Tire/Tire Installation and Service Life

It is recommended that the useful life of the tire be up to ten years from the date of manufacture, which may be shortened depending on the conditions of use.

Tire Uses and Precautions

1. Tires are essential components of machines or vehicles, providing forward, steering, and braking functions while reducing vibrations from uneven road surfaces.

2. For optimal performance and safety, always use tires from the same manufacturer, with matching specifications and tread patterns, suitable for the vehicle's conditions of use.

3. When mounting tires, follow the standards set for the specific rims to ensure proper fit and alignment.

4. Maintain the recommended tire pressure as specified by the vehicle manufacturer, considering the load being carried.

5. When changing tires, check the valves for leaks and ensure the valve cap is securely tightened to prevent air loss.

6. Regularly inspect tire pressure, tread, and sidewalls for damage before each ride. If any abnormalities are detected, visit a nearby automotive workshop for inspection and maintenance.

7. After mounting the wheels, carefully inspect the tire and rim for proper fit and perform a water test to check for air leaks.

8. Tires that have been in use for over 5 years should undergo a thorough inspection to determine if they are safe to continue using.

Storage Considerations: Avoid the following situations in the storage area:

1. Avoid storing in areas directly exposed to sunlight and rainwater infiltration to prevent rapid aging of tires/tubes.

2. Avoid storing in high-temperature areas near heat sources, sparks, or open flames to prevent rapid aging of tires/tubes and to prevent them from becoming flammable materials in case of fire.

3. Avoid contamination with oils and chemicals to prevent deterioration of tires/tubes.

※evaluation by professional staff: repair or replace※

Usage Limits: It is recommended to immediately replace the tires/tubes in the following situations:

1. When the remaining tread depth is less than 1 mm and there are three or more wear indicators around the circumference of the tire/tube (indicated by ▲), indicating that the remaining tread depth is less than 1 mm. The tire/tube should be replaced immediately when the wear indicator aligns with the tire/tube surface.

2. When there are deformations or bulges in the tread or sides of the tire/tube.

3. When there is external damage and a professional determines that it cannot be repaired.

4. It is suggested that the lifespan of tires/tubes be up to ten years from the date of manufacture.

※The lifespan of tires/tubes may be shortened based on actual usage conditions.

Tire Repair

1. DURO does not endorse or approve the repair of any of its motorcycle tires that have suffered punctures or other damages. DURO assumes no responsibility for injuries or consequential damages resulting from DURO tires that have been patched, plugged, sealed, or repaired in any other way by a distributor or consumer.

2. Refer to instructions #6 and #8 in this brochure for detailed information on the use and precautions of the tires.



1. Ensure that the tire(s) have a sufficient load-carrying capacity for your vehicle and any additional weight. When calculating the load capacity, consider the weight of the motorcycle, the weight of any luggage or additional accessories, and whether you are carrying passengers. Proper tire inflation is necessary when making this calculation. Never exceed the vehicle load capacity specified in your motorcycle owner's manual or the maximum load indicated on the sidewall of your tires.

2. Never use your motorcycle with underinflated tires. This can lead to improper handling that may result in an accident. The only way to determine if a tire is properly inflated is to check air pressures with a precise tire pressure gauge when the tires are cold (at ambient air temperature).

3. Underinflation can also allow a tire to rotate on the wheel. In a tube-type assembly, this can cause the valve stem to be pulled from the tube, resulting in rapid deflation. It may lead to the loss of control of the motorcycle, causing potential damage, injuries, or both. By not fully tightening the valve nut to the base of the rim, you allow the valve to tilt freely in the event of tire rotation on the rim. This will provide a warning so that the cause of this irregularity can be determined and corrected.

4. Refer to this brochure for information on part that says the usage & precautions, and usage limits of the tires.

5. Do not mix bias ply and radial tires on the same motorcycle.

6. Do not use a tube type tire without a tube in a tubeless rim.



DURO has specific recommended conditions for the storage, selection, assembly, inflation, pressure, use, monitoring, and maintenance of its tires. The conditions established by DURO must be followed by the customer. The customer is obligated to inform users and their own customers about these conditions.
