* Bolt Pattern (PCD): This refers to the number of lug nuts and the diameter of the circle they form. A 1997 Jeep Cherokee typically has a 5x4.5" bolt pattern (5 lug nuts on a circle with a 4.5-inch diameter). You *must* match this precisely.
* Wheel Offset: This measures the distance between the wheel's mounting surface and its centerline. Offset significantly impacts how the wheel sits in the wheel well. Incorrect offset can cause rubbing against suspension components or the body. You'll need to find a wheel with an offset similar to your stock wheels. The exact ideal offset range will vary, so consult a resource like a wheel compatibility chart.
* Wheel Diameter: This is straightforward – the diameter of the wheel (e.g., 15", 16", 17"). Larger diameter wheels often require different tires to maintain the same overall diameter (and speedometer accuracy).
* Center Bore: This is the hole in the center of the wheel that fits over the hub. The center bore needs to be either the correct size or slightly larger (using hub-centric rings to ensure proper fit).
* Backspacing: Closely related to offset, backspacing is the distance from the wheel mounting surface to the inside edge of the wheel. Similar to offset, incorrect backspacing can cause fitment issues.
In short: While many wheels *could* fit, you must verify the bolt pattern, offset, center bore, and diameter to ensure a safe and proper fit. Using a wheel compatibility chart or consulting a tire and wheel professional is highly recommended to avoid damage to your vehicle. Failing to match these specifications correctly can lead to wheel rubbing, damage to suspension components, or even dangerous wheel separation.
