WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load. Use of the temporary spare tire when towing can result in failure of the spare tire and/or less stability of the vehicle.
Make sure that all the tires on your vehicle are properly inflated. Refer to "Tires" F12- 8.
Trailer tire condition, size, load rating and proper inflation pressure should be in accordance with the trailer manufacturer's specifications. Also check federal, state, province and/or other applicable regulations.
In the event your vehicle gets a flat tire when towing a trailer, ask a commercial road service representative or professional to repair the flat tire.
If you carry a regular size spare tire in your vehicle or trailer as a precaution against getting a flat tire, be sure that the spare tire is firmly secured.
