Ummm - I'm fairly certain the wheels off of Sammys, Trackers & most Vitaras also will not work - if I'm not mistaken the Sidekick Sport takes a 16" rim, 15s will not clear the front brake calipers - you're most likely going to have difficulty with most after-market 16s because of "inner rim" profile, wheels from the 99~05 Grand Vitara are your best bet.
