TYPES OF TIRES
WARNING
●
When changing or replacing tires, be sure all
four tires are of the same type (Example:
Summer, All Season or Snow) and construc-
tion. An INFINITI retailer may be able to help
you with information about tire type, size,
speed rating and availability.
●
Replacement tires may have a lower speed
rating than the factory equipped tires, and
may not match the potential maximum ve-
hicle speed. Never exceed the maximum
speed rating of the tire.
●
Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
