Now which new tyres to get...

I guess just bad luck but has made me not wanting to put Zeon’s back on the car. Yes I too wish I had 18 like the D3 before it had but can afford the $1600.00 dollar rim change for 6 rims.
In the end I have gone with the Duratracs will have them fitted for about 330.00 per tire which is 20 less than I was quoted for maxxis 980

And if you’d dropped your rear pressures to around 30psi you may not have had the problem. 42psi is way too high. I run 28psi in the rear fully loaded on a long trip towing my camper trailer and no problems, including across the Savannah Way from Chillagoe to Borroloola and up the East Arnhem Road to Nhulunbuy.

I have run Cooper ST Maxx and Cooper AT3 on my old Ford Ranger and never a problem. Now I run Maxxis AT980 on my 19” rims and same story. In my view it’s all about pressure and speed in most cases.

good call David, for me it was 24 PSI and low crawling over some shale rocks - other tyres I've used over the years wouldn't have had any troubles admittedly 17"
maybe I'm jumping to conclusions too early and it was just a once off?

Yes you could be right but I have a kaymar plus extra tank and 300 tow ball weight. So 28 psi on 19 inch rims would not be what I would be running at but 34 to 35 psi may have helped the pain in the ass is that the road to to station was only 10km and I had just traveled 350km on the black stuff and at 42psi my tires went up 4psi so I recon I am bang on for the black stuff and from now on will be dropping it back to the dirt.
But this is the first time it has happened in 7 years of traveling on the dirt. So I guess I have been lucky.

42psi at that load on graded roads shouldn’t present a problem.

Absolutely too high on Gibber, but not a normal surface with that weight imposed.

Btw, be wary of that 4 psi “rule”. I’ve tested it under the same loads at different starting pressures and starting from 32psi and then using 2 psi increments for the next 4 days - still only achieved a 4psi increase.

+1 for that. Low profile tyres are especially bad for it.

Its been a few years since I had my D4 but I ran LTZs on it as that was pretty much all that was available at the time. I think they are an inherently poor design for dirt roads. The tread blocks are too thin and too widely spaced. This means its very easy to be unlucky and get a sharp stone penetrate the carcass between the tread blocks - the weakest point.

It was vey important to get the pressures right to achieve a balance between flex in the tread and rigidity in the sidewall. I used to use a 4psi rule on dirt roads. That was drop the pressure by 4psi from highway pressures. If it was particularly bad, such as gibber I would go a bit lower and drop the speed. The numbers may vary for different load situations but that was what worked for me.

Cheers,
Jon

The Pirelli design gets a little noisy once they’re wearing in
The Duratrac will humm almost from new

I have the Pirelli on mine and they are quiet with ~10,000km on them. The ATR+ are a new design and compound (released in 2018) and are quite different to the old design. Have a look at the link below.

Unlikely that many people have worn these down yet but early indications are they will go the distance too.

Pirelli Scorpion AT+ Long Term Review

I have the Hankook 265/60R18 114T Dynapro AT-M RF10 tires. so far they have proven fantastic.

I have used them on some very steep climbs and general off road and rally happy with them.

Braking seems really good and don't have much noise if any on the road. My first set, so can't really advise how many KMs I will get with them though.

Will definitely buy them again.

My Pirelli Scorpion AT+, with 60,000 km on them are very quite.

How worn are they at 60k?

Curious to know given other above reported them (I assume old version) at wearing out at 25,000.

Heck, I’ll never be able to tell anyone here how far I got on a set of rubber.

I’ve never worn a set out [emoji1787]
