Its so not your weight...220 isn't that heavy.

Are the Rubinos the tyre you switched to or from? I don't know much about them. But if you've checked rim tape and changed to bullet proof tyres (try some marathons or gatorskins) I reckon your next port of call is to drop the wheel (Im assuming the issue is confined to one wheel?) to the LBS and have the spokes checked...then its off to Wiggle for a new wheelset!
