Tubes in Tubeless Tyres ??

Tubes are more prone to punctures, and if a bead moves it can pinch a tube. I would personally go with bead locks.

What psi do you want to run? You can safely drop down to 8psi without running a bead off. Careful driving techniques would be necessary though.

Bob I ran a few sets of tubeless tyres with tubes fitted for the same reason, in particular in bog holes. No immediate issues although towards the end of their life I had a couple blow out. BFG's have a small sticker inside the tyre that if not removed can rub a hole in the tube as well. Run good quality heavy tubes & you shouldn't have too many issues. They may run a touch hotter but we don't normally run mud tyres at high speed anyway. They make a cheap set of bead locks.

Thanks for the response fellas.
The tyres are Simex Jungle Trekkers - for winter trips etc.

Last year l ran my 33" MTR's down at 23psi and they were generally ok, but at 16psi, pushed off the bead in the rough stuff. I thought about 2nd air beadlocks but at $250 or so per corner, its too much. Simex tubes are $35 each!
I'm hoping the tubes will hold the bead on and l wont have to worry about losing air.

Another plus. My ladder chains for the MTR's fit the JT's ok too.

I think people go to tubeless when a lot of low pressure operating is called for. If the tyre spins on the wheel a tube will have the valve ripped off any way. Air pressure is air pressure tube or no tube. I cant see how a tube would solve anything. I use tubes because I am too mean to buy new rims for tubeless! As already mentioned there is heating issue and punctures and repairs. tubeless are much easier to plug than tube is to remove and patch at least where the sidewalls are not holed.

A Toyota 70 series that runs split rims has tubes in tubeless tyres standard,

you only have the same problem that we have, that is if you get a puncher the tyre goes flat..

It is OK and for the reason you're doing it is a good enough reason (to me)

Why don't you contact the Nat Importer of the Simex Jungle Trekkers and have a chat to him.

He is a high profile comp person and uses 2nd airs or internal bead lockers (whatever you like to call them)

I have watched him 24/7 on the Outback Challenge where I have a particular 'marshalling' role, and what he doesn't know about keeping beads on the rims at low pressure's is not worth knowing.

His name is Chris Hummer and you find him at Dynamic Tyres in Melbourne.

A tube is not designed to work in a rim meant for tubeless tyres. Damage can occur to the valve stem, as it is designed to work in an elongated hole, and sit central in the rim. The rim also is usually flat across it's inner surface.
The tubeless rim has a contoured surface which is unsuitable for tubes.
I'd only fit a tube to a tyre as a last resort to get me out of strife, ie tyre casings being absolutely buggered.

Wont work for that purpose - in fact the oposite
Iwas running very low pressure on the beach to make a sandy cutting. Unknown to me one of my ytres was running a tube. It spun the tyre a bit wrecking the tube - no worries with the tubless tyres and that was running 5 psi from the cutting at bellingers beach up the top of Mt pasely (I was to slack to reinflate them) and most of the way along poison creek beach until the tube gave up

There's no way in a million years I'd fit tubes, for the reasons above and more.
You'd regret it trust me......

I wouldn't put tubes in tubeless tyres as when i was on the beach at Bell's Point (Near Middle Lagoon, Broome) I had to let my tyres down to 10psi to get out of a bog in the sand, when i drove off the beach the track had a couple of rocks on it but was only about 30m to the camp, pinched the tube and got a flat. Didn't even know there was a tube in it until then as it was the original one on the vehicle when i bought it second hand, pays to have a look! Had it happened on the way down onto the beach it would have been a nightmare to get off the beach!!!!!!
