Disregarding any of the safety precautions and instructions contained in this information sheet may result in tire failure or explosion causing serious personal injury or death.

Important Safety Warning

For your safety and protection against serious injury or death, the following safety precaution and maintenance instruction must be observed at all times.


Important Safety Check Lists

- Check tire air pressure periodically.
- Inspect tire for uneven treadwear, cracks, bulges or any sign of foreign material or trauma.
- Remember & check your tire load carrying capacity and speed ratings.
- Check your tire life. Tires must be replaced when tread is worn down to 2/32”.
- Never overload your vehicle, check tire load carrying capacity indicated on the tire or vehicle owner’s manual for the maximum   recommended load.


Tire Damage

Inspect your tires frequently for uneven wear, scrapes, bulges, separations, cuts, snags and other damage from road hazards. Damage from impact can occur to the inner part of your tire without being visible to the outside. If you have any doubt that your tire may have been damaged from hitting a pothole, curb or debris on the road, tires must be removed from the wheel and inspected for damage by a qualified person such as Hankook authorized dealer. Uneven wear can lead to internal damage or separation.


Tire Load

The load carrying capacity of the replacement tire must always equal or exceed the load carrying capacity of the original equipment tire. Tires that are loaded in excess of allowable maximum will build up heat to cause sudden destruction of tire.


Speed

When replacing tires, consult the placard or the owner’s manual for correct size and speed rating. The speed rating of the replacement tires must be equal to or greater than the speed rating of the tire being replaced to maintain the speed capability of the vehicle. Speed ratings do not imply that the vehicle can be safely driven at the maximum speeds for which tire is rated. Serious injury or death may take place if you drive your vehicle in an unsafe or unlawful manner. Hankook's speed symbol designations are verified to be in compliance with regulatory indoor test in accordance with ECE-R30,54 test. (Economic council for Europe : Procedure Load / Speed performance test for tires). These symbols are not applicable to the repaired tires.

Tire Repair

Tire mounting and inflation can be dangerous and shall be done only by specially trained persons using proper tools and procedures. Always refer to the Rubber Manufacturers Association mounting procedure and have your dealer mount your tires on rims. Serious physical injury or death may result from explosion of tire / rim assembly due to improper mounting. A tire bead diameter must always match the diameter of the rim on which it is being mounted. When inflating /dismounting RV tires, approved OSHA safety cases must be used. Never stand, lean or reach over the assembly while inflating tires.

Service Assistance /Customer Satisfaction

Make sure any repair shall be done by a specially trained person who knows proper repair and inspection procedure. Never repair tires worn below the treadwear indicators (2/32nds of an inch of tread remaining depth). Punctures through the tread can be repaired if they are not too large, but punctures to the sidewall should not be repaired at any time. Tire’s internal structural damage may occur during the service, even if a tire was properly repaired. Even properly repaired tires often have to be removed from service because the repaired damage later develops into a more extensive damage.
