Have had these Summer season wheels and tires on my Vibe a while. Like them better than steels for sure. One thing I don't like is a wheel that is either too far inside the wheel well line or sticking outside the same line. My wheels/tire are 17" Borbet Type CA with a 38mm offset from TireRack with a 225/50 17 Kumho Ecsta LX Platinum tire. Quiet and durable tire, but
not for snow. Some pics that I could find...
This is the '03-'08 OEM wheel spec chart from the Toyota Matrix side of the house... works for us too. They had an extra hubcap version for their 16 inch steel wheel, so don't let that throw you off...
Whatever wheel you buy, make sure it's between 38 and 42mm offset. The OEM 17 has a 45mm offset. These figures work out of the '03-'08 models and are 5X100 bolt pattern. Not sure about the Second Gen. They have two bolt patterns to deal with, I think.
There are a bunch of great looking wheels you can find for Vibes. I wish I had gone with a 225/55 17 tire to make it more SUV like. Next tire.
