I can't offer any answers...because I've never had the problem the OP describes. I use DT rims almost exclusively; my stable currently contains RR1.1, RR465, and whatever the stock rims on a set of DT 1450 Mon Chasserals is called. And I've used Conti GP400S tires exclusively for the past ~4 or 5 years.
To me they're no harder to mount when new than any other tire/rim combo I've tried (and fwiw they're a lot easier to mount than Michelin Pro3 Race tires on those same rims). And once mounted, getting the tires off & back on the rims for roadside flat repair is almost embarassingly easy.
