For some new wheels(Hope pro5 fortus35), I was fitting Schwalbe tyres which can be notoriously tight, and bloody tight they were too.
I fought with them for 2 days(couple of hours per) Thumbs were agony and I'd snapped a pedros
Liberal application of soapy washing up liquid/water, I finally got the first tyre on and seated.
I suspect the feeling for similar to a gladiator surviving a match, utterly elated, mentally drained.
Sat, watched a bit of tv, them pumped up the tyre, left it against the settee and settled down for the night, my work done, my challenge triumphed.
Couple of hours later picked up the wheel to find....
I'd only gone and pinched the %$^&@£" innertube.
Off it comes, new tube(no way was i fannying about fixing it after that struggle)
Tyre went on surprisingly easy 2nd time, and paid more attention to where the tube was as the last part of the bead snapped in.
Little bit of air, then fold the tyre to pull it back and release any tube that might have been caught. Was not going to mess it up again. I do this normally, but was going to make damn sure there wasnt going to be a repeat
