Volkswagen Golf Service & Repair Manual: Outer shoulder wear
| Unsuitable use of self-levelling adjustments on pneumatic
suspension system |
| The use of the offroad level is recommended only for driving
offroad. Permanent use of the offroad level during normal road
operation can lead to increased tyre wear as the height of the
wheel position is different to the road level. |
| The way to prevent one-sided tyre wear is to ensure the
wheel alignment is correct on one hand and on the other hand to
make sure the vehicle is used only for its intended purpose: |
| Regular servicing of the vehicle and tyres helps to prevent
tyre wear. The following should be noted in particular with
regards to this: |
| The prescribed minimum tyre inflation pressures must be
adhered to. |
| Different wear on the front and rear axle depending on the
driving style is unavoidable. This condition can be compensated
for by rotating the wheels from front to rear. The ideal
opportunity to do this, for example, is during the seasonal
change between winter and summer tyres. This change also has a
positive side effect in that the tyres can wear down equally,
meaning that a completely new set of tyres can be fitted. This
prevents differences between the tread depths of the tyres on
each axle, which can have negative effects on road holding. |
| Saw tooth formation is a normal wear pattern, particularly
if the driving style is very careful
→ Chapter. This can lead to increased rolling noise,
which generally becomes less as the tread depth decreases. In
the event of light saw tooth formation or if saw tooth formation
is just starting, exchanging the wheels between axles is
normally sufficient. If saw tooth formation is very pronounced,
the wheels have to be changed in accordance with
→ Chapter so their direction of rotation is reversed.
This does not apply for tyres with a directional tread pattern. |
| Some tread patterns may create an impression of premature
wear: if winter tyre sipes or channels in the tread are worn
down, only compact profile blocks without patterns remain, thus
giving the impression of a worn tyre. In this case, the
remaining tread depth must be measured in each groove. If this
is at or below the minimum tread depth, the tyre can continue to
be used without restrictions. (In Germany, the minimum is 1.6
mm; it is recommended, and in Austria, required, that winter
tyres that are worn down to 4 mm be used only in summer ) |

This is often caused by driving style, but can be the result
of incorrect wheel alignment.
