Wheel care guide
Wheel checklist
Make sure that the wheel size, inset, number of mounting holes, P.C.D., mounting surface shape, etc. are compatible with the vehicle to be installed.
If these are incompatible, it cannot be installed in the car.
Install wheels of the same size and type on each axle.
Mixing different wheels may result in loss of maneuverability and stability.
Tire and wheel damage can occur if wheel and tire sizes do not match.
Installation of valve stems
Please use the included dedicated valve stem.
Tighten the nuts of clamp-in (nut tightening) type valves to the torque specified by the manufacturer.
When installing the tire, replace the valve with a new dedicated valve.
If the old valve is used as it is, air may leak due to deterioration of the rubber such as the grommet (rubber packing for the air seal).
Installing the center cap
Center caps and center plates have various mounting mechanisms depending on the model. Please install the special type according to its instructions. Please handle the installation and removal of the center cap carefully. Hitting or other impact may damage it.
Please handle carefully when installing and removing the center plate while the wheel is attached to the vehicle. Damage due to dropping or damage to the wheel itself may occur.
Mounting the lug nuts
Selection of mounting nuts and bolts
Wheel mounting nut seats (bolt seats) include 60-degree tapered seats, spherical seats, and flat seats. Please use nuts (bolts) that match each shape. Make sure that the hub bolt (bolt hole) of the vehicle matches the diameter, thread pitch, and length of the nut (bolt) to be installed.
Wheel care and cleaning
Aluminum wheels are highly resistant to corrosion, but they are vulnerable to anti-freezing agents and salt. Wipe off completely.
The use of sponges and polishing with some compounds may also cause scratches.

Some commercially available wheel cleaners (cleaning liquids) and body cleaners contain ingredients that cause discoloration, stains, and unevenness (those with strong acidity or alkalinity, or those containing abrasives). Please read it carefully before using it.

Washing your car in a car wash can damage your wheels. Manual cleaning is recommended.
When storing wheels, clean and dry them thoroughly and store them away from direct sunlight, rain, water, oils, and places with high temperature and humidity. In the case of long-term storage, record the position where it was installed, and lower the tire pressure to about 1/2 that of when you use it. When using the product again, replenish the air pressure in the tires, check the air pressure, adjust the balance, confirm that there are no abnormalities in the tires and wheels, and pay attention to the mounting position.
