Often it's soft sidewalled race tyres that'll have the tightest fitting beads, but touring tyres can have the stiffer, less-stretchy beads (I guess because they're built for durability, mileage and not down to a weight).
It's the stiffer sidewall combine with the beads that make it tricky.
Jontea may feel otherwise :) The Gravel King has soft sidewall doesn't it?
Hell YOU may feel otherwise ... although these are quite stiff ...
