Summary: THE REVIEW CATEGORIES HERE SHOULD HAVE ONE MORE CHOICE LIKE" NOT AVAILABLE " I DID NOT USE THESE IN THE SNOW AT ALL SO GAVE THEM A 2 STAR FOR THAT. ALL SAID GREAT TIRE ONLY BEEF WITH THEM IS THEY ARE A LITTLE SCARY IN THE CURVES WHEN YOU HIT LOOSE STONE... MORE SO THAN OTHER TIRES I HAVE RAN.
Summary: Only on front two tyres.Rear are existing tyres. Gripped exceptionally well in the summer. Seems to be less traction in icy conditions. The additional thickness of the tyre wall provides great protection for alloys when parking up against kerbs!
