I've been debating over this for ever it seems, just wanted some opinions...

I've decided between either RH C2 evos, or Velox VX8...but because both have deep lips, which make them appear to be smaller, I can't decide which size to go with and what series tire.

Here are my choices originally:

For 17"s, either a 205/40 or 215/45 series tire
and 18"s, either a 215/35, 225/40, or 225/35 series tire...

Im leaning towards the 18s, in 215/35/18 series tires, but I'm afraid It wont be a smooth ride with the sportlines I have. Any input would be greatly appreciated!!
