7/3/25, 10:30 AM The Most Common Mistakes In The Care And Use Of Your Car's Tyres

Incorrect tyre pressure:

Whether through carelessness or lack of knowledge, many drivers do not
regularly check their tyre pressure. This is not at all advisable: driving with a tyre
pressure below that recommended by the vehicle manufacturer can lead to
premature tyre degradation (especially on the sidewalls), carcass fatigue, a high
risk of a blowout and increased fuel consumption. Nor should you drive with high

tyre pressure, above the recommended load: the rubber contacts the road less
and loses grip, premature degradation occurs in the central part of the tread and
the vehicle's dynamic behaviour is worse.

To avoid all these problems, it is best to check the tyre pressure (when cold) once
a month or before a long journey. The manufacturer's recommended tyre

pressure is given in the vehicle handbook.

Do not rotate tyres to extend tyre life:

Front and rear tyres are subjected to different work and loads, so wear is very
uneven. Rotation is essential to achieve more even wear and thus increase the
service life of all tyres. Even and regular tyre wear on both axles of the vehicle
contributes to increased safety on the road, the axles react

in a balanced way and the driver has better control of his vehicle. It is advisable to
rotate them between axles every 10,000 kilometres (or as stipulated by the
manufacturer).

Excessive or uneven wear:

Regardless of a tyre's service life, its tread depth should be checked from time to
time. According to the law, it must have a minimum tread depth of 1.6 mm, a legal
limit that is referenced by the wear indicators, marked by an indicator in the
shoulder area of the tyre. One trick to check for wear is to insert a euro into the
tyre tread: if you can see the gold edge, it is time to change it.

Equally important is to check that the wear is even. Front axle tyres, because of
the configuration of the vehicle, usually show uneven wear between the outer and
inner shoulder. A tyre that is in good condition on the outside may be 'eaten' on

the inside.
