YOU GET WHAT YOU PAY FOR!!!!!!!!!!!!! Don't scrimp on quality.
In this case, I think a tire that is rated for speeds "above" 149 mph is overkill in a country with a maximum speed limit of 75 mph. Yes the XF is indeed a fine car... but an ultra high performance race car it's not. Most ownwer's in the USA will never see sustained speeds of 100 mph and would be fine with anyone of the other name brand tires.
If you feel it's that important to put Michelin's on the car spending just over $2k for tires... go for it, that's great. As for myself... it's overkill and way too expensive, I'll sacrafice a little handling going around the corners.
