Depends on the width. 45mm was the OEM value for the 15 x 6.5 rim. So ...
If the width of the rim is 6.5" or 7.0", then it will probably fit (of course, your tire size selection with the correct load index for the Q may be very limited, if any are available at all!).
If it is 7.5", then I think you may have problems with anything wider than 235mm or 245mm tires (will touch the suspension stuff in front).
If it is 8.0" or more, you will probably have problems.
If it is 8.5" or higher, I would not even attempt to fit it - it will not work, IMHO.
All the above are assuming a 45mm offset, of course. Other offsets may make it work better, or a spacer will be required to put the rim farther out (more under the rim). Personally, I do not like the idea of spacers (do a search for a post by Grant as to why spacers are evil!)
Hope that helps a bit ...
