Towing Requirements – Tires

− Do not attempt to tow a trailer while using a compact spare tire.

− Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires – General Information” in “Starting and Operating” for information on tire pressures and for proper tire inflation procedures.

− Check the trailer tires for proper tire inflation pressures before trailer usage.

− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires – General Information” in “Starting and Operating” for information on tread wear indicators and for the proper inspection procedure.

− When replacing tires, refer to “Tires – General Information” in “Starting and Operating” for information on replacement tires and for the proper tire replacement procedures. Replacing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits.
