The Nissan center-bore is really snug and you should relieve the opening just a bit with a Dremel or similar. If you're experienced with such things as engine porting then a die-grinder with a carbide bit would make it a quick job, otherwise just use the drum-sander attachment for the Dremel. You only need to remove about .5mm of material around the perimeter. If you don't, you'll soon hear a clunking sound from up front which will be the wheels you thought were on tight.

I've fitted wheels from both the Armada and Frontier, but went with the Frontier wheels 'cause they were 15's.
