* Wheel Well Clearance: The 1996 Brougham's wheel wells were designed for much smaller diameter wheels. 22-inch rims, with tires mounted, would almost certainly rub against the fenders, suspension components, or bodywork, even with minimal suspension lift.
* Suspension Geometry: Larger wheels significantly alter the suspension geometry. This could lead to poor handling, premature wear on suspension parts, and potentially unsafe driving conditions.
* Brake Caliper Clearance: The increased wheel size might interfere with the brake calipers.
* Speedometer Calibration: The larger wheels will alter the speedometer's accuracy, making it read slower than your actual speed.
* Ride Quality: Expect a much harsher and less comfortable ride with larger wheels and tires designed for performance over comfort.
While some modifications *might* be possible (like extensive fender rolling, suspension lift, and custom offset wheels), it's a complex, expensive, and potentially risky undertaking. It would require the expertise of a skilled mechanic or custom wheel shop and is generally not recommended. Sticking to wheel sizes within the factory specifications or slightly larger (perhaps 18 or 20 inches, but only after thorough research for compatibility), is a much safer and more practical approach.
