Flew from Dallas to Denver on Sunday to pick this 2013 Scion XB, car was used with only 3400 miles on it. Drove from Denver to OKC Monday afternoon/night, perfect weather and dry roads all the way. About 20 miles east of Denver on I-70 started hearing a strange sound, thought for a minute or so that a wheel bearing was talking to me, after a few miles the pavement changed and the noise vanished. This noise came and went all the way to Dallas based on the pavement surface, I have never heard a tire talk this much or at this DB level. Just ordered new Continental PureContact W/Ecoplus to solve the problem, have them on my wifes car and they are great.
