R100 GS Tubed tubeless ?

[Tetley]

just had a puncture repaired on the front of the 100 GS. Found someone who could do a tubeless repair only to find I had a tubed tyre fitted with NO inner tube and a tubeless valve. Returned home and checked the rear and that's marked as tubed, so let's see what's in there tomorrow. Tyre guy reckons this is v dangerous. I can't believe it works. I've done about 1000 miles on these tyres.......

They should be tubeless. I'd be going back to whoever fitted the tyres VERY PISSED OFF. At the very least he has made a mistake. I can't imagine someone doing it on purpose. If they tell you that it doesn't matter get even more pissed off and threaten them trading standards and any other official body you can think of. They owe you 2 proper tyres. JJH

The tyres were on when I bought the bike, so no come back on the fitter. I have fitted a new tubeless one on the front, and will be doing the same on the rear tomorrow.
Still can't believe that you can fit a tubed tyre without a tube!

I'm only guessing, but for what it's worth I reckon a tubeless tyre must be a bit stronger than a tubed version in order to withstand the forces required to seat it on the rim. I'd guess that a tubed version may be more of a risk to either getting stressed and damaged on the rim or at risk of coming off the rim? Some fitter assumed it would be tubed type bike rim as most are that way and couldn't be bothered to rectify his mistake when he got the wheel to hand bit fitted it anyway to save him or herself the hassle.

Tubed tyres are simply porous and are not air tight. I know this from my own experience. JJH

You could have saved a bit cash by just fitting tubes - it will me a big disappointment if you fit new tubeless and find they dont hold air.

I couldn't find a tire that did and ended up with tubes anyway.
I have picked up a couple of nails in tubed tires recently , and the tubed tires have held air just as well as a tubeless would in the same circumstances, so I cant se a lot of gain in using tubeless anyway.

There is a massive gain in tubeless when it comes to mending the puncture and getting home. JJH

why would a Tubed tyre come of the rim, or get stressed for that matter, the only difference is the acceptable level of porosity, tubeless rims have a raised bead to stop the tyre from coming off the rim,

if the tyre was not going down, then I wold have lived with it!

Was only guessing and obviously wrong from what I see in subsequent posts.
