However, there are a few other factors that can affect whether or not rims will fit from one vehicle to another, such as the wheel offset, which is the distance from the mounting surface of the wheel to the center of the wheel. If the wheel offset is too different between the two vehicles, the rims may not fit properly or may cause the tires to rub against the fenders or other parts of the vehicle.
Additionally, the size and width of the tires on the rims should be considered to ensure they are compatible with the vehicle's suspension and wheel wells. If the tires are too large or too wide, they may rub against the fenders or other parts of the vehicle, causing damage or posing a safety risk.
To be certain that the rims from the 1999 Dodge Ram 1500 4x4 will fit properly on the 2004 model, it is recommended to compare the lug nut pattern, wheel offset, and tire size of the rims to the specifications for the 2004 Dodge Ram 1500 4x4. If there are any differences, it may be necessary to purchase aftermarket rims or wheel spacers to ensure a proper fit.
