Steering effort for manual 16:1 - should it be this high?

The subject has been pretty well covered by now, I dont know how much this will help. But when I had the original tires on the front (about 145ish width) I had disconnected the power steering pump so that it would have no assist. To my understanding this would put me at about a 16:1 ratio and it wasnt too difficult at all to turn at any speed with the standard steering wheel. As soon as I upgraded to larger tires up front (225 width) with the more aggressive alignment (not as aggressive as yours but close) it was much harder than I liked trying to parallel park so I ended up connecting the power assist again. That extra traction in the front made a huge difference.

P.S. I love your steering wheel, do you remember where you got it?
