I just put two new GP5000 tubefuls on my road bike. Another nice thing about them - with only a little bit of trickery (leaving the tires out in the sun while I cleaned/lubed chain, washed bike, took wheels off etc.) I was able to get the new tires on by hand and no bead jack needed, though much grunting.
On my touring/gravel bike I run Schwalbe Marathon's and I always have to either pull out the dish soap or the bead jack - those are really tight.
Getting that last bit of bead over the rim while sitting on the shoulder of a highway in the rain is why I do a few extra things to avoid flatting, though older tires are usually easier to get back on.
