218 Car care
Rotating the tires
Because of front wheel drive, the front tires
tend to wear faster than the rear ones. New
tires should always be fitted in pairs, so that
tires on the same axle have the same
amount of tread.
If swapping the complete set, e.g. winter
tires for summer tires, mark the tires
removed to ensure that they go back in the
same position (e.g. FL for front left, RL rear
left, etc.).
Store wheels lying flat or hanging – never
standing upright.
Tire markings
An example of the meaning of the different
markings in a tire size is given below for a
tire size of 195/60 R15 88V:
Winter tires
Winter (snow) tires are recommended for
winter climates where the majority of your
driving will be done on snow and ice. Winter
tires should be fitted to all four wheels to
maintain a proper balance. Your Saab
dealer can advise you of to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires pre-mounted on steel or alloy rims.
Tire quality grading (cars sold in
U.S.)
New tires must be graded and labeled in
accordance with new Federal regulations.
Standard tests are conducted to measure
performance in the areas of traction and
temperature resistance. Refer to the tire
sidewall for the specific quality grades of the
tires provided on your new Saab. Compact
spare tires are exempt.
DOT QUALITY GRADES
• Treadwear.
• Traction AA, A, B, C.
• Temperature A, B, C.
All passenger car tires must conform to Fed-
eral safety requirements in addition to these
grades.
WARNING
When fitting just one new pair of tires,
these should be fitted to the rear wheels,
as these are more critical to the direc-
tional stability of the car (e.g. on braking
or in a skid). The existing rear tires should
therefore be moved to the front. Always
move left rear to left front and right rear to
right front, so that the direction of rotation
remains the same.
