General information
Your vehicle  is equipped  with tires according to the tire information label on the inside  of the fuel filler door.
The following is an  example  of a  tire designation code: 225/55 R16
225 =  tire width in mm.
55 =  tire profile. This is the relationship (in percent) between the section height and  width of the tire.
R =  radial tires.
16 =  diameter in inches.
The tires have good road holding characteristics and  offer  good handling on dry and  wet  surfaces. It should be  noted
however  that the tires have been developed to give these features on snow/ice-free surfaces. Certain models are
equipped  with "all-season" tires, which provide a somewhat higher degree of road holding on slippery  surfaces
than  tires without the "all-season" rating. However, for optimum road holding on icy or snow covered roads - we
recommend suitable winter tires on all four wheels . When replacing tires, be  sure that the new tires are the same
dimensions, type (radial)  and  preferably from  the same manufacturer, on all four wheels. Do not use bias ply tires.
Otherwise there is a  risk of altering the car's roadholding and  handling characteristics.
NOTE:  When storing wheel/tire assemblies (e.g. snow tires and  wheels), either stand the assemblies upright, or
suspend them off the ground. Laying wheel/tire assemblies on their sides for prolonged periods  can cause wheel and/or
tire damage.
Wear indicator
The tires have wear  indicator strips running across or parallel to the tread. When approx. 1/16" (1.6 mm) is left on the
tread, these strips become visible and  indicate that the tire should be  replaced.
