If the tyre's speed code cannot be found, then
the tyre inflation pressure for the correspond‐
ing tyre size applies.
More information regarding wheels and tyres
can be obtained from a Service Partner of the
manufacturer or another qualified Service Part‐
ner or a specialist workshop.

WARNING
The inflation pressures on the tyre label
are applicable only for tyres explicitly men‐
tioned on the label. Since tyre inflation pres‐
sures for tyres that may be covered by the la‐
bel – by size, speed category and load rating/
load index – but not explicitly mentioned on the
label may be different. Please obtain adequate
inflation pressures in accordance with the tyre
manufacturer's specifications at your tyre
dealer.◀

nounced pulling to the left or right.
