RIMS AND TYRES

Pressed steel or alloy rims.
Radial tubeless tyres.
The log book shows all the homologated
tyres.
IMPORTANT In the event of any dis-
crepancies between this Handbook and the
car Log Book, only the latter should be con-
sidered.
While the specified dimensions remain the
same, for driving safety, the car must be fit-
ted with tyres of the same brand and type
on all wheels.
IMPORTANT Do not use inner tubes
with Tubeless tyres.

between sides).
55
= Percentage height/width (H/S)
ratio.
R = Radial tyre.
ZR = Radial tyre, with speed over 240
A0A0718m
km/h.
16 = Rim diameter in inches (Ø).
91 = Load index (capacity), e.g. 91 =
615 kg. Not present in ZR tyres.
W, Z = Maximum speed index. In ZR tyres
the speed index Z is before the R.
