* Year: Wheel designs and bolt patterns changed over the years. A wheel from a 2003 Ram 2500 won't necessarily fit a 2023 Ram 2500.
* Model: Even within the same year, different trim levels or configurations (e.g., single rear wheel vs. dual rear wheel) might have different wheel bolt patterns, offsets, or wheel sizes.
* Bolt Pattern (PCD): This refers to the number of lug nuts and the diameter of the circle they form. A mismatch here will prevent the wheel from mounting.
* Wheel Offset: This is the distance between the wheel's mounting surface and its centerline. Incorrect offset can cause clearance issues with the suspension, brakes, or fenders.
* Hub Bore Diameter: This is the diameter of the hole in the center of the wheel that fits over the hub. Too small, and it won't fit; too large, and it will be unsafe.
* Wheel Size (diameter and width): While some variation is possible, drastically different wheel sizes might rub against parts of the vehicle or affect speedometer accuracy.
Before purchasing any wheels for your Ram 2500, you must verify compatibility. You can check your owner's manual or a reliable online resource like a tire and wheel retailer's website, inputting your vehicle's year, make, and model to see what wheels are compatible. Using a reliable wheel fitment tool is highly recommended.
