Low-Profile Performance Tire If your vehicle has P225/50R18 or P225/50R17 size tires, they are classified as low-profile performance tires. These tires are designed for very responsive driving on wet or dry pavement. You may also notice more road noise with low-profile performance tires and that they tend to wear faster. Notice: If your vehicle has low-profile tires, they are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like, potholes, or sharp edged objects, or when sliding into a curb. Your vehicle warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and, when possible avoid contact with curbs, potholes, and other road hazards. If you expect to drive on snow or ice covered roads often, you may want to get winter tires for your vehicle. The low-profile performance tires may not offer the traction you would like or the same level of performance as winter tires on snow or ice covered roads. Winter tires, in general, are designed for increased traction on snow and ice covered roads. With winter tires, there may be decreased dry road traction, increased road noise and shorter tire tread life. After switching to winter tires, be alert for changes in vehicle handling and braking. See your retailer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires on page 5-79. 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 and ZR speed rated tires. If you choose winter tires with a lower speed rating, never exceed the tire's maximum speed capability.
