Same here but with Parcours Chrono. Sealed perfectly first time on rims I taped myself, still hold air really well. From reading the rest of this thread I think I used up a years worth of good luck in a single day

With a DynoPlug in your bag the whole point is that they don’t come off. I would honestly give them a try because they are an incredible tyre.
sure, and I’ve carried DynaPlug since going tubeless but its not a guarantee you won’t need to put a tube in. Luckily when I had a larger slice in my 5K TL it was a hot day and was able to put a tube in without much effort.
Strange experience.
Overall I’ve been more impressed with Specialized tubeless than GP 5000 TL. And one of my S-Works Pro Tubeless lasted ~2500 miles, far longer than all others (Schwalbe Pro One, Zipp Tangente, Hutchinson Sector 28). Plus the Specialized tires have much better road feel and confident grip. I’m going to try the new $50 Turbo Pro, hoping its basically the same as the S-Works Pro Tubeless that was discontinued a year ago.
Can confirm that installing the first time is terrible, but they seem to have loosened up as I’ve been able to remove/reinstall easier roadside after that.
I have the Kool stop tool as well, but carrying it on the road doesn’t work well. Works well at home though.
I’m in the US and going to try and get that Tyrekey. Looks like it would be good for roadside work. My old thumb joints can’t take much more of that hard work getting a tire back on. 
Leaving the tyres to hot sauna for a while helped me a lot fitting the 5000TL’s .
KoolStop Tire jack is excellent, and this stuff helps a lot for mounting
I guess I was lucky. The GP5000TL went on my Farsports rims by hand. You have to do all the tricks.
First I let the tire sit in the sun for 10 minutes.
Second, soap up the bead with a little dish soap and water
Third, start opposite the valve and methodically get it into the center channel. Work all the way to the valve maintaining tension in the center channel.
Once one side is on, install the valve.
Do the same for the next bead.
With heavy work gloves I was able to lift the bead over the rim by hand.

As per KNOWS NOTES - FITTING TUBELESS ROAD TIRES - In The Know Cycling
I found it impossible to mount the Conti 5000 TL on Mavic Kysirium Elite UST wheels. My local bike shop techies who are extremely experienced and professional failed as well. Even though a Continental rep at RideLondon registration in August assured me that they would fit, I have now received a message from Continental stating that the tyre and wheel are incompatible!

Quick Update:
I had two more attempts yesterday, for the last one effectively baking the tire in preparation at over 150C. Mde sure to thoroughly follow all the advice given here, but can’t even get close to getting the second side on.
So thanks for all the stories about other failed attempts, these may allow me to walk away from this personal waterloo with at least a shred of self esteem.
Also if anyone living in Germany would be interested in pair of brand new GT5000 TLs, let me know;)

I just mounted them on a pair of Roval CLX50s. They are HARD! But I managed without tyre levers. I used some soapy water. This did the trick. And lots of technique. I guess having done tubs in the past helped a bit. Difficult to explain but if you look it up online you will find many videos of how people mount tubs. For comparison they are similar to the Conti Competition.
A little talc works too…
well. I no longer have a set of gp5000 to sell!
Left them in the sun, used a decent set of levers, started opposite the valve. they sealed and seated without sealant, so i popped them off the rim a bit, and filled, put back on the rim.
Jobs a good’un. they seated and pumped up first time with a track pump, no compressor or anything.
fantastic.

Nice work. Heating them up definitely helps initially. Once seated for a while they will stretch, as others have mentioned, so it should be much easier in the future.
Get a little valve stem removal tool. Fill 'em up through the valve stem with the valve removed.
Or use a pair of pliers.
You can do that but it mangles the valve stem. It’s nice to have the tool.
True, I’ve got a heap of the plastic Mavic tools but I can always manage to find a pair of pliers quicker!
Intersting to hear about them stretching with use.
I’m tempted for my next set to fit them to some spare alloy wheels well in advance. Wrestling them onto the best wheels was concerning.

Fitting them onto a pair of Kinlin XR22T rims was a major pain the first time. I managed it with two tyre levers and a pair of helping hands to hold the tyre in the rim at one end while I worked on the other.
Once they’ve gone on and come off, it does get easier each time.
