First Off, Welcome to Nico
Second, your car came OEM with 215/60/16 with a diameter of 26.2". With that said, you won't experience a significant drop in mileage as long as you stay within the stock diameter of your OEM tire size.
So if you selected 18's the best tire size would be 225/45/18 which has a diameter size of 26.0. That means if your speedo reads 60pmh, you're actually traveling 59.6 mph.
If you choose to go with 19", 225/40/19s would be have a diameter of 26.1. So if you're going 60mph, you're actually going 59.8mph
Keep in mind the size of the tire will have a direct relationship of how many revolutions per mile. Stock tire is 771.0. Obviously, a smaller tire will have more revolutions and a bigger tire will have less but this will impact the mileage on the car. That means if you go with a really smaller diameter tire, you're racking up miles on your odometer that aren't actually driving. Same goes for the inverse. So with all of that said, I'd stick to the tire sizes I mentioned above and your mileage shouldn't change....at least grossly!
