Does anyone know what the stock wheel offset is for the 5th gen EX sedan? The wheel size is 15 X 6.5

I have the Helms manuals, but they do not give the offset. In the owner's manual it says the wheel has a 'JJ' profile, whatever that is.

The reason I ask is that I'm thinking about going to a 16" wheel, and I want to keep the same geometry as stock.
