Did some off-road driving the weekend on the farm that included a rocky stretch, the D3 handled it extremely well in rock crawl mode. I experienced some wheel spin, but noting serious, and my bother in his Disco 2 managed to keep up. To my horror I noticed extreme damage to all 4 Cooper Discoverer ATR (235/70/R17) with whole chunks of rubber being ripped out. Some of the knobs were complete ripped of, exposing the casing, where others showed tears at the back and front of the knobs. No side wall damage was visible, with only the area in contact with the road showing damage. My brother, driving the exact road with a lot more wheel spin, and having Bridgestone Dueler (D694) on showed no damage at all, not even a nick. I contacted Dunlop regarding this matter and they will look into the matter. Any suggestions to what to buy now, what the best choise (make) and what sizes will fit the 17†rims without catching the wheel arches when off roading? See photo's in my gallery.

I'm suprised 
I have Discoverer ST's and STT's, both of which have been recevied pretty harsh treatment and have survived well. My ST's are currently on 30,000 miles and have been used extensivly off-road with no issues.
Perhaps the ATRs are less resilient. I would recomment the ST's or STT's if you want more off-road bias  (245/70 R17) Duncan

I have put Cooper SST's on the D3 . Found them to be pretty hard wearing on the defender if a bit noisy . BFG now also has a AT and MT that are only slightly larger than standard and seem to fit OK , other than the spare which is a battle . Deondef has gone that route IIRC

The blokes i spoke to in "outback" OZ said
that they dont sell American tyres because they are too hard
for the stony roads, which means the rocks
chip chunks of rubber off the tyre.

Might this be a tyre pressure related issue?
Did some rock work last weekend with BFG,s on and they where fine .

I think BFGs are the exception to the rule.
Mine seemed to chip just as much with low pressures. Pete

I have AT2's and so far have been fine. Std 18 inch OEM size, i.e. 265/60/18. I know that APMOLLER has the same tyre and had bits of rubber ripped off his AT2's on his last trip.

Yup tyre pressures came to mind . If they're too hard you will definitely damage an aggressive tyre

Mine are ATZs, not very aggressive, and when i rang the
importer who sold them to me, he wasnt surprised about the damage.
It sounded like he knew that they would chip on stony roads Pete

Willem,
I run 265/65/17 Dueler At'S on my rig, you'll find that the 65
aspect ratio is with in a few mm of the stock tyre OD. And yes deflate
them when crawling over rocks. D3 bullbar-spots-roof rack with spots-ladder-long range tank-swing out spare wheel carrier- upgraded tow bar-dash console-internal water tank-duel awnings-drawer system & T T.

The popular BFG 265/65 17" is suppose to be widely available by December , although I have heard of a couple of TWT dealers who can get hold of them now.
I went for the 245/75 17" BFG AT which I am very happy with = just have to run them above 2,5 on tar otherwise it drives like a "vomit comet". Only hassle is the spare that is a b  tch to get in and out of well - although when I recently replaced the brand new spare with repaired punctured one - it went in easier.
Do not know what the BFG mud terrains will be like on the D3 -  Erstwhile - D3 S '07. Dual battery system. Upgraded tow hitch. Mantec skid plate. Frontrunner rr. Tmax double headed built in compressor

Hi guys, Im new to this forum. I just bought a set of 265 65 R17 in the ATR. These I bought as a replacement for 235 65 R17 in ATR that were sold to me as in spec. I later discovered they were out of spec and made the change. Before the change, I used them on some bad gravel (several hundred km at speed) and up some nasty rocky tracks and the tyres after a polishing still look as good as new. (almost  ). either you had a faulty tyre or there were pressure problems. But come to think of it, I have never aired down for that particular track as Ive always been in a big hurry! (goes to the water tanks at our lodge and the wife hates to be without water!  ) Of course we'll make it... were in a landy!

The 235 65 R17 combo did let me down though in the sand. with the lower clearance and smaller footprint I battled on the big dunes and was embarrassed in the end by a bunch of yobs in assorted 4x4 and even a freelander   . I hope these new ones alleviate that problem and restore a little pride  next time I venture onto the dunes /deep sand Of course we'll make it... were in a landy!
