* Bolt Pattern: This refers to the number of lug nuts and the spacing between them. Find the bolt pattern for both the 1994 and 1998 Caravan wheels (e.g., 5x4.5", 5x114.3mm). They *must* match exactly.
* Wheel Size (Diameter and Width): Even if the bolt patterns match, the wheel diameter (e.g., 14", 15") and width might be different. A significant difference could cause clearance issues with the brakes, suspension, or fenders.
* Offset: Wheel offset determines how far the wheel's mounting surface sits in or out from the hub mounting face. Mismatched offsets can affect handling and potentially cause rubbing.
To be certain: Find the specifications for the wheels on your 1994 and 1998 Caravans. This information is usually found on the wheels themselves (cast into the metal) or in your owner's manuals. If you can't find it there, a parts store or online database (like Tire Rack) can usually help you look up the specs based on the vehicle's year, make, and model.
Only if *all three* (bolt pattern, size, and offset) match exactly should you consider them interchangeable. Otherwise, it's highly risky to try.
