Roadside Emergencies WARNING: The use of tire sealants may damage your tire pressure monitoring system (TPMS) and should not be used. However, if you must use a sealant, the TPMS sensor and valve stem on the wheel must be replaced by an authorized Ford dealer. WARNING: Refer to Tire pressure monitoring system (TPMS) in the Tires, Wheels and Loading chapter for important information. If the tire pressure monitor sensor becomes damaged, it will no longer function. Dissimilar spare tire/wheel information WARNING: Failure to follow these guidelines could result in an increased risk of loss of vehicle control, injury or death. If you have a dissimilar spare tire/wheel, then it is intended for temporary use only. This means that if you need to use it, you should replace it as soon as possible with a road tire/wheel that is the same size and type as the road tires and wheels that were originally provided by Ford. If the dissimilar spare tire or wheel is damaged, it should be replaced rather than repaired. A dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is different in brand, size or appearance from the road tires and wheels and can be one of three types: 1. T-type mini-spare: This spare tire begins with the letter "T" for tire size and may have "Temporary Use Only" molded in the sidewall 2. Full-size dissimilar spare with label on wheel: This spare tire has a label on the wheel that states: "THIS TIRE AND WHEEL FOR TEMPORARY USE ONLY" When driving with one of the dissimilar spare tires listed above, do not: • Exceed 50 mph (80 km/h) • Load the vehicle beyond maximum vehicle load rating listed on the Safety Compliance Label • Use snow chains on the end of the vehicle with the dissimilar spare tire • Use more than one dissimilar spare tire at a time • Use commercial car washing equipment • Try to repair the dissimilar spare tire 332 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
