White Highlander owner 
2017 Toyota Highlander SUV Limited 4dr SUV AWD (3.5L 6cyl 8A)
TIRE PROBLEM LIKE NEVER BEFORE ?????
 This may be isolated to my vehicle but, at about 8500-9000 miles on the 2017 Limited AWD, the tires began to vibrate and make a mild grinding noise.  The dealership rebalanced them and I suspect rotated the front to the rear.  It was taken back to the dealership for a more through test.  The problem was identified to be in the rear tires.  Added weights were installed on those tires.  I now have a new car that drives and sounds like I have off-road noisy grinding vibrating tires as low as 30 MPH on very smooth road surface.
