Self sealing inner tubes...

I saw it appear in Halfords before proper bike shops back when I used to ride a Raleigh Max Ogre!
In all honesty if I get many punctures it's usually caused by the rim, spokes, tyre pressure or the tyres themselves, once diagnosed I can go for months without getting one.
I hope tubeless stays personally, I'm not jumping on the bandwagon until it's a bit more solid though, the horror stories of people who can't seal the bead to the rim properly and repeatedly burp their air out puts me off a bit. Sealing with soap and things doesn't sound like an exact enough science for me, what if Fairy Lime doesn't work as well as Lemon?0 -

I'd like to go tubless as well but i'll wait until it's mainstream.Norco Sasquatch '07 - Parts?.. break'em and replace'em0

The soap n water really just allows the bead to slide over the rim easier (water works ok, dont need soap), and ensures the bead is free to move into its correct position easier as the tyre inflates. Doesnt seal as such, thats the rubber which does that job.
You can get air burping out if you run low pressures, but just takes a bit of experience to prevent. I had a bit of air burping once when i was running them pretty low, but if you run low pressures just keep an eye on them (like just check them after a short bit of hard riding). If you're burping air, just add a bit more above the pressure you started with.The burping is pretty gradual anyway, its unlikely that the whole tryre would deflate immediately, unless you ran stupidly low pressures. Once you've run tubeless for a bit you know how low they can go before burping will occur. And if you had tubes, instead of burping you'd have pinched the tube, and would end up with a pretty quick flat anyway!!!0 -
You know what, bugger it. I'm still curious about all this, and the best way to find out is first hand, so i shall be trying tubeless tyres soon.0

I'm under the impression that the real advantage of tubeless is the fact that because there is no innertube, you can run the pressures lower in the real muddy stuff which means more grip.
I don't run tubeless, in my road days, I run "tubs" (which is a bit different) and got fed up of carrying a spare tub.Craig Rogers0 -
well go on then, fill us in, what's 'tubs'?0

With respect to the original question; yes, self sealing tubes do work. However, when they rip, the slime goes everywhere and it is not nice. That stuff stinks!
I really want to give the tubeless conversion kits a go. The tubeless compatible wheels don't make much sense to me at the moment. The tyres are too too heavy and the beads have to be silly tight. When they get lighter, then I will give them a shot.
I would like to avoid the problem of pinch flats as well as the extra grip available from lower pressures. The fact that you can lose up to 400g from tubes is a bonus as well!0 -
Tubs where a bit different.
I don't think anyone uses them anymore, but basically, you had special Tub rims in which you actually stuck, using special double sided tape, the Tub to the rim.
Tubs look like tyres, however, they had a inner section sewn into the tyre, this meant you could actually pump the tyre up off the rim.
Sometimes though, you could actually roll the entire tub off the wheel going through a tight corner.Craig Rogers0 -
Tubs sound like fun.. adds a whole new element to it!Norco Sasquatch '07 - Parts?.. break'em and replace'em0
