I've had the tires for about 2 years, and in the past few months noticed a chugging feeling when I'd be driving in idle (no gas or brake applied) through a parking lot. It wasn't noticable though at high speeds.
I asked about it when I had the oil changed and tires rotated, and the technician at the Goodyear Service center told me that there was a definite "bounce" in the tire, and that it was made worse when he rotated the tires. So he put them back the way they were and called Goodyear. As a result of whatever was wrong, I am now getting a new set of tires courtesy of Goodyear.
Has anyone else had similar issues with the tires or is this a one-off defect?
