Gonna put some winter tires on my 300e stock rims. I'm looking for a dependable winter tire, but dont know exactly how to judge a good one since Ive never used them before. Is the difference in traction really noticeable? I'm going to run the 195/65/15 size and am looking for any suggestions/experiences with different brands of winter tires. I will do mostly local driving around the campus ( no more than a mile each way) but the snow can get packed here in the midwest. Thanks.
