You're going to see a lot of conflicting answers here. I know plenty of locals who can't afford snow tires this year/still heading to work like normal. Smart? No. Advisable? No. But it's possible. I think the most important variable is, have you driven in snow before? If you haven't, I wouldnt risk it and use snow tires. These locals I know who have been risking it with summer tires have lived here their whole lives and know how to drive in snow. I'm not saying that makes it less dangerous.... Just more predictable in how to drive/handle numerous skids.

Can you rent a car with snow tires?
