Here's why:
* Wheel well clearance: The 1994 Town Car's wheel wells are designed for much smaller diameter wheels and tires. 22-inch rims with tires would be far too large, resulting in serious rubbing against the fenders, suspension components, and possibly even the body.
* Offset and bolt pattern: Even if you could physically fit the rims in the wheel wells, the bolt pattern (number and spacing of lug holes) and offset (how far the wheel's mounting surface is from the centerline) of 22-inch rims are unlikely to match the 1994 Town Car's specifications. This would require custom-made rims or potentially dangerous wheel adapters.
* Suspension interference: Larger wheels and tires significantly alter the car's center of gravity and could put excessive stress on the suspension, potentially causing damage or failure. The stock suspension isn't designed for such a dramatic change.
In short, while it *might* be *physically possible* with extensive custom fabrication (including potentially modifying the suspension, fenders, and possibly even the body), it's highly impractical, expensive, and likely to compromise the safety and reliability of the vehicle. Sticking with wheels and tires designed for the car is strongly recommended.
