I am replacing my Michelin Energy MXV4 tires on my 01' X5. Does anyone have experience with the Michelin Latitude Sport (not touring) tires? I have dedicated snow tires for the winter, so I was looking for more of a summer tire for my 18's. I know the Sports are used on the new Porsche and Audi SUV's but wanted to know if anyone has had them on an X5, and how they were. Thanks.
