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?
