You posted in the Encore forum.

The short answer is the same with any car. It depends on conditions.

assuming the stock tire diameter of 26.62", final drive ratio of 2.86, transmission in OD at .71, speed 60 mph, the rpm is 1,538.

So you are saying you have 225/60x16 tires?
You could have a different final drive.
How long have you had the car and is this a something that has not occurred before?
Do you have a check engine light on?
The transmission may not be going into overdrive or the torque converter is not locking.
