The usage of a full-size dissimilar spare tire/wheel can lead to
impairment of the following:
•Handling, stability and braking performance
•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
•All-Wheel driving capability (if applicable)
•Load leveling adjustment (if applicable)
When driving with the full-size dissimilar spare tire/wheel additional
caution should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire/wheel and
seek service as soon as possible.
Spare tire information
Note:If your vehicle is equipped the tire pressure monitoring system
(TPMS), the system indicator light will illuminate when the spare is in
use. To restore the full functionality of the TPMS system, all road wheels
equipped with the tire pressure monitoring sensors must be mounted on
the vehicle.
If your vehicle is equipped with TPMS, have a flat tire serviced by an
authorized dealer in order to prevent damage to the TPMS sensor; refer
toTire Pressure Monitoring System (TPMS)in theTires, Wheel and
Loadingchapter. Replace the spare tire with the road tire as soon as
possible.
T-Type/Mini-Spare Tire Information (Harley Davidson only)
Your vehicle may be equipped with a temporary spare tire. This spare
tire is considered “temporary”. Replace the temporary spare with a tire
of the same size, speed rating, and load carrying capacity as the other
road tires as soon as possible.
When driving with the temporary spare tiredo not:
•Exceed 50 mph (80 km/h)
•Load the vehicle beyond maximum vehicle load rating listed on the

transmission.
Note:Towing a 4x2 or an ESOF 4x4 vehicle with the rear wheels on the
ground for more than 50 miles (80 km) and/or in excess of 35 mph
(56 km/h) may cause damage to the automatic transmission.
Note:On Dual Rear Wheel (DRW) vehicles, an outer rear wheel must be
