Bicycle Mechanics - Tubeless punctures.
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
OK. I'm stoopid. First time I ever owned a tubeless tire and I got a flat at lunch time. Inner tubes are easy. A bucket of water will show you where the puncture is.
Not all tubeless punctures are the same. I mean you ain't going to see a yellow post-it note that says, 'Hi I'm the hole your'e looking for.'
What do you do if you can't see where the puncture is? I have not yet taken the tire off the rim, but a quick inspection shows nothing obvious has punctured the tire or is sticking in it. What now? Where do I start?

Have you ever heard of osmosis? Maybe that would explain your puncture.

Just find it!!! AHHHH!!!!!! It might not be a puncture....it could be the valve.....unscrew it, and put some grease or something around the rubber seal thing......if its a fast leak you should be able to FEEL THE AIR Coming out, if its slow then......just figure it out.

I make a solution of dish soap and water and put it on the tire with a sponge. It will bubble up really foamy where the puncture is. Also check the seat between tire and the rim.
These things I shall do. So far, I've done but 10 miles on the bike. I've fallen off once (pox on Mr.Shimano and his PD-M545 pedal) and I have a flat tire.
I think it is time for stabiliser wheels.:D
Spoke to the lbs, and they've given me an inner tube to fit in the tire.
Cars have been using tubeless for years, so I wonder how they look for X-marks-the-spot if there is no immediate obvious point of entry by a foreign object?

Inflate the tire and either stick it in water or rub soap-Water on it. The bubbles will indicate the leak. Tire or valve leak. Thats how they find them in the tubless tires the manywheeled things use.

I`ve worked as a carmechanic for years and yes we did use the water and soap to find the leaks in the tire.
Probably the best and simple solution

HEHEHE i use a solution of glass clearner and some water. I have found that you will see the bubbles show up faster and bigger. But for the most part both will work.
Sorry to hear about your problem :)
