RIMS AND TYRES
Alloy rims. Tubeless tyres with radial car-
cass. The homologated tyres are listed
in the Log book.
WARNINGIn the event of discrep-
ancies between the information provid-
ed on this “Owner’s Manual” and the
“Log book”, consider the specifications
shown in the log book only.
On cars fitted with four-wheel drive, all
four tyres should be the same (brand
and track) to prevent damaging the 4-
WD system. The efficiency of the 4-WD
system however, is not jeopardized if
tyres with different wear conditions are
fitted.
