Consumer Reports most recent tire test would seem to indicate that that tire most likely is a Michelin. According to autoblog, which has posted the Consumer Reports press release,
The Michelin HydroEdge was the top model among S- and T-rated all-season tires, the Michelin Primacy MXV4 scored top marks for H-rated tires and Michelin Pilot Exalto A/S won in the V-rated all-season radial category. The Michelin X-Ice XI 2 topped CR's ratings for winter tires for passenger cars.
While Michelin won big, the top-notch radials were also among the highest priced in many categories. Other stand-out performers costing less include the Hankook Optimo H727, Nokian WR G2, and Dunlop Signature in the all season H and V speed rating category. The General Altimax Arctic took second place for winter tires.
