TireRack says that the A/S3+ has relatively good rolling resistance vs. comparable tires. A couple MPG and slower acceleration is either your ass dyno, a change in diameter (if they are meaningfully bigger, you’ll record less distance traveled, and have the car geared up higher), or something coincidentally went wrong on the car.
