Tyre Designations; Tyre Pressure - Chevrolet 2012 Malibu Owner's Manual

In accordance with country-specific
regulations, affix the speed sticker
in the driver's field of view.

Tyre Designations

e.g., 225/55 R 17 95 H
225 = Tyre width, mm
55 = Cross-section ratio (tyre height
to tyre width), %
R = Belt type: Radial
RF = Type: RunFlat
17 = Wheel diameter, inches
95 = Load index e.g.,
95 is equivalent to 690 kg
H = Speed code letter
Speed code letter:
Q = up to 160 km/h
S = up to 180 km/h
T = up to 190 km/h
H = up to 210 km/h
V = up to 240 km/h
W = up to 270 km/h

Tyre Pressure

Check the pressure of cold tyres at
least every 14 days and before any
long journey. This also applies to
vehicles with a tyre pressure
monitoring system. Unscrew the
valve cap.
The recommended tyre pressure is
shown on the label attached to the
vehicle's centre pillar (B-pillar). See
Vehicle Load Limits on page 8‑10
and Tyre Pressure on page 11‑6 for
more information. The tyre pressure
data refers to cold tyres.
Vehicle Care
It applies to summer and winter
tyres. Always inflate the spare tyre
to the pressure specified for full
load. The ECO tyre pressure
serves to achieve the lowest fuel
consumption possible. Incorrect tyre
pressures will impair safety, vehicle
handling, comfort, and fuel economy
and will increase tyre wear.
{
WARNING
If the pressure is too low, this
can result in considerable tyre
warmup and internal damage,
leading to tread separation and
even to tyre blow-out at high
speeds.
If the tyre pressure shall be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
