GM Service Manual Online
For 1990-2009 cars only

For cold weather driving conditions you may prefer to get tires designed for snow or ice, if your vehicle has P255/50R20 size tires. See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires.

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, load range, and speed rating as your original equipment tires.

Winter tires with the same speed rating as your original equipment tires may not be available for H, V, W, Y and ZR speed rated tires. If you choose winter tires with a lower speed rating, never exceed the tire's maximum speed capability.
