Michelin Symmetry Tires should be considered dry weather tires only. I've had sets on 2 different Mercury Grand Marquis and both had very poor wet traction. Even on this big heavy car, I can break loose the rear wheels easily in wet weather and my experience in wet weather shows the tires have a high tendency to hydroplane. Wear is good, but the wet traction issue I think makes this a poor choice. I've replaced both sets long before tread was worn out.
