* Reduced ground clearance: The larger tires will raise the vehicle's center of gravity, making it more likely to tip over.
* Increased wear and tear on the suspension: The larger tires will put more stress on the suspension components, causing them to wear out more quickly.
* Reduced fuel efficiency: The larger tires will increase rolling resistance, which will reduce fuel efficiency.
* Speedometer inaccuracies: The larger tires will cause the speedometer to read higher than the actual speed, which could lead to speeding tickets.
In addition, 22 inch rims may not fit properly on the 1988 Chevy Caprice. The original wheels are designed to have a specific offset, which is the distance between the mounting surface of the wheel and the centerline of the wheel. Installing wheels with a different offset can cause the tires to rub against the fenders or other parts of the vehicle.
For all of these reasons, it is not recommended to install 22 inch rims on a 1988 Chevy Caprice.
