Notice: If the 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. The 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. Tire Sidewall Labeling Useful information about a tire is molded into the sidewall. The following illustrations are examples of a typical P‐Metric and a LT‐Metric tire sidewall.

See the "Tire Size" illustration later in this section for more detail. 6-65
