Winter Tires
If you expect to drive on snow or ice covered roads
often, you may want to get winter tires for your vehicle.
All season tires provide good overall performance on
most surfaces but they may not offer the traction
you would like or the same level of performance as
winter tires on snow or ice covered roads. If you choose
to use winter tires:
• Use tires of the same brand and tread type on all
four wheel positions.
• Use only radial ply tires of the same size as your
original equipment tires.
See Buying New Tires on page 5-68.
Tire Sidewall Labeling
Useful information about a tire is molded into its
sidewall. The examples below show a typical passenger
car tire and a compact spare tire sidewall.
