Are you running thos oressures front and rear? LR recommends 6 psi more in the rear due to the extra weight when loaded I presume.I now have only 19 inch tyres having come from a 2.7 d4 which I ran d694s and d697s in no punctures and belted up and down the oodnadatta and strezelki I r an fronts at about 32 psi and rears at 38 psi if my memory serves me correctly.
Have others had succes with 19 inch tyres or do we sll need to get 18 inch rims as well?
We had 25psi in the front and 30psi in the rear. It is only the rear we are having problems with. We have never had a puncture in the front and only have had problems when we are carrying a full load. We have a tyre monitoring system in the car which we would recommend.
I think they are too low. Whilst you can always be unlucky, if you are having sidewall problems, they are bagging too much. From my experience with them, you need to run them at much higher pressures than high profile tyres.Quote:

Definately think the 18"s are a better option, but you can get away with a lot on the 19"s if you are careful.

Does anyone know about the Hankook Dynapro ATM RF10 ATT 255/55R19.
Just read on another thread they have much thicker side wall. We did the High Country couple of years ago and just had Goodyear Wanglers on and lowered them to 25psi and had no problems at all but we weren't fully loaded. We only have problems when we are fully loaded but next time we will try the higher pressures.
What sort of km are people getting out of their 255/55/19's? Im currently having an argument with my Land Rover dealer for excessive tyre wear and they are blaming it on the tyres. I got ~45000km out of my factory tires before changing.

My D4 HSE came equipped with Continental tyres which were great from a road holding and quiet ride perspective. No doubt they were a 'soft' compound tyre as they only lasted 32,000km! Most of my driving is highway based. No city traffic stuff as I live and work in regional WA. I also infrequently tow a 1.4t camper trailer.
I replaced the Conti's with Coopers Zion's and since that time have carried out a 5 way rotation of the tyres each 10,000km and monitored the wear. I have also kept a good eye on the tyre pressures over this period. My early calculations indicated an expected total life somewhere between the 63k to 70k mark. Currently I have completed 50,000km on the Coopers and have approximately 6mm of tread left on each tyre. This equates to 4mm of usable tread remaining to reach the maximum wear.
My last tyre check was yesterday and I reckon that the tyres seem to be wearing at a faster rate as they get closer to the condemn limit!
Go figure?
My driving type and style has not changed over this time and if anything I have become less adventurous with punting my D4 around courtesy of Mr Plod and those cameras hidden in the brush etc.:angel:
The way things look I think 60k will be good going but in reality 56k to 58k is most likely. That said I have been looking around for replacement tyres. Whilst I have no real complaints re the Coopers I am willing to try something else hence the new Hankook tyres are now in my sights. Some of the posts on this forum give a positive view of these new 19's. Based on the info available to date I reckon I might give them a go. Oh and the price will no doubt help to sway my selection.
I have GG AT's which were fitted from new by ULR. 23 months since new and 75,000 klm's with tread to spare. Good off road and on snow, got stuck in mud in Tassie but the ruts were excessively deep. Downside, they have been annoyingly noisy since around 20,000kms. Dash board buzzes at 90-110 kph which is where I spend 80-90% of my time. Anyone else been bugged by these tyres in respect to their constant whine at speed? As this thread is two years old are the Cooper LTZ still the 'prefered' choice or has a 'better' newcomer come along. I'll soon need to change over.(Family's complaining about the noise!)Quote:

I did the same fitted GG AT's new.
Car is 19 months old & 45,000 km's.
Plenty of tread left.
Good on road, gravel & sand have not really had them in mud.
I have the same problem with a harmonic vibration noise between 90 & 100km/h.
Also thinking about the Cooper LTZ.
Would have liked to get the Goodyear Duratracs which are manufactured specifically for the D4 in 255 55 19 & available through out Africa & Europe.
Have you asked Goodyear Australia if they will bring them in for you? They're likely to be very expensive if they will though, as I discovered when I asked about them in 245/70R17 size. If enough people ask they might decide to stock that size. When I got ready to import the 245/70R17 myself I discovered they now had that size here anyway and quite cheap through Kmart.Quote:

We have just commenced construction on a new warehouse for Goodyear & our project manager is also a keen 4x4er so we are waiting to meet the right person to ask the question.
It would be good if we could gather some numbers to see how many people might be interest in the Duratracs.
