I'm gunna have to agree with Alpine on this one. I've done about 55 - 60 in the snow out here; driving and turning are two different things. Knowing where Alpine drives, there ain't a lot of turns to be made, there are huge sections of 285 that are dead on straight. Even that speed doesn't pose too much risk when there is nothing but open fields on each side - no trees, no other cars, nothing to wrech yourself on. Sliding off a road isn't what kills you, it is the tree you run into.

Snow is very different in different temps, and different packs. Unpacked cold snow has a lot of traction, packed warm snow is slick, cold snow on warm roads = bad. Nothing is good on ice, except maybe those big trucks up in the Yukon hauling over rivers and lakes cause it is the only time of year they can (going about normal highway speeds btw).

Tires and wheelbase play a big factor. My daily driver is a Wrangler Unlimited. The other day coming to work I was putting along at 30ish on a cold snow packed road, when a short wheelbase Wrangler spun out in front of me. Nearly the same rig (different wheelbase), same tires, same speed, different results.

Sorry to continue the hijack, but Alpine's right, imo.
