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.
