If i may....
there's a technique in fitting tight tyres that most people can't quite believe actually works until they've seen it.
(I think this is because tyre levers are so ubiquitous that you assume "they must be there for a reason" and start
levering away.)
It involves gripping the tyre with both hands and kind of rolling it over the rim where the tyre is still loose enough
and gradually up towards the finish where it is tight.
You should not need a tyre lever for all but the tightest meyabitch of a tyre.
Conti 4000s are very tight - especially the skinny 20mm ones (try working up to the valve so that the valve stops the
inner tube from being pulled down against the rim for that last tricky bit)
That said i've run a pair daily for about 6 months anywhere from 90-120 psi and not a single puncture so far.
