What is the correct wheel size for a 1968 Oldsmobile 442?

The correct wheel size for a 1968 Oldsmobile 442 depends on the options selected when the car was originally manufactured. There wasn't a single standard size. They commonly used 14-inch wheels, but some came with optional 15-inch wheels.

To know for sure what size wheels *your* specific 1968 Oldsmobile 442 should have, you need to check:

* The original owner's manual (if you have it): This will specify the factory-recommended wheel size.

* The trim tag: Located in the driver's side doorjamb, this tag contains a code that specifies the original options, including wheel size. Decoding this tag requires a reference guide specific to 1968 Oldsmobiles.

* The wheels themselves (if original): The size is stamped on the back of the wheel.

Without this information, assuming 14-inch is the most likely size, but it's crucial to verify before purchasing replacement wheels.
