Why can't I use a tube in a tubeless?

[Nasty]

theres always more girlfriends out there. If you have been living with her for longer than two years you can get half of her stuff, or ALL of her stuff if you fix the tyre dodgey and let her ride. cheaper than the pain shes gonna put you through in the future

edit; oh girl friend not girlfriend. in that case just tell her it was FINE when you left it

Bloody hell ... girlfriend can be so misinterpretted ... I live with Grub darling .... and she on her honeymoon with her husband

figured it out when I re read your post and you said she was on her honeymoon, just a little slow on the uptake. But now you can't play the ignorance card cause she'll read this. silly silly you. You almost got away with it.

Damn (note made ... plan dumb next time)

To answer your original question, the reason you don't put tubes in tubeless tyres (cage included) is that it can trap air pockets between the tube and tyre carcass, which then find their way out eventually and make the tyre drop heaps of pressure, sometimes very suddenly. Tube type tyres don't seal to the rim so can let these pockets of air escape.
Vulcanising is not an option unless it's sidewall damage, don't do it in the tread.
If the tyre can't be patched by a good 'mushroom' patch, don't do it. The 'cut' must be sealed completely, so water cannot enter the structural cords/ steelbelts, where it rots/ rusts them, causing failure.
There's plenty of dodgy ways to fix puntured tyres that shouldn't be fixed, but ask yourself how much your or your freinds life is worth before you explore these methods.

Gee this thread went funny all of a sudden - one minute we're talking of cuts in a tyre and the fact they won't get a WOF with damage to the cords and next thing we're like going to do some girl in or something. Klown what you on?

its what I'm NOT on is the problem. The doctor said I should take my pills but I know better and they taste funny.... whats a suppository?

The story turns out with an interesting end ... the tyre is poked .. .we are going to get a new one .. but will wait till they come home so they can choose .. as they currently have mis matched tyres ... aparently that tyre would not have got its next warrent ... so is not a bad thing that Grub was riding when this happened and not lil'ole'me

sob grizzle...I hit a fuck off big rock on roadworks, tyre stayed inflated, went out the next day..rode 80 or 90kms..low pressure bodgied a repair..had the tyre off looked real hard.....split through all the cords and the movement of the split had eventually pinched the tube....sad part though was the shop i went to thought they might just put in a new tube before carefully inspecting for damage, I don't think they had bad intentions, just lacked the paranoia of an old git like me....end result a loverly michelin with around 2000kms on it is toast.....and no longer in production.....I would NOT even contemplate repair

I was taught that the reason you don't fit tubes to tubeless tyres is that the extra heat caused by friction between the tyre and tube can overheat modern tubless tyres in extreme conditions.

Tubeless tyres have a different internal construction - they are not made for tubes,so there is no need to make a smooth internal finish.The tube can fret on the internal ridges,producing heat I suppose,but ultimatly a puncture.

I fitted tubes into tubeless tyres on the Lada - the Lada wheels are not tubeless rims and don't have a ''safety lip'',so it has to have tubes.I'll have to keep an eye on them,as constant cruising at 220kph will build up a lot of heat....
