PIRELLI TIRES

8. Tire Replacement
The tires fitted to your vehicle as original equipment were tested and  
ap
 proved by the vehicle manufacturer and the tire manufacturer and  
take into account all aspects of the vehicle’s operation. Changes in the  
tire  size,  type  or  construction  should  not  be  made  without  seeking  
advice  from  the  vehicle or tire  manufacturer  or  an  authorized  Pirelli  
dealer  since  unapproved tires  on  your  vehicle  could  adversely affect  
steering,  handling,  braking  and  traction.  The  tire  information  (tire  
size, load index and speed symbol) as found on the vehicle placard or  
in  the  owner’s  manual  should  always  be  followed  when  replacing  
tires.
It is strongly recommended that Pirelli tires be mounted in sets of four  
w i
th the same tread type. Pirelli tires should not be mixed with other  
tire brands. It is  necessary to  follow this procedure because different  
tire constructions have different handling characteristics. Tires on the  
same axle must be the same manufacturer, brand, tire size, load index,  
speed rating and Pirelli part number.
When changing only two tires on a vehicle which is homogeneously fitted  
(f
 our  tires  of  the  same  tire  size),  fit  the  new  tires  on  the  rear  axle.  This  
applies to all vehicles regardless of their drive axle. (Front or Rear Drive).
On all wheel drive or four wheel drive vehicles the tires must always  
be
  replaced in sets of four.
When replacing tires on light truck vehicles, you should always follow  
th
 e  vehicle  manufacturer’s  recommendations.  Passenger  and  light  
truck  tires  are  not  interchangeable,  due  to  differences  in  their  
pressures and load carrying capacity.
P-Metric  and  Euro-metric  Interchangeability:  Euro-metric  (Example:  
22
 5/45R17)  tires  have  a  load  index  which  is  equal  to  or  greater  than  
that of the same size P-metric (Example: P225/45R17) tire. Therefore,  
they have the same or higher load carrying capacity at the maximum  
rated inflation pressure. Always check with your tire dealer or Pirelli  
Tire  Consumer  Affairs  to  be  sure  of  the  exact  interchangeability  to  
maintain proper vehicle dynamics.
Please  be aware that  it is important  that,  before fitting the suggested  
ti
 res,  the  fitment  is  allowed  by  the  technical  specifications  of  the  
vehicle,  the  vehicle  manufacturer  and  the  relevant  homologations.  
Pirelli  Tire  does  not  express  any  view  as  to  the  compatibility  of  the  
wheel/tire  combination  with  the  technical  specifications  for  the  
chassis and vehicle.
