I have had the same problem
I have had the same problem with my 2015 Rubicon. Took it in multiple times, both in and out of warranty. Was told to get different tires than the ones that were OEM!!! Those tires were not meant to drive on freeways. WTF??? I replaced the front tires that had uneven tread about 9 months ago and the problem has come back, worse than before.
