To find compatible wheels, you need to determine your Grand Cherokee's specifications:
1. Bolt Pattern (PCD): This refers to the number of lug nuts and the diameter of the circle they form. Common bolt patterns for 1997 Grand Cherokees are 5x4.5" (5 lug nuts, 4.5" diameter circle) and 5x5" (though less common). This is the MOST crucial specification.
2. Wheel Diameter: This is the size of the wheel measured in inches (e.g., 15", 16", 17"). Larger diameter wheels often require different tire sizes to maintain correct speedometer accuracy and avoid rubbing.
3. Wheel Width: Measured in inches (e.g., 7", 8"). Wider wheels can also cause rubbing issues if not paired with the correct offset.
4. Offset: This refers to the distance between the wheel's mounting surface and its centerline. Positive offset pushes the wheel outward, negative offset pushes it inward. Incorrect offset can lead to rubbing against suspension components or the fenders.
5. Backspacing: Closely related to offset, backspacing is the distance from the mounting surface to the inner lip of the wheel. Incorrect backspacing can also cause rubbing issues.
How to find your Jeep's specifications:
* Check the inside of your existing wheel: The specifications are often stamped on the wheel itself.
* Check your owner's manual: It might list the recommended wheel specifications.
* Check online databases: Websites like Tire Rack or similar resources allow you to enter your vehicle's year, make, and model to find compatible wheel sizes.
* Look at your vehicle's sticker (usually in the driver's side doorjamb): This sticker may list tire sizes, which can provide clues about wheel size.
In short: Don't just assume wheels from another vehicle will fit. Use the specifications above to research compatible wheels from other Jeep Grand Cherokees (the same year or very close years are safest) or use online resources to find compatible wheels from other vehicles that meet the precise specifications of your 1997 Jeep Grand Cherokee. Incorrect wheels can be dangerous.
