This is a set of four Nokian Hakkapeliitta R 235/45Rx17 winter tires (M+S and Snowflake designation). Originally purchased from KalTire, mounted & balanced on Audi OEM 17" wheels with centre caps. Wheels are genuine Audi 7.5"x17" alloys on 5 x112 bolt circle with 57.1 mm centre bore, ET45 (standard Audi A4 B7 set up) - may fit other models. Nokian Hakkas feature black ice siping and are one of the best rated winter tires available. Very limited use with only 2500 kms. on tires from new. Have now purchased another vehicle and these wheels/tires do not fit. All in excellent condition and ready to go.
