AT tyres for Disco4

I’m just getting a black Disco4 with 20mm distance discs and I’m looking for AT-slips in the format 255/55 R20. The normal AllSeason etc. just look too harmless. Because it’s our second car, I don’t care about things like extra consumption or increased rolling noise etc. The M+S with snowflake should be on it already because I don’t really want to have a second set of tires – also wg. the low mileage. On Reifen.com I find only 4 tires (from 3 manufacturers). Does anyone have a recommendation from their own experience?
