Can tubeless tyres get repaired? My lbs mechanic says NO!!! The only way to go is by using a tube! I like my tubeless tyres, they feel like handling better and go longer without a flat....but when they do....any ideas?

The blanket statement that a Tubeless tire can't be repaired is False! I guess it depends on how big the puncture or tear is! I haven't had anything that wasn't permanently repaired by the sealant. if a puncture is too big for the sealant to keep sealed I guess I would use a patch inside the tire.
I'm putting new tires on all my bikes right now for the season. ( I replace tires every year )

I think may depend upon how the tire is made or how big the hole is. I remember reading claims that due to the way some tubeless tires are made that it is not possible to patch them because the layer that actually seals the tire is in between two layers of rubber and therefore a patch cannot be applied directly to that sealing layer. Air still leaks out even when patched.

yea, it depends on the type of damage, but in genearal any damage that would FUBAR a tubeless tire would do the same to a tubed tire.
You can apply a patch to the inside rubber. I use a sealant, and have never had a tire killing-puncture .

Actually the damage was quite bad (I think)...a steel nail about 5cm lenght! The tyre is Schwalbe's Noby Nic tubeless 2.10. When I took the nail out the hole does not look very bad?!

Pearls of wisdom that apply in many aspects of life: it's not length, but girth that matters.
There are tubless patch kits sold at LBS or on line stores. Also patches with superglue soposely work well.
Try sealer and ride with 1 to 2 ounces in your tire. Change sealant every 2-6mo depending on enviorement.

Yeah, just ordered the patch kit by Weldtite and I will give it a go.... I think that when the lbs mech said that they can't be repaired, he meant that he couldn't be bothered...they charge peanuts to repair punctured tyres and it's not worth the hasstle...
