The other questions you post will have more subjective answers. But if all you want is an additional set of wheels for summer then get the same size as stock .. as long as they are lighter (or the same weight at least). You can go +1 is wheel size to 18" wheels - but again keep the weight at 22 lbs or less. Otherwise you will have a "performance decrease". NOTE: The 18" tires will be more expensive than the same tire in a 17" size.
Other people on the forum go +1 (or 2) and go wider because of looks, performance attributes, etc..
What I cannot figure out from your post is WHY you want to get 18" wheels? I know your decision is not performance based, so is it about asthetics from the shorter sidewall 18" tires?
Well mainly 18" for looks, yes. But I wouldn't mind getting wider tires for increased performance, it just confuses me too much as to what would fit and not cause problems. Sorry, when you say people go +1 or +2 are you referring to the width? so 18x9 instead of 18x8 or 7?
