the altimax arctics are 1$ more and much more tire.
yes I have owned or driven on firestone winterforce, cooper wintermaster+, general altimax arctics, yokohama ig-20, michelin xice xi2, michelin xice xi3, blizzack ws-70, blizzack ws-50, nokian wrg2 suv, and conti Extreme winter contact.
(coming up blizzack ws-80 this year)
The winterforce do get a better deep snow bite vs a small tread void ice orientated tire such as the xice xi2.
To me deep snow traction is not worrying with any premium winter tire.
as they are all much better than all-seasons, esp oem trash like those Turdenzas you mentioned.
If you like the winterforce at all the general altimax arctics are superior in every way.. and since winterforce studded are no longer value priced.. you should compare unstudded winterforce to studless.
