I'm on the Uber plan. My Schwalbes popped on with such force that there is NO way in hell they're coming off on the side of the road. I'm on borrowed time. I know I should deal with this in the garage - with a workbench and shop tools - and get the tires off the rims.
Seriously, this is a real issue - tires so %$*#ing tight that roadside repairs are not simply, two levers, a boot and a tube.
Each time this topic comes up, several guys chime in with the "Pinch the tire at the top, pull it into the center/deep section of the rim and work your way down..." advice. Yeah. I know. Been playing with bikes/tires for 45 years. That works on lots of tires... not all.

From a roadside standpoint, I think the only truly universal challenge with TL’s is making sure you’re careful when removing to not spill sealant on your shoes or shorts, that junk is hard to get off!
I don't have any personal experience with the 5k TLs, but that seems to be the nature of that tire, not a difficulty imposed by "ever widening rims" as whatshisname asserts. One club mate, with HEDs, said that they were the tightest tire he'd ever come across, too. He gave up and shelved them; he wants me to give him a hand with mounting them in the spring. Another club mate, with wider tires than the HEDs, had no problems mounting his, though.

I had the pleasure of 3 incidents yesterday on a wet 50 miles. Heard the hiss at about 10 min into the ride but it sealed up nicely and rode another 25ish miles until a gash that was too big allowed all the sealant to empty. Used a dynaplug that didn't seal and then used another one and it eventually worked. Added 2 more oz of sealant and was back on my way for another 5 miles or so but it just didn't hold. Tubed it and made it home. Some cuts are just too big for plugs so I always carry a tube.
As a note of tire review, the tires I was using were an experiment. Vitoria Corsa Speed’s, when I bought them I had read all the reviews about their lack of durability, how fast they were but should be a race day tire. I, of course ignored all said comments and bought them. The moment I received them and saw how light and thin they were I knew they would probably not last long on our roads here. They did feel good while they lasted though! In the end I just didn’t feel like I could trust them anymore, kept them as spares and put a new set of GP5000’s on. I’m about the only full time resident in our valley that uses tubeless so my favorite LBS Owner has a stash for me and sells them to me for $50 each which I greatly appreciate!

I've had two TL leaks that required a tube, both were annoying 15 minutes to flat leaks from internal tape failures. Others already gave tons of tricks for tubing, I've found it no different than the process of replacing a tube on a non TL setup. Break the bead on both sides to get the bead into the center, then pull a side off. It can be harder to break the bead because the sealant can "glue" the bead to the rim but it will eventually break free. In my cases all of my TL setups the tire is not too tight on the wheel.

I had a tape leak at a recent event; didn’t even realized it until I had finished. Luckily, the leak sealed and the pressure remained at around 40psi. I checked the tire and found no punctures, and then realized the tape had failed at one point and the sealant made its way into the rim and out around the valve core. I re-taped both rims and have done a couple of rides since and no issues.
IMO, it’s very important to find a wheel/tire combination that works well together. I recently posted about my failed attempt to convert a set of Ultegra 6800 TLR to tubeless with GP5K TL tires and could never mount them. I wouldn’t want to be stuck out on the road with tires that I couldn’t pop the bead and remove in order to install a tube if needed. All of my tubeless tires are Mavic Yksion Pros, which some people have reported don’t last long, but they meet my needs because they install nicely on Mavic and Ultegra rims and roll very nice.
So far tubeless has been a positive experience for me. I’ve discovered about 3 punctures at home after rides that have sealed properly. I prefer to do repair work at home but it’s nice to know that should something happen that would require me to pop in a tube to get me home I can.

I'm curious of a few things: how big was the puncture (to big for sealant, but small enough to plug?,) and what was the method attempted to get the tire loose? In my experience, even the tightest-fitting tire can still be popped loose and filled with a tube when necessary.
I just got one a couple of weeks ago in the rain when I couldn't see glass on the road and I couldn't tell where the leak was either so bacon wouldn't help. Also you definitely have to practice using bacon. When I got it from the local shop he warned me that it took him about 25 repairs to get the hang of it. I figured it out pretty quick but I'd probably have a problem on the road especially in rain.
