Reasons for flattening
♦ The vehicle is left standing for several weeks without being
used.
♦ The tyre pressure is too low.
♦ After being painted, the vehicle was left in the drying kiln of the
painting workshop.
♦ The vehicle was parked while the tyres were hot in a cold ga‐
rage or similar place for a long period of time . In this case,
flattening may even occur overnight.
Solutions in the event of flattening
♦ The flattening out of tyres can not be corrected using workshop
tools.
♦ This flattening out can only be removed by driving on the tyre
until it warms up.

wintry weather.
Requirements/conditions
– If necessary, check tyre pressure and correct.

Lateral deviation: verification

Points to check before and during the test drive:
– Check for possible damage to suspension components of the
front and rear axles.
– Check tyre pressure.
– Check tyres visually for exterior damage, punctures, cuts,
bulging sides, flattening and/or damage to the tread.
– Ask the client whether there have been any flat tyres which
were repaired in a workshop; replace the tyre if necessary;
– Check tyres for uniform wear and tread depth.
– Check all the tyres are the same type, make and have the
same tread pattern.
– If the tyres do not have a stipulated rotation direction, check
whether the tyre DOT markings are on the outside. If not, the
rims / tyres have been previously interchanged;
– The road surface should be straight and flat, without lateral
cambers or dips.
