I've got them on my SRT8 Jeep. Though not quite as good as the OE Goodyear all seasons in snow, I found them adequate. They don't track quite as well, but traction and their ability to get moving was just as good, IMO. As RD said, It can be done...
Width of the tire plays a big factor in how well a vehicle will drive in the snow. Wider is not better.
I'm guessing the whole reason you're looking at the Proxes in the first place is to go a little wider and get some better traction on the street/strip??
That and the fact that you'll likely need an aftermarket set of wheels to get that width (that will get boogered up in the snow and salt) lead me to recommend another set of wheels for those Proxes tires. Get a good set of 18's or 20's and shoe em with the Proxes. Put your stockers back on for the snow. Keep your new set shiny and save that Proxes rubber for the months when snow won't make you waste it. $.02
Seasonal tire swaps are only 32 lugnuts. If you don't want to do it, most tire shops will for a small fee. If you got the new wheels there, many will do it gratis.
