Few things to consider:
If the wheels are larger diameter than the originals, the tent may not peg down properly when folded out, due to increased trailer height,
You may lose wheel clearance in the guards, limiting suspension travel,
The offsets may cause clearance issues with inner/outer guard as mentioned above.
Sometimes you luck out, but sometimes it's probably not worth the grief, and easier to just carry an extra spare if need be..

P.s. Just been through this excercise with my own trailer, and in the end gave up on matching car.
