I have been looking at the 17" HFP's.
Wheel weight and tire weight are important This is not like adding a 200lb subwoofer in the trunk (which is pretty stupid), this is far worse. The thing about wheels is you have to spin them, and that takes much more effort than it does to move an object that isn't spinning. You're dealing with the polar moment of inertia.
In fact, just for fun I looked up how much straight-line performance you'd lose by switching from 16" wheels to 17" wheels if the wheels weighed the same. It'd be about like adding 200 static weight to the car, which would take an additional 11ft-lbs of torque (roughly 15hp @ the rev limiter) to compensate and get the same acceleration as a stock car. That's bad enough.
But no 17" wheel is as light as the stock 16's. What will the total combination?
How much static weight will be added to the car. Think about that number. If for example it was almost 30% of your car's entire weight. In order for the car to accelerate like it did STOCK, you'd have to gain back 42ft-lbs of torque over the ENTIRE rev range. At the rev limiter, you'd need to be making 55 extra horsepower. Not gonna happen without forced induction. So basically, you'll need to supercharge your car to keep pace with a stock 16" wheels.
Bling bling though, right?
Now you know why people with big rims get laughed at. Clowns wear big shoes too, but they're supposed to be funny.
Oh, and that's assuming you get the tires to fit in the first place, and then manage to make it over a pothole. You should aim to keep the volume of air in a tire constant when plus-sizing, which is why you should always upgrade to a wider wheel and wider tire when plus-sizing (a reason why Porsche uses hollow spokes!).
Oh, and I almost forgot to mention- that extra weight that you're adding to the vehicle? You're going to have to slow it down, too. Good thing the Civic has four wheel disk , cause you're going to need every ounce of them.
