Yea I guess I should have clarified my first post. I have 16's on now, there is plenty of side wall and bumps in the road aren't too noticeable.I am trying to decide wether to get 18's or 20's. The side wall looks fairly thin on the 20's so I figured the ride would be rougher than the 18's. I'll probably end up getting 20's though since they look sweet. Nice choice in rims too. I plan on getting Zenetti Five rims.

 

I wonder whats the max on side wall that you can go with 20's, any one?
