Yea I got the same story. Apparently they’re an “embargoed item” due to military use. Them damn dangerous assault tyres... dunno if the govt thinks we’re sending them to Isis or some rubbish.

Michelin xzl 255/100r16 tyre

FINALLY have finished with the electrics (only to stick a screw through a plug to short out engine brake :ugh: )

i have run out of time to enquire about a turbo this year but will look into it next.

Question for now is the current Michelin xzl 255/100r16 tyres have tubes in them.... is this so it can run low pressures with out popping a bead?
and what pressures can they run with nothing on board? i did do a search but did not find any answers.

cheers

NO -- tubes in tyres mean that you CAN NOT lower your pressure too much as it will end up screwing the tube round in the tyre and breaking of the valve stem off. They need to be run tubless to go to low pressure.

The pressure to run in them has to be worked out there is no one pressure that suits all. Honestly where to start. Now if someone comes in with something better I would follow what they say.
Me, I'd start out about 40Psi and see what they look like in the side wall (you want the side wall to stand). Drive some (stop) check temp with hand on tyre tread and side wall. Should be roughly same temp and not so you burn your hand. Use a IR temp prob if you have it. Adjust tyre pressure till you find what you can run at. Usually higher pressure - lower temperature, slower speed - lower temperature.

Temperature is the killer of tyres. Now I've been known to be wrong but I believe I remember reading some where that 70°C is destruction temp for a tyre. I like to see mine around +/- 50°C. On a hot day I've seen my Goodrides at 62°C (running on the highway) and then it was time to stop and find some shade and have an afternoon nap.

Any idea why they were running them with tubes being a tubeless tyre?

They're probably split rims, basically all those style are, as they're usually modified oem rims. XZLs are tubeless or TT, doesn't matter either way.
I think I was running them at 45-50 when I had them, truck ~4.5t. 20-22 is a pretty good sand pressure, you can go lower but not sure I'd go much under 16-17, unless it's an emergency.
As Dan said you won't lose a bead but the rim can turn in the tyre ripping off the valve stem.
