..............This!
The car I'm driving today (in the snow) has four studded snow tires.
Not to try to argue the point...(seems people here can get a bit touchy

but STEEL STUDDED tires and MUD/SNOW and ALL WEATHER and ALL SEASON and YADA YADA YADA TIRES... as well as other variations all can be and are seemingly very different animals.
For example, steel studded tires actually have steel studs embedded into the tread in an attempt to "mimic" the performance of tire chains. To my knowledge other variants do not, (unless installed as an option?) but rather use compounds, tread patterns, sidewall characteristics, etc.. to try and achieve good results in snowy/icy conditions.
Apples to Apples I would be hard pressed to reasonably try to compare any "steel studded" tire with any other tire that does not have the benefit of "steel studs" for snowy and icy conditions, regardless of the vehicle... IMHO
Anyone know differently??
