A great vertical site

Is Amazon the answer to on-line commerce? I don’t think so, especially for deep and complex categories. My latest favorite in this category: The Tire Rack - Your performance experts for tires and wheels. A very good user interface to walk you though what tire to buy. Clean interface. Shipment to local installers that are pre-qualified. This is where I am getting my new Avalanche tires (burning out quick from the Supercharger).
