2017 FIAT 500E wheel size

Refer to the “Maintenance Schedule” for the proper
maintenance intervals. The reasons for any rapid or
unusual wear should be corrected prior to rotation
being performed.
The front and rear wheels are different sizes and cannot
be used in place of each other. Rotate the wheels
“side-to-side” as shown in the diagram.
DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were estab-
lished by the National Highway Traffic Safety Ad-
ministration. The specific grade rating assigned bythe tire’s manufacturer in each category is shown on
the sidewall of the tires on your vehicle.
All passenger vehicle tires must conform to Federal
safety requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based
on the wear rate of the tire when tested under
controlled conditions on a specified government test
course. For example, a tire graded 150 would wear
one and one-half times as well on the government
course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their
use, however, and may depart significantly from the
norm due to variations in driving habits, service
practices, and differences in road characteristics and
climate.
Traction Grades
The Traction grades, from highest to lowest, are AA,
A, B, and C. These grades represent the tire’s ability

pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Refer to “Tires –
General Information” in “Starting And Operating” for
information on how to properly inflate the vehicle’s
tires. The tire pressure will also increase as the vehicle is
driven. This is normal and there should be no adjust-
ment for this increased pressure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low-pressure warning
limit for any reason, including low temperature effects
and natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold placard pressure. Once the low tire
pressure warning (Tire Pressure Monitoring Telltale
Light) illuminates, you must increase the tire pressure
to the recommended cold placard pressure in order for
the “Tire Pressure Monitoring Telltale Light” to turn off.
The system will automatically update and the “Tire
Pressure Monitoring Telltale Light” will turn off once
the system receives the updated tire pressures. Thevehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pres-
sure of 33 psi (227 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn ON
the “Tire Pressure Monitoring Telltale Light.” Driving
the vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the “Tire Pressure
Monitoring Telltale Light” will still be on. In this
situation, the “Tire Pressure Monitoring Telltale Light”
will turn off only after the tires are inflated to the
vehicle’s recommended cold placard pressure value.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system

CAUTION!(Continued)
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. The TPM sensor is
not designed for use on aftermarket wheels and
may contribute to a poor overall system perfor-
mance or sensor damage. Customers are encour-
aged to use OEM wheels to assure proper TPM
feature operation.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take your
vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor. NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
• Under-inflation also reduces the high voltage battery
range and tire tread life, and may affect the vehicle’s
handling and stopping ability.
• It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the “Tire Pressure
Monitoring Telltale Light”.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
212 STARTING AND OPERATING

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the radio.Push the switch to turn on the Hazard Warning
flashers. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncom-
ing traffic of an emergency. Push the switch a second
time to turn off the Hazard Warning flashers.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is
disabled and it is creating a safety hazard for other
motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flashers will continue to operate with
the ignition key removed and the vehicle locked.
NOTE: With extended use, the Hazard Warning flash-
ers may wear down your battery.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle, the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

the tire and remove any corrosion or loose particles.
