i would imagine running at low pressure with lots of tyre flexing would heat up more than a higher pressure road wheel, Off-roader friends run tubliss at quite low pressure and many have commented on the rim protection that the tubliss inner tube provides in rocky terrain. I dont intend to test that. These friends give their tyres absolute hell, with low pressure and big horsepower being ridden to its limits and they had no issues. One colleague has had multiple tyre changes on the original system and is surprised his "inner" shows no signs of damage. Trail speeds are regularly well in excess of 120kmh plus and machines that pump out MUCH more horsepower than the 40 russian ponies.
Id be hesitant putting this on something that does the high end of 200Kmh but a Ural inst going to be doing much more than 100kmh.
The tubliss literature suggests this system is as light as heavy duty tubes and off roaders are running rim locks as well so in comparison you need to add the weight of the rim locks.
Yes they are marked as off road only, Remember they are American, the country ,that BMW will not sell their Schuberth sourced helmets for fear of legal exposure
i felt more confident using this system after watching how hard these guys treat their off road gear and they have no issues. Proper rim preparation, attention to cleaning and not running the tape out of the centre section, ensure good sealing.
The proof is in the pudding.

Geoff (tracktourer)....G’day mate! your the only one I know of that has run Tubliss on a Ural. Other than WA sand, how did they go on the road? and would it be a fairly easy job on the side of a road to change a tyre (if you happened to shred or stake one) with the tubliss inside it compared to the normal setup? Cheers Wheels.😎

If a tyre is shredded. I think reaching for the spare might be plan B. Inserting a plug as in a tubeless car tyre might be plan A. At the end of it all, I believe a plugged tyre will need an internal patch anyway. I guess the plug will get you to civilisation and a servo. OTOH if the tyre separates from the rim, plan C might be required just to reinflate it. I think the rim itself must be designed for tubeless Marked on the rim with a code. It's an extra lump preventing the tyre from dropping into the centre. Code for rimless is MT or MTH2, A tubed rim code is CP or WM.Dont know what a Ural rim type is?? Anyone??

I had a rapid flat on the pusher of Bobsie’s Tourist!...The valve stem ripped out of the tube and the tyre did all it could to leave the rim. If that wheel had been tubeless there is no way that tyre could have been inflated other than a major explosion to get the beads sealed back against the rim (if at all). It was a half hour job to pop in a new tube and re-inflate. Ural tyre beads come away very easily from the rims!...to easily sometimes! 😎

Low pressure not much help in sand for a 1wd Ural.......as determined by a WA sandy track member.

In Bobsies case as wheels mentioned, the event may have been less serious with Tubliss. The second valve is not only for the inner high pressure mini tube. It is also a rim/tyre lock. This may prevent tyre/tube rotation and loss of the valve assembly. Potentially retaining/reducing the air to a normal puncture. As an addendum to my previous post on tubed vs tubeless rim types. I believe a tubeless tyre bead has a different shape to a tubed tyre bead.

Tubliss interests me!....BUT!...if ya truely want ya ass covered if ya getta flat onya Ural carry a complete spare wheel (making sure it’s not flat!) and know how to put it onya bike!... A spare tube, a coupla rim tapes, some decent tyre levers, WD 40, a decent pump/tyre gauge, valve stem remover and ya only one step offa being truely covered. That last step is strap a spare tyre onya Ural somewhere if ya heading for the long haul (seen it lotsa times). Just Sayin!...Wheels. 😎

That’s bullshit!...it’s got nothing to do with a Ural!...it’s a hard done by 4x4 tyre!...done two hard laps of Aussie in our Troopy and never had anything like that!...seen a bunch though, mostly on those DH’s 4x4’s that go roaring past you that don’t know shit from clay! 😎
