[Closed] Tubeless tyre doubts

It does depend on what the punctures are/were as to whether the sealant can deal with them. Thorns and similar *should* be dealt with without you noticing except perhaps for a little loss of air pressure and some sealant being sprayed about. Do you carry anchovies/tyre plugs and the like? The only things that can't easily be dealt with out on the trail are sidewall cuts and dents in the rim.

As to fitting an inner tube into a previously tubeless tyre: you'll need some paper tissues and a pair of pliers. Remove the sealant; scrunch up some tissue and carefully wipe around the inside of the tyre carcase - if there are any thorns, etc. still embedded in the carcase then the tissue will catch and you use the pliers either to pull them out or push them back out. Once all foreign objects have been dealt with then fit the inner tube.

Edit: what were the punctures/problems that meant you took the bike to your LBS? Is it just lack of familiarity with tubeless?

Are they tubeless tyres?

Thanks Whitestone, good advice here.
They are Schwalbe G-One tubeless. Where I live have no room/outside space at the moment to make such a mess and my local bike shop is a couple of hundred metres away. I'd rather help keep them in business.
It's a gravel bike and I was road riding today in rural Ireland, so a little miffed, but I did make it back to the car. I do carry a tube.

Actually there is a Halfords nearby so maybe I'll have a short at repairing it before trying the inner tube option.

What sealant are you using and how much per wheel? Too little can make a surprisingly big difference.

Are the tyres just worn? My friend likes his Schwalbe G-Ones but wore through a set shockingly fast.

Rural roads around me are usually OK apart from pinch flats on loose stones, or Hawthorne thorns.

What actually caused the punctures?

What are the shop actually doing to repair? Probably nothing you can't diy. For small holes, the sort that you expect to seal but sometimes won't, then just stick a standard glue-on (not self-adhesive) inner tube patch on it, exactly like you'd patch a tube. (you hardly need any size of patch, I'm a tightwad so I cut the normal patches down to as small as I think I can, usually about 10mmx20mm)

For a bigger hole, buy some small mushroom plugs. You do need to buy vulcanising goop as well as these use a lot. Both are completely reliable, permanent fixes that will take you less time than it does to take it to the shop.

Also be careful when googling for rubber plugs.

Your use of the word "repair" suggests some substantial damage but then if the damage were that bad then you'd bin the tyre.

In order from least to most severe:

holes from thorns and the like. The sealant should handle these.
larger holes from nails. Some sealants may seal these but higher pressure tyres might mean even the best are defeated in which case a tyre plug will be needed. This can be made permanent by a bit of flexible superglue either trailside or back at home.
short splits and cuts. A couple of tyre plugs might get you home but for a more permanent fix mushroom plugs will do the job.
big splits. A tyre boot plus inner tube will get you home. Once home then you've to decide if the tyre is worth the effort of repair, if the split is close to the bead then it's basically toast. A mixture of sewing, internal patches and glue is what's needed here.

There's a video or two on GMBN about tyre repair that are worth watching.

How much sealant is in your tyres? Leave the bike standing for an hour or two to let the sealant settle then shake the wheels, you should hear the sealant sloshing around. If not add more via the valve.

Once mounted, tubeless really isn't very difficult and you should only really be removing a tyre to replace it, either because it's worn out, irreparably damaged or you fancy trying a different tyre.
