Safety Instructions:

  • Please adhere to the standard or optional tires specified by the automobile manufacturer. If you are considering selecting alternative tires, kindly consult with tire dealers. 

  • Agricultural machinery tires vary in size and tread pattern based on the type of machinery (small tractors, large tractors, cultivators, etc.) and their placement (front or rear wheels). Therefore, when using them, please consult tire dealers. 

  • WARNING: Please do not use tires of different sizes, types, structures, or designs on the same axle, as it could lead to varying tire performance and potentially result in accidents.

  • WARNING: Do not use tires that have been regrooved, punctured, or subjected to any modifications, as they may be damaged and pose a risk of accidents. 

  • WARNING: For wheel selection, please consult tire dealers or similar experts and use wheels that are suitable for the tire size and vehicle. Additionally, note that some wheels fitted on imported machinery might not match the tires. Please ensure proper compatibility before installation. 

  • WARNING: Regularly check the tire pressure using an air gauge when the tires are cold. Inspect them at least once a month and ensure they are adjusted to the tire manufacturer's recommended pressure. Avoid both over-inflation and under-inflation, as improper tire pressure can lead to damage and increase the risk of accidents. 

  • WARNING: Please inspect the tires for cracks, and check if there are any nails, metal fragments, glass, or other objects stuck in them. Also, ensure that there are no foreign materials lodged in the grooves. If you discover any foreign objects, consult with tire dealers or similar experts before removing them. 

  • DANGER! Do not use tires with external damage that reaches the internal cords (fibers, steel cords) or has rubber cracks. Damaged tires can lead to accidents. For guidance on whether repair is possible, consult tire dealers or similar experts. 

  • WARNING: Worn-out tires exhibit reduced performance, including decreased handling capabilities and increased susceptibility to slipping on soft or wet road surfaces. Please replace them with new tires for optimal performance. 

  • Please ensure that there is no loosening or detachment of wheel nuts, and check for abnormalities such as breakage or deformation of wheel bolts. 

  • WARNING: Please do not exceed the specified vehicle load capacity or passenger capacity, as it could lead to tire damage. 

  • If the tire has specifications such as rotation direction or mounting method indicated on the sidewall, please ensure to correctly install it according to those specifications. 

  • To ensure safe driving, during tire inspection, please also check the condition of the valve stem for deterioration or cracks. If there is any deterioration or cracks in the valve stem, please consult tire dealers or similar experts. Additionally, ensure that the valve caps are in place. 

  • WARNING: Please inspect the wheels for any damage such as cracks, deformations, or significant corrosion. Also, ensure that wheels that have been welded or modified are not used. Leaks in tire air can lead to damage to the tire and should be avoided. 

  • Please refrain from using instant puncture repair kits or tire shine products that could have harmful effects or cause degradation on the tires. 

  • WARNING: To prevent potential damage to the tires and wheels, avoid making contact between the sidewalls of the tires and road curbs, and also avoid driving over road depressions or obstacles on the road. 

  • WARNING: Sudden starts, rapid acceleration, abrupt turns, and abrupt stops are dangerous, so please avoid them. Especially on wet surfaces, slopes, and snowy roads, which can be slippery and increase the risk of accidents, exercise appropriate driving practices such as reducing speed on sharp curves according to the usage conditions. 

  • WARNING: If your vehicle becomes unstable during driving or if you experience abnormal noises or vibrations, promptly pull over to a safe location and inspect both the vehicle and the tires. Even if there are no visible abnormalities, proceed at a low speed if possible and request an inspection from a tire dealership. 

  • WARNING: Adjust the air compressor valve according to the correct pressure for the tires, based on the following table. Please note that water from the compressor might enter the tires, so perform regular drainage as well. 

Tire Recommended Air Pressure Categories

Maximum Adjustment Pressure for Valve

~400kPa (4.0kgf/㎠)

500kPa (5.0kgf/㎠)

400kPa (4.0kgf/㎠) ~600kPa (6.0kgf/㎠)

700kPa (7.0kgf/㎠)

600kPa (6.0kgf/㎠) ~900kPa (9.0kgf/㎠)

1,000kPa (10.0kgf/㎠)

900kPa (9.0kgf/㎠) ~1,200kPa (12.0kgf/㎠)

1,300kPa (13.0kgf/㎠)

  •  DANGER To avoid the risk of explosion, please take safety precautions such as placing the tire within a safety enclosure before inflating it with air. 

  •  DANGER If you hear any unusual sound from the tire sidewall area while inflating or after inflating, immediately cease the operation and evacuate for safety. 

  • WARNING: The bead seating pressure during tire rim assembly is indicated on the tire. Do not exceed this pressure during inflation. (Bead seating refers to the state in which both sides of the tire's bead are evenly seated on the rim's bead seat during tire assembly). 

  • After inflating with air below the bead seating pressure, ensure that both sides of the tire's bead are evenly seated on the rim's seat area. Then proceed to inflate the tire to the recommended air pressure. 

  • WARNING: After inflating the tire, before attaching the valve cap, make sure there is no air leakage from the valve core or around the rim and valve area. Once confirmed, securely attach the valve cap and tighten it. 

  • Foreign objects or moisture inside the tire can compromise its functionality. Before rim assembly, inspect the inside of the tire and remove any foreign objects or moisture.

  • When removing the wheel, please inspect the wheel bolts, nuts, and wheel disc for any damage such as breakage, cracks, deformations, or corrosion. If any damage is found, please replace with new parts. 

  • Please use a torque wrench to tighten the wheel nuts to the specified torque. If using an impact wrench, take care with tightening time, air pressure, etc., and exercise caution to avoid over-tightening. Consider using a torque wrench for verification in conjunction. The tightening torque for the wheel bolts may vary depending on the model. Refer to the user manual for guidance. 

  • Store tires away from direct sunlight, rain, water, oil, heat sources such as stoves, and devices generating electrical sparks. 

  •  DANGER!  There is a risk of tire burst if the air pressure is too high. The proper air pressure and rim assembly precautions are indicated on the tire, so please ensure to check them. 

  • When storing tires individually, especially ensure that water and foreign substances do not enter the inner side of the tire. 

  • If tires are stored for an extended period after removal, there is a risk that chemicals from inside the tires might seep out and soil the floor. Please refrain from doing so. If you need to store them on the floor, consider using thick material like cardboard as a protective layer. 

  • When storing tire-wheel sets, store them sideways as much as possible to minimize deformation of the contact area. Additionally, adjust air pressure according to the manufacturer inflation instruction (table). 

  • If rim assembly is not done properly, slippage can occur between the rim and tire, leading to tire damage. Especially in the case of two-piece rims, ensure that there is no gap between the upper and lower rims by tightening the bolts appropriately. 

  • For lug-pattern agricultural machinery tires, there is a designated rotation direction indicated by an arrow on the tire's sidewall. This rotation direction is intended to enhance mud shedding, flotation, and traction effects. Please take extra care when installing, ensuring the proper rotation direction. 

  • During and after driving, the air pressure may increase due to heat. However, please refrain from releasing the air pressure. 

  • To ensure optimal tire performance, it is important to use the appropriate air pressure. Using improper air pressure can lead to reduced work efficiency and tire damage.
