I bought my wife a new 2014.5 Camry SE last week. I drove it off the lot and home for her, she was with me. It had a bad vibration starting at 40 and got really bad at 70 on the Interstate.
I took it in a few days ago, and they tried balancing the tires, road force. And could not get it to leave.

So they replaced all four tires with new GoodYears. Rides like a dream now !

 

Nice!

 

Hmm... The tires might be expired, what were the manufactured date of each tires? To check its (I learned this info from 4wheelonline blog) find a 4 digit number in the tire wall. Example 2011, where as 20- 20th week of 11-2011. Tires should be replaced every 6 years for safety reason.
