Low-Profile Tires
If the vehicle has P235/45R18 size tires, they are classified as low-profile tires.
Notice: Low-profile tires 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 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.
