There are VERY few options out there for E70's using winter run-flat tires...

I'am sorry for the confusion. Every winter tire is a M + S tire. But not every M + S tire is a good winter tire. Because all weather-tires are also M + S labeled and they are not a good choice for severe winter conditions. All weather or all season-tires don't have a good profile for grip in snow and the rubbermix is too hard. In cold conditions you need a soft rubbermix, which stays soft in low temperatures. This is only guaranteed with winter tires.

So Dunlop Grandtrek WT, Pirelli Scorpion Ice + snow or Bridgestone Blizzak are all premium winter tires.

agree with Gary. here in Europe M+S can be printed on any kind of tire like so called all seasons but symbol with montain and snowflakes is allowed on tires with real winter ability only. thats including softer rubber mixture and real snowprofile. i also use Dunlop Granteks M3 which are premium wintertires and good enough even for heavy winterconditions.

as Gry said: xdrive is good for uphill driving, accelerating and cornering ability but in downhill driving and braking you just have a car weighting 2,3 tons and nearly no difference to a 7series.
