What is your experience modifying motor vehicles? You can determine whether or not wheels can be interchanged by looking at the specifications of the wheels - things like the bolt patterns, the center hole and the rim offset - once these indicate that the wheel is suitable, you can then test fit to confirm.
A 95 Sidekick will have a 5x5.5 bolt pattern (5 holes on a 5.5" pitch circle) and a center hole I believe of 108mm - you can verify this by removing one of your wheels & measuring it - newer models of Suzuki upto around 2005 used these came dimensions, but on larger rims (16 rather than 15), so you're not limited to the Sport
