Tracks were just Kold Kutter 3/8 ice studs in them and holy buckets it will dam near pull the front tires. I'm going to go really try them out tomorrow. We have what started out to be about 12-18" of snow and now since warmer temps it has settled to 6-10" but will really be fun with these studded tires. I will let you know how they hold up. So far 1 hard mile on them around the neighborhood and none missing.
