and yes i did see the fitment guide.... wondering if a 16x7 w/225-45-16 will fit my 05 xa??? without any rub....thanks in advance

Should be fine... what's the offset?

yah your off set will make the difference. you shouldn't have any problems with a 16x7. i think a 225 45 would look a little funny on a 7" wheel
check this out, best tire/wheel calculator ive ever used

OK...just to be sure....
I'm riding down the highway, behind the xA, thinking it needs to have the wheels pushed out to the edges of the fenders....the wheels that would do that would have a more positive or less positive offset? Or is that dependent on the wheel width?
