I have 2013 F150 XLT, 6.5 bed, less than 600 miles on it. Hated the tires that came on it because of the vibrations and noise the Grabbers made so I traded them on some Michelins. Cutting to the chase the truck vibrates at 55. Had the tires rebalanced today and seem great until a smooth road at exactly 55 mph. Not 58. Not 53. Is this strange or do I remember other F150s with this problem and what, if anything, did Ford do? Love my truck...just got to get the vibrations out.
