Timely post as I just had my first flat on TUBELESS tires after only a few rides since going to TL. New bike with new ENVE 7.8 disc tubeless and flat happened at furthest point from home. Would not seal. PITA to get TL tire off the wheel and then convert to a tube setup for the rest of the ride. Just ruins the vibe of the entire ride. Just decided to move back to non-tubeless tires and tubes as I can fix a flat in a couple minutes. I still run TL for my mtn bike though since I run those tires about 15-18psi.
Was it a gp5000? I dread having to put a tube in roadside on those things. Anyhow, I think you have to look at the numbers and decide, I'd guess . . . 50% less chance to get a flat on tubeless vs tubed. 50% of that time the time spent fixing it (simple reflate or reflate+plug) is comparable to tube change or even faster than a tube change. That other 50%, depending on tire/wheel combo might be long or even impossible roadside. If your odds of getting a flat on any given ride are ~5% with tubes, then . . .
Time spent fixing a tubeless setup per ride: .5 x .05 x (.5 x 7min + .5 x 20min) = .34min per ride
Time spent fixing a tubed setup: .05 x 7min = .35min per ride
More or less the same. You can play with the numbers as you see fit. If you really can change the tube in 2min then you are definitely going to be better off with tubes. I'm doubtful on that speed once you include actually getting the tube out, packing up the old one etc., but whatever.
Can't blame it specifically on the tire....it's a combo of the rim/tire setup.
I'm running Reynolds Aero tubeless wheels (2 different sets) and Contil GP5000TL's are super easy on and off....easier than some non-tubeless tires I've used in the past. I had DT Swiss wheels prior, and Schwalbe Pro Ones were a nightmare on those wheels.
I just got a set of Zipp 303S's on a gravel bike, but might just have to see how the 5000TL's mount on them.
