Wheel weight is a major concern as affects performance, gas mileage, braking, and ride; all negatively. As you go larger, the weight is further from the center with all the same problems. Think of the wheels as four large flywheels. If you look ar the Honda specs, you will see that the gas mileage drops by 2 mpg just going from the EXL 17” wheels to the 19” on the Sport and Touring. Acceleration and braking are afffected similarly. As repeated on here many times, expect more opportunities for curb rash and pothole damage as you decrease the profile. Tires are way more expensive as well.
