The SP9000 is a spring/summer/fall tire only. It's compound will not work in the snow. The compound used in summer tires is designed to handle best in warmer weather and is also designed so that there is less tread squirm as the tire heats up. This type of compound hardens significantly in winter weather and loses most of its grip. The Ultra H/P is an all-season compound tire so it will give adequate grip in the snow. It's dry performance(cornering force, breaking, stearing response) is not as good as the Dunlop. The GY does ride well(for a 50 series)and is fairly quiet. The HP is only an H-speed rated (130MPH) and you 850 can exceed the speed capability of this tire. The Dunlop will give comprable performance to the factory Michelin MXM. The GY will not handle as well on dry roads but will give better grip in winter weather. The Tire Rack did a recent test on the Goodyear tire and has done tests on the 9000 in the past.
