Just to clarify, cohenmj is referring to a question I posted almost 2
years ago, in January of 2012. Also overlooked is that a short time
after that post I answered my own question. To repeat that answer:
"The trick was to smear some thick soap solution on/in the hole in the
tire before inserting the spike. I used a something made for easy
mounting of tires on recalcitrant rims, but I am sure that any thick
soap solution would work.I also used a vise grip and a bit of metal tube
that fit around the spike, leaving the base free (sort of like
grabbing a thumbtack by the pointy end). With this it was easy to start
at one side of the base and twist it in."
So no need for the Schwalbe tool if it isn't readily available.
And in response to further new comments from others on Schwalbe studded
tires: I have later not had trouble with missing spikes. My guess is
that the problem comes when braking on steep hills (and there are a lot
of those here in Switzerland). Hard braking might rip out spikes. In any
event, I now have the studded tires on an old bike, bought used very
cheap, just for the times when the roads are icy or slushy. And I now
take care to brake gently, at least when coming to a "routine" stop.
