Just in case anybody is considering these tires for their X350 - I put them on the front of my car to replace Continental tires after a great experience with Hancook tires on a Porsche Cayenne. Unfortunately, I found them very noisy and hard after the Contis and switched them to the back of the car where road noise and stiffness is much less pronounced. I will need to replace the Continentals at the front soon but before I do, can anyone recommend an 18" tire built for comfort and low road noise which might be better?

Michelin makes some very nice tires,.
Best motorcycle tires i've EVER had!!!!
Have always had good luck with their car tires as well.

 

I think I will go back to the Contis. I think they were specified by Jag from new so should be "tuned" for the xJ8.

OEM is not a bad way to go at all, many people do, and are happy, best of luck to you.
