Been reading this forum for a couple years. Just registered few days ago. I've got an 09 vibe base 5speed.
Recently added 18x8 wheels with 235/40s . really like this car. Only 64k miles.
I just went from the stock 205/55/16 to 235/40/18 on some new 18x8 wheels. It is a firmer ride, but I wouldn't say rough. I really like the feel and the ride.
