What size tires are on a 1989 Chevy Cavalier Z24?
In short, there isn’t a single universal tire size for every 1989 Cavalier Z24. Most Z24s using 14-inch wheels rolled with OE tires in the P195/75R14 or P205/60R14 range, though exact sizing depended on the specific wheel package and build date. To know the exact size on a particular car, check the door jamb placard or the tire sidewall.
Common OE tire sizes for 14-inch wheels
For most 1989 Cavalier Z24s equipped with the standard 14-inch wheels, the following sizes were commonly installed from the factory:
- P195/75R14
- P205/60R14
These two sizes were chosen to balance ride comfort, handling, and speedometer accuracy on the 14-inch wheel configuration typical of early Z24 models.
Were 15-inch wheels available on the 1989 Cavalier Z24?
Some late-1989 models or dealer-installed options offered larger wheels. If your Z24 has 15-inch wheels, tire sizes historically associated with that setup varied by wheel design and regional availability, so the exact OE size can differ. Always verify with the door placard or the vehicle’s build sheet for the precise specification.
How to verify the correct tire size on your car
To ensure you replace tires with the correct size and maintain proper performance, follow these steps:
- Check the driver’s door jamb placard for the recommended tire size and inflation pressures.
- Inspect the sidewall of the currently installed tires for the size, printed in the format like “P195/75R14.”
- If the placard is missing or the car has aftermarket wheels, refer to the owner’s manual or contact a GM dealer to confirm the appropriate OE size for your specific wheel package.
These steps help ensure compatibility with the vehicle’s suspension, speedometer calibration, and overall safety.
Summary
The 1989 Chevy Cavalier Z24 did not have a single universal tire size. Most cars with 14-inch wheels used either P195/75R14 or P205/60R14 as original equipment, with variations possible based on the wheel package and production date. Always confirm the exact size on the door placard or tire sidewall, and use that size for replacements to preserve correct performance and readings.
