FRONT WHEEL DRIVE WITH
SELF-LOCKING DIFFERENTIAL
(upon request for versions/
markets where applicable)
Alfa Q2characteristics are such as to
guarantee top performance with whatever
road condition.Alfa Q2features front wheel drive with
front mechanical self-locking differential LSD
(Limited Slip Differential). Torque level be-
tween right and left wheel is modulated ac-
cording to the TORSEN Bfront differen-
tial grip. Mechanical modulation is continu-
ous and gradual thus optimizing drive under
whatever running condition and guarantee-
ing smooth drive, high stability and keeping
top comfort conditions.This type of differential enables to exploit
the tyre-road grip at the best even under
poor grip conditions: the driver is however
charged with observing common safety rules
since road safety is always the driver's re-
sponsibility.

WHEELS
RIMS AND TYRES
Pressed steel or alloy rims.
Radial tubeless tyres.
The log book shows all the homologated
tyres.
IMPORTANTIn the event of any dis-
crepancies between this Handbook and the
vehicle Log Book, only the latter should be
considered.
While the specified dimensions remain the
same, for driving safety, the vehicle must be
fitted with tyres of the same brand and type
on all wheels.
IMPORTANTDo not use inner tubes
with Tubeless tyres.
COMPACT SPARE WHEEL
Pressed steel rim.
WHEEL GEOMETRY
Front wheel toe-in measured from rim to
rim: –1 ±0.6
The values refer to the vehicle travelling.
Example:

CORRECT TYRE READING
(fig. 5)
Below, please find the instructions need-
ed to understand the meaning of the code
stamped on the tyre.
The code may be in one of the ways giv-
en in the example.
205= Nominal width (S, distance in
mm between sides).
55= Percentage height/width (H/S)
ratio.
R= Radial tyre.
ZR= Radial tyre, with speed over 240
km/h.
16= Rim diameter in inches (Ø).
91= Load index (capacity), e.g. 91 =
615 kg. Not present in ZR tyres.
W,Z= Maximum speed index. In ZR
tyres the speed index Z is before
the R.

6,5=rim width in inches (1)
J=rim drop centre outline (side pro-
jection where the tyre bead
rests) (2)
15=rim nominal diameter in inches
(corresponds to diameter of the
tyre to be mounted) (3=Ø)
H2=“hump” shape and number (relief
on the circumference holding the
Tubeless tyre bead on the rim).
ET 43=camber angle (distance between
disk/rim line and wheel rim cen-
tre line)
