I went with Toyo Proxies 4 Plus tires and bagged a spare with a baby floor jack in the trunk. Not many XL load rated all-season performance tires on the market, and I loved the way the Toyo performed on my Audi RS4.
Most of the RFT options available are touring tires with very stiff sidewalls. Your choice really depends on your driving style, ride comfort, and weather conditions you expect to face in your car. If you have a snow car or a winter wheel set, then by all means go with the Michelin PSS, but if you set it and forget it then consider the Toyos.
