I have heard this criticism of some other cheap, studded tires but Continental doesn't make cheap tires. Have you used these tires and experienced a rapid wear? Personally I can't speak for their durability as I've only had them a couple of months and put maybe 200km on them so far, but I haven't lost any studs and I don't see any wear at all yet.
I'd certainly believe carbide wears better, but the Contis have hardened steel studs. I'd be interested in hearing others' experiences with these tires.
