If you’re on a budget, used snow tires can be a cheaper alternative. However, make sure the snow tires are lightly used, no more than a year or two old, and don’t have too much wear.
Check the tread depth to make sure the tire has enough life left. A new tire normally has about 11/32 of tread depth. If getting a used tire, aim for something in the 7-10/32 range or more.
Also, make sure the tires aren’t more than a few years old (and definitely no older than 6 years since the manufacture date). Rubber degrades (dry rots) over time, greatly reducing the tires’ dependability and capabilities in adverse weather conditions.
