To be sure, you need to:
1. Identify the exact model and trim level of both Jeeps. (e.g., 2008 Jeep Wrangler Unlimited Rubicon vs. 2005 Jeep Grand Cherokee Laredo)
2. Determine the wheel bolt pattern (lug pattern) for both vehicles. This specifies the number of lug nuts and the distance between them. (e.g., 5x4.5, 5x5, 6x5.5)
3. Check the wheel diameter and width. The diameter will determine the overall size of the wheel, and the width must be compatible with your Jeep's wheel wells.
4. Compare the wheel offset. This is the distance between the mounting surface of the wheel and the centerline of the wheel. Incorrect offset can cause rubbing or clearance issues.
If all these specifications match exactly, then the wheels *should* fit. However, it's always best to double-check with a tire professional or consult your Jeep's owner's manual for the correct specifications.
