It's really too early to tell, no snow, no ice, no slush. I had a Prius Plugin Advanced before the Model 3 so I am used to not hearing an engine, just wind and road noise. I think snow tires have always been louder than All Season or 3 Season tires. They aren't obnoxiously loud. I'd guess plus or minus the same as the Michelin 3 season, MXMX. The Prius came with Michelin Energy tires, designed to max mileage but as they wore down (I was driving 500+ miles/wk) they were dangerous in snow. But I got outstanding mileage in the Prius except for winter. There was a table I saw day before yesterday, Tesla Range Table - Teslike.com that showed range for the M3 in various configurations. I don't see anything remotely close to that. I'm probably avg 350-400 wh/mi now. It's partly tires, probably mostly heat. People take heat in ICE cars in winter for granted. One can't do that in a Tesla. That said, I am not so anal to turn the cabin heat off and use mittens and seat warmer. I leave the cabin temp at 70, the rest is what it is. I spoke to several people, one of which was @Mad Hungarian and he concurred with the local tire store the R3s were the best Winter tire period. XIce are in the same neighborhood and appear similarly priced. On the Prius, once I bagged, the Michelin Energy's I put on Nokian WR G4 all season (with snowflake mtn). While there was a dramatic drop in miles per charge from 11-12 to 9 so 25% drop, they were outstanding tires. Nokian doesn't recommend them for the Tesla though. They do have an 18" version so I am guessing they are rated for the weight / tire. I'll see if I can't bookmark this thread / your question and revist it in a month or two with real world Winter tire performance. Or, perhaps April start a new thread on Winter tire performance for M3s.
