I have a 3 yr old BT50 4 x4 with air bags and heavy duty shocks and have managed to get 30,000klm (I think I might have another 5+ in them ) out of my Bridgestone Duelers A/T 245/70R16 111S,I am starting to think what I should replace them with as I have a large slideon weighing around 1000kg,we mainly travel up and down the NSW coast with an occasional off road,I have been told if I have a harder wall tyre it will help with cornering due to my high centre of gravity.Any suggestions would be greatly appreciated as dealers have somewhat confused me.

The originals are pretty useless. I use Dueller AT Light Truck D 694, or there is a later version out the D 697. I have always managed around 80,000 kilometres out of the Light Truck versions. I tow a van, so it's a bit different to your set up but I have never had a problem with these tyres. I guess any of the light truck versions of the various brands would do a similar job.

Best compromise tyre on the market, only tyre that I have come accross that is good in mud/wet tar and still quite.
697 is a bit more aggressivie then 694 but still quite.

Contact Bridgestone, not just a local dealer. Try and get someone who specialises in their 4WD tyres.
I got wonderful advice from a Bridgestone tyre engineer a few years ago who was/is a member of this Forum when I was struggling with conflicting information. I thought he was based in Brisy, but their head office is in Adelaide I understand.
You can get conflicting information on this forum as well from we members.

I have a slide on camper on an old Ford F150 4x2 and have tried a number of different radial LT tyres over the years without total satisfaction. My concerns at the time were similar to yours. Whilst the vehicle size and weight carried by comparison with the BT50 is somewhat different my latest tyres have been a success the tyres I chose for my rig are Nexen Roadian AT11 31x10.50 R15 LT's. I have air shocks/levellers on the rear and also a helper leaf on the rear. The harder side wall and general robustness of the tyre has assisted with cornering roll and side wind stability.Previously the excessive wear on the front tyres was also a problem for me. My ute weights are T1880kg A2880 kg C4600kg and my slide on is a similar weight to yours.
Perhaps the Nexen tyres may be worthy of your consideration also.

The stiffness of the side wall will make bugger all difference to roll stifness in a correctly inflated tyre.

The weight is borne by the air pressure in the tyre.

If you want the tyre to be stiffer....put more pressure in it.

First and above all....weigh the vehicle loaded as it would travel then look up the load V pressure tables for whatever tyre you are running.....this is a starting point lots of people never get to.

That said, some tyres squirm more than others, and that is a more complicated design issue than just sidewall stifness.

Are the tyres you are currently running a propper llight truck tyre ( LT in the tyre designation) or are they a heavy passenger tyre.

The bottom line is there is no cure for a high centre of gravity.
"Ya can'a change the laws of physics Jim"

You have a vehicle that is loaded pretty much to its very maximum and you have a high centre of gravity with it.

The only thing that will significanly help with cornering is slowing down.

That's a fair bit of weight is it an extra cab or single cab? An extra cab would put most of the weight on the rear but you should get more km than that what sort of air pressure are you running I wouldn't be below 55psi in the rear probably closer to 60psi are you rotating tyres about every 10,000km & if it has an lsd that will cause wear but not that much. Maybe you could try some bfg a/t they are a good wearing tyre with a high km range. On another note the heavy duty shocks wouldn't they make for a harsh ride when empty I am looking at putting adjustables on my ute for comfort when empty.

Single cab,after much consultation with "tyre experts" was advised 46 rear 44 front and 50 in air bags (slide on on tray)
Tyres are rotated every 10k
the heavy duty shocks came on at 20k as the originals were useless
The ride is pretty good with slide on on and as you said a little harsh when off but we are mainly driving up and down nsw coast at present

I still think you should have another 10lb in the rear tyres like I said before that's a lot of weight especially when you add up the car and the slide on Lt tyres are usually rated to 65psi. I usually run 50psi in my patrols 285x75 with approx 600 to 700kg of weight in the tray then there's about 160kg for the fuel tank plus everything else just driving around town . I do respect expert opinions but your own experience counts for a lot as well.

Going to Moree and Nth coast NSW next week ,will trial an increase in tyre pressure
