Hi Landoman (and others)
Just got back today after 7,000km around central Australia. Ran the tyres at 38 psi cold on the bitumen as this took some of the bumpiness out of the trip (outback bitumen not as smooth as those on the east coast). Ran the tyres at 28psi cold (32psi hot) on the Oodnadatta track and they were excellent with no problems whatsoever. Car was fully loaded with 4 occupants (not towing) and I generally didn't exceed 80km per hr. On another part of the trip through The Flinders Ranges when talking to the tyre power bloke in passing at Hawker, he said he rarely sees side wall damage but mainly tred, indicating people generally run the psi too high. He did however say he has repaired several rims from people going too fast over cattle grates when they have low psi.
Hope this helps
Michael

I've just order my 3 set of Zeno LTZ in 285/50*20 for my D4. Excellent alround tyre. My first set did 50,000km and still had plenty of life but decided to put a fresh set on for a snow trip. My second set also did 50,000km including a30,000km around Aus trip, heavily loaded and towing 3 ton van.

The D4 was a superb tow/touring vehicle and was faultless except for needing a new battery in Darwin. No punctures or flats for the whole trip And we did plenty of offroad/ outback tracks, including gib river, mitchel platue, cape leveque, bungles, Fraser Island, and plenty of beach driving. I used exact same pressure I would have if running conventional 4x4 tyres ie 25-28 psi on corrugated roads and down to 15psi on soft sand. Whilst i think you need to be more watch for sharp square edged rocks etc you can through car around a lot more in the turns without having to worry about excessive tyre roll or rolling tyre of the bead when running low pressures. This set was pretty worn out after a hard 50,000 Kim's. On road they are great but can be susepable to aqua planning in severe wet conditions, partly a function of tyre pattern and partly due to extra width of the 285,s. could recomended them more highly. You will experience slight rubbing in the front wheel wells with this size but it only touches the main chasis frame at full lock but doesn't need any action.

I know we have spoken before but do they fit in the spare wheel well.

Yes, I forked out for 5 tyres and no issues with the spare fitting correctly underneath.

Tyres on, they look terrific!!ImageUploadedByTapatalk1368154009.690395.jpgImageUploadedByTapatalk1368154024.544156.jpgImageUploadedByTapatalk1368154045.313805.jpg

Put them next to the standard tyres - BIG DIFFERENCE!

Huge difference! Can't wait to give em a go. They balanced up real nice as well barely any weights! Impressed

Sounds silly, but my fuel consumption with the Zeon, which were just fitted, seems to have improved.

Does anyone know if the outer diameter of the Zeon is the same as the Wranglers, or are wider?

Do noticed increased noise (just; the sound proofing (I think using 3M soundproofing batts) in the D4 is excellent), but so far in Monsoon season in Sydney, grip seems to be fine.
