I purchased (4 tires) 205/65R16 Sumitomo HTR A/S P02 for my vehicle in January 2019. In the past few months I-??ve noticed a constant rumbling noise from the rear while driving. I have had my vehicle serviced for an inspection and oil change. Each time I received no recommendations during the multipoint inspections related to my tires. The last time I took it in I mentioned that I planned to purchase new tires and the mechanic looked at me strangely. He measured that my tire thread were at a 6 and he could not see any visible defects. Once the tires were rotated the noise moved from the back to the front. There is clearly a defect with the tire and it is out of warranty to be replaced.

Premature tire wear. Car has 11,500 miles. Tire wear as measured by the dealer is 5/32 rear and 4 /32 front. Neither dealer or tire manufacturer kumho thinks this is an issue or is willing to take any action. Both claim tire wear is not warrantied. Tires should not wear out this quickly and it seems obvious that the tires are not properly specified for this car, 2013 Hyundai Sonata.
