If that is the nose end closest to the camera, then the tilted one is most likely back truck and you are goofy footed?
Heel side will always have more impact and especially if you ride tight trucks, the bushings just will not bounce back the way they are supposed to when they are done up too tight, especially right from go, when they need some break in time.
If you have stock bushings in those Ventures, they are medium hard to start with, but will definitely stay a certain way if cranked down and have hard heel landings.
