If I stick with 17s, is it acceptable to switch to 225/45R17s or 235/45R17s (seems to have closer overall diameter to the stock tires) from the stock 215/50R17s? This way I could get better tire.
The higher the wheel height the more performance is lost. The taller wheels are the more the torque has to work to spin the wheel, therefore decreasing torque, and displacing HP. I'd go with some wide 16 or 17's.
