Is 'Ideal' tread center even w/ bearing center?

[RABID_MP5]

I know the stock P5 offset is 50mm. I picked up some snows mounted on cheap 14" alloys with a 30mm offset. They clear the front calipers, fenders, etc. but make me wonder if I'm gonna stress the wheel bearings. So I start studying where the 2 bearing races actually are. And I conclude - I think - that the rotors are basically centered on the 2 bearing races (this MAY not be exactly true - but is close) Anyway, the rotor centers, front and rear are like 30 to 35 mm offset back from the plane of the wheel mounting surface. So, oddly, a 30mm offset seems more ideal bearing-wise than the 50mm offset stockers. i.e. the center of my 30mm wheels is almost centered between the 2 bearing races. Stock is a good 15mm inward.
So I'm just wondering if yeah, I'm actually fine with my wheels and also, why stock seems less friendly to the bearings (though how much I don't know)
Just thought I'd ask before I go ruin my bearings from something I'm not seeing.

No big deal. The reason for offsets is to clear suspension components and to work with existing suspension geometry. The way the bearings are made they can handle a lot of load changes, think of what happens when you are in major cornering loads or over bumpy surfaces. You have to worry less about the lever arm action to the bearing (as you are talking about) and more about "scrub radius".
Scrub radius is centering the tread surface in line with the steering axis. Ideally the imaginary line drawn from the steering axis should intersect with the centerline of the tread where it meets the pavement.
I'm tired of typing...
Don't worry about it.

oh yes, the "kingpin" angles of where the pivot movement is happening. I'll study that a bit till I'm satisfied. Guess the real test is just mount em up and test the handling.

yeah, just that there are no kingpins in strut front suspensions.
