Vehicles with run-flat tyres 3
When switching wheels, e.g. w hen
switching to winter tyres, use run-fla t tyres
as there is no spare wheel or tyre repair kit
in the vehic le.
Run-flat tyres - see page 229.
Fitting new tyr es
Fit tyres in pa irs or in sets, which is even
better. Ensure tha t tyres on one axle are
z the same siz e
z the same design
z the same make
z and have the same tread pattern.
Fit directional tyres such that they roll in the
direction of trav el. The rolling direction is
indicated by a symbol (e.g. an arrow) on
the sidewall.
Tyres fitted opposing the rolling direction
(e.g. when a tyre is changed) should be
refitted as soon as possible. This is the only
way to obtain full benefit from the design
properties of the tyre.
