What is the tow capacity for a 1992 Toyota Corolla?

The 1992 Toyota Corolla did not have a significant towing capacity. Toyota did not design this vehicle for towing. While you might be able to pull a very small, lightweight trailer (like a very small utility trailer with minimal weight), it's strongly discouraged. Attempting to tow anything beyond a negligible amount would be unsafe and could damage the vehicle. There's no official towing capacity listed because it wasn't intended for that purpose.
