Wheels and Tires – Overview
Tire/wheel rim combinations
The following tire/wheel rim combinations are
available:
• 235/60 R16 V – 6.5X16 (*)
• 235/55 R17 V – 7.0X17 (*)
• 235/55 R17 V – 7.5X17 (*)
• 235/50 R18 V – 7.5X18
• 235/45 R19 V – 8.0X19
(*) Also available as tires with run-flat capabilities.
Use of snow chains
Snow chains are only approved for use with size
235/60R16 tires.
Fine chains with a link thickness of 10mm may be
used at speeds of up to 50 km/h (please refer to
the manufacturer's instructions).
Coarser chains with a link thickness of 11 to 14
mm may be used at speeds of up to 40 km/h
(please refer to the manufacturer's instructions).
Tire repair kit
If the tires used do not have run-flat properties then
the vehicle will be equipped with a tire repair kit.
A tire repair kit is located in the spare wheel well
in the luggage compartment.
The tire repair kit consists of:
• a compressor with a pressure gauge,
• a lead for voltage supply via the cigar lighter,
• an air hose,
• tire sealant.
A tire filled with tire sealant must be replaced with
a new tire after 200 km at the latest. Read and
observe the instructions regarding the tire low
pressure sensors (see lesson 4 – Tire pressure
monitoring system).
Instructions on handling and using the tire repair
kit can be found in a separate operating manual
that is enclosed with the tire repair kit.

In addition to the standard tires, run-flattires are
also optionally available. These tires have a
reinforced sidewall and provide the advantage that
the tire maintains its shape to a large extent even
in the event of insufficient tire pressure. This
ensures that the vehicle handling remains stable.
Advantage:
• These tires maintain their shape to a large extent, even in the event of insufficient tire
pressure. This ensures that the vehicle handling
remains stable.
Special wheel rims (EH2) and a tire pressure
monitoring system are needed for run-flat tires.
Standard tires can also be installed on the EH2
(EH = Extended Hump) wheel rims. Tires with
run-flat properties have the same size code and
the same appearance as standard tires.
With some tires, the code RFfor run-flat is included
in the tire designation, e.g. 205/55 RF16. Tires with run-flat properties have various different
codes on the sidewall, depending on the
manufacturer.
• The RFT logo
• "RUNFLAT" as an additional designation
• The additional designation "RSC" (RSC =
Runflat System Component)
• The additional designation "SSR" (SSR = Self
S upporting Run-Flat-Tire)
• The additional designation "SST" (SST = Self
S upporting Run-Flat- Tire)
WARNING: If a tire with run-flat properties
is used without air then the vehicle speed
must not exceed 80 km/h and the vehicle
must not be driven for distances in excess
of 80 km.
Note: Vehicles equipped at the factory with run-flat
tires do not feature a tire repair kit or a spare wheel.

Wheels and Tires
Inspection and Verification
Visual Inspection Chart
MechanicalWheel(s)Tire(s)
Tire pressure(s) * Wheel nuts
Wheel studs
* Vehicles equipped with a tire deflation detection system (DDS) must be inspected for correct operation using the Ford approved diagnostic tool.
To maximize tire performance, inspect the tires for
signs of incorrect inflation and uneven wear which
may indicate a need for balancing, rotation or
suspension alignment. Tires should also be
checked frequently for cuts, stone bruises,
abrasions, blisters and for objects that may have
become embedded in the tread. More frequent
inspections are recommended when rapid or
extreme temperature changes occur or when road
surfaces are rough or occasionally littered with
foreign material.
As a further visible check of tire condition, tread
wear indicators are molded into the bottom of the
tread grooves. When these indicator bands become
visible, new tires must be installed.
Tire Wear Diagnosis
Uneven wear is usually caused by either excessive
camber or excessive toe on tires.
Sometimes incorrect toe settings or worn struts will
cause severe `cupping' or `scalloped' tire wear on
non-driven wheels.
Severely incorrect toe settings will also cause other
unusual wear patterns.
Tire Vibration Diagnosis
A tire vibration diagnostic procedure always begins
with a road test. The road test and customer
interview (if available) will provide much of the
information needed to find the source of a vibration. During the road test, drive the vehicle on a road
that is smooth and free of undulations. If vibration
is apparent, note and record the following:
– the speed at which the vibration occurs.
– what type of vibration occurs in each speed
range.
– mechanical or audible
– how the vibration is affected by changes in the following:
– engine torque
– vehicle speed
– engine speed
– type of vibration - sensitivity: – torque sensitive
– vehicle speed sensitive
– engine speed sensitive
The following explanations help isolate the source
of the vibration.
Torque Sensitive
This means that the condition can be improved or
made worse by accelerating, decelerating,
coasting, maintaining a steady vehicle speed or
applying engine torque.
Vehicle Speed Sensitive
This means that the vibration always occurs at the
same vehicle speed and is not affected by engine
torque, engine speed or the transmission gear
selected.

Engine Speed Sensitive
This means that the vibration occurs at varying
vehicle speeds when a different transmission gear
is selected. It can sometimes be isolated by
increasing or decreasing engine speed with the
transmission in NEUTRAL or by stall testing with
the transmission in gear. If the condition is engine
speed sensitive, the cause is probably not related
to the tires.
If the road test indicates that there is tire whine,
but no shake or vibration, the noise originates with
the contact between the tire and the road surface.A thumping noise usually means that the tire is flat
or has soft spots making a noise as they slap the
roadway. Tire whine can be distinguished from axle
noise. Tire whine remains the same over a range
of speeds.
A complete road test procedure is described in
Section 100-04.
REFER to:
Noise, Vibration and Harshness (NVH)
(100-04 Noise, Vibration and Harshness,
Diagnosis and Testing).
