Tyre designations
Meanings:
e.g.
185/60 R 15 84 T
Speed code letters:

Tyre pressures
3
12-8.
Also may be shown on a label located
on the driver’s door pillar.
After having checked the tyre
pressures, securely tighten the valve
caps.
The specified tyre pressures are valid
for cold tyres. The increased tyre
pressure resulting from extensive
driving must not be reduced. The tyre
pressures specified apply to both
summer and winter tyres.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
