2004 Solara tire problem

[gmajacquie]

I purchased a 2004 Solara V6SLE (certified) with 13,000 miles 3/29/06. I absolutely love this car but last month I started having a rather rough ride. I took it in to the dealer and was told that it is a tire issue. The tires are supposedly choppy. I have had the tires rotated and balance almost each time I have had the oil changed. How can tires that cost $150.00 each be choppy and need replacing @ 27,000 miles?

Sounds like an alignment or brake issue. Can they tell you why the tires are cupping like that?
