Need some clarification on wheel offset

[DarksideSurf]

What are the specs on 17" OEM Limited wheels, and what would happen to the geometry of the suspension if I upsized both the diameter and the offset ? I'm hoping there won't be any adverse side effects, but since the only experience I've had with rims was on my Accord a few years back I don't have the slightest clue what it would do to my 4WD 4Runner.

The reason I'm asking is because I can get a set of Chevy Silverado SS 20" rims free and clear. They're the same lug pattern, but their offset is 25mm.

+30MM OFFSET

I think the offset on the Limited 17" wheels is +30mm.

I think the offset on the Limited 17" wheels is +30mm.

+30 ??? Looks like the wheel should be compleatly inside the suspension.

since we're talking about 17'' stockies, would going up to 275 60 rub?
