Not a tight fit. Aching! where was the blood?
In general new folding tyres are harder to put on than those with a
steel bead. Fortunately if you have offered insincere prayers to the
puncture fairy you will find the tyre easier to fit as it has been
stretched a bit by the original fitting and riding.
Other factors that make tyre hard to fit. Too much air in the inner
tube (you want some to avoid trapping the tube). Thick or badly
fitted rim tape (a single layer of the correct width velox is all that
is required). An overlarge inner tube (Continentals one size fits
all, tube free with their 28mm tyres is a very bad joke). Badly
trimmed bead (Hutchinson are guilty of this)
I can not offer much practical advise. My changes over the past few
years been fairly easy. (I have given up on the free Conti tubes,
pushes on easily with the conti tube or third party ones).
In the bad old days I used to partially fit the tyre then grab it
three and nine o'clock and push down. In theory this pulled the tyre
tight on the fitted side so that the unfitted side had a fractionally
more tyre to play with.
