Anyone know how well the stock tires work in snow? 2010 Pirellis specifically, but will take feedback from any S197. I'm trying to decide whether or not I need to start saving up for winter tires. I only drive about 550 miles a month and it wouldn't be a daily thing, but need it to work in the snow so I don't get stuck at work at 1am. I already priced new tires and wheels at like 1500 bucks, so I'd definitely like to not spend that. I'm in Indiana so only need to worry about snow 10 times a year or less probably, not for 4-5 months straight. Thanks!
