Best Tires for Quiet, Smooth Ride?
 

Just purchased a CPO 2013 ML350 w/29k miles. Only concern is that the ride just doesn't seem as smooth and quiet as I'd hoped. (Previous past 4 cars were all Lexus,which had softer ride.) Tires are original ContinentalCross Contact LX Sport. My husband thinks we should look into new ones. Any recommendations would be appreciated.

I highly recommend that you get the Michelin Latitude Tour HP tires.
