Rim Inner Edge Position?

[mikysee]

I was looking at the offset calculator and I was wondering if someone can explain the Rim Inner Edge Position number. What number is considered acceptable? When I entered 9.5 width and 25 offset I got 4mm LESS. Is that ok for front and back?
Thanks for any help.

Rim Inner Edge Position is how far the wheel extends inside. 4mm less is very minimal and your 25 offset on a 9.5 will be fine and be better than stock (imo)

4mm less from the stock wheel. so, when you are looking at your stock rim...your new rim will be 4mm closer to the strut housing.
