15" to 16" wheels...will they fit...?

Hi all,
I'm looking to go to 16x7 wheels changing from the 15x7's that are on my 2000 Mountaineer and have been looking at the 2002-2003 Mountaineer 16" wheels. Anybody know if these will bolt right on?
I'm assuming that tracking and stability (especially in cornering) will improve by making this switch. Is my thinking correct? The other issue is that my speedometer reads 3 mph fast at all speeds and by doing this will correct the high reading.
Thanks for any input you have.

you can go either way and the wheels will fit... no problem. I went from 16X7 to 15X8 on my wife's Sport..... too bad... should of went to 16X8 for better cornering... but she doesn't race her truck anyway so it doesn't matter..... wider is better though.
