Wheel Spacers

You are on the right track. The 05+ Wheels usually need 1" spacers, possibly more on sn95s.

At a minimum you'll need a quality hubcentric bolt on spacer, along with upgrading the studs.

Second issue is tires. 245/45/19s are too big in terms of OD for the SN95. That's 2" larger in diameter. Ideal size for SN95 is 245/35/19. Not a cheap tire

If you could find the offset and Backspace specs of the particular wheel you got, you could compare to SN95 wheels and figure out a spacer size
