6. Winter Tires
In low temperature conditions, Pirelli recommends the fitment of 4 winter tires of the same line.
Please check your vehicle owner’s manual concerning winter tire size recommendation. If the
winter tires have a lower speed rating than the original equipment tires, vehicle handling may be
affected, and the vehicle maximum speed must be reduced to the winter tire speed rating.
If using studded winter tires, Pirelli recommends that studded tires be installed on all four
positions.
Please note that studded tires are not legal in all jurisdictions. Please check the
applicable legal requirements before installing studded tires.
Please note, for both winter tire and studded tire usage, if such tires are applied to the front axle,
they must also be applied to the rear axle.
7. Run Flat Tires
Always refer to the vehicle owner’s manual with respect to specific safety and operating
information relating to the vehicle. Damaged Run Flat tires or Run Flat tires that have
experienced a loss of pressure should immediately be replaced with another Run Flat tire of
identical size and Service Description (Load Index and Speed Symbol).
Run Flat tires have been developed based on the specifications of the vehicles on which they
are mounted. Accordingly, Run Flat tires should only be mounted on vehicles specifically
manufactured to accommodate Run Flat tires.
Run Flat tires must be mounted in conjunction with a functional Tire Pressure Monitoring
System (TPMS).
The mounting of tires and installation of the Tire Pressure Monitoring System (TPMS) should be
carried out by an authorized Pirelli dealer.
8. Pirelli “Seal Inside” Technology
Select Pirelli tires incorporate “Seal Inside” technology, a construction designed to reduce the
loss of air from a tire in most circumstances when the tire tread is punctured by an object. The
“Seal Inside” technology is not designed or intended to be a permanent repair. Should the “Seal
Inside” technology be activated, immediately drive your vehicle to an authorized Pirelli dealer for
an inspection to determine if repair or replacement is needed.
9. Pirelli Noise Canceling System
Select Pirelli tires are constructed with Pirelli Noise Canceling System (PNCS). This is a
technology that reduces the tire cavity noise caused by the vibration of the tire structure when
rolling on the road surface, which is one of the major factors generating noise inside the vehicle.
