I have not lifted my VX...yet. But I can say this. The amount of trimming will depend on your wheel width and offset. Wider wheels will cause the tire to well...be a little wider than if it were mounted an a narrower rim. Add any difference in offset and that puts the tire even further out past the wheel well. I would wager that people that say no or little trimming are still using stock or a 7" aftermarket rim. People that are calling up Clergy may be using an 8" or wider rim and have a different offset.
