Continentals but sods law I am facing treacherous weather tonight and tomorrow, I have used them before in deep snow and they performed well, so let's see
So there you have it, if you want to save a massive 20% on fuel consumption get Continentals on 17" rims, my vehicle is a manual by the way!
So how do you know your brakes weren't dragging and causing the difference?The End

If they really were 255/55/18 that wouldn't help.
Edit... should have gone to specsavers .. scratch that bit
I found about a 2mpg penalty, dropping from 32 on scorpions to 30 on AT2's. However, this was cancelled out by raising the pressures a couple of psi.
On the other hand, the AT2's were cheaper than scorpions and lasted a lot longer. Some you win, some you lose!Long succession of Disco's since 2001...

ANY tyre with an un-road bias tread pattern with have an effect on fuel usage. Your driving a three ton brick get over it .
The trade off for having a "Pretty" tyre that looks hard will be higher usage some people will see lots some wont to many factors
The newer "AT" tyre has a more sympathetic pattern to comply with new regs the plus side is its a little better on economy where as the AT2 has a more traditional ALL TERRAIN look
The Pirelli ATR is a great ALL Terrain Tyre but just does not look "Hard" Function over Form Where as the AT looks in some peoples eyes a more aggressive tyre therefore better as said the trade off is economy if you want this in a D3 (Flawed) the best you can do is fit low rolling resistance tyres strip all extras off and remove all unnecessary weight etc etc etc or buy a boring eurobox like DSL has

Said Eurobox is happily tucked up in it's garage as it won't be quite so boring in the snow.

Tell me about it, I even have a second set of rims for them. I tried to get that past SWMBO but she said "You have a Disco and a Jazz with winters on, you won't need to be out in the BM in the snow". She just doesn't understand the "what if" senario purchasing process.
