Warning, vehicle models that cannot be installed
● Vehicles with numbers 1, 4, and 8
● Drum brake vehicles with uneven mounting surfaces
● For special vehicles other than the above, please contact us.


Precautions when installing the wide tread spacer
* Please do not install other than domestic cars.
● If the tires and wheels are subjected to a strong impact, excessive force will be applied to the wide tread spacer, and if it is used as it is, it may be damaged and may lead to an accident. Therefore, never use the product. ..
● Depending on the thickness of the spacer and the offset of the wheel, it may not be possible to install it on the vehicle (protruding from the fender or contacting the tire house)
. When purchasing, please check the condition of the current car before purchasing.
● Do not mount steel wheels as the mounting surface is not flat.
● Before mounting, be sure to remove rust, dirt, etc. from the mounting surface on the back side of the wheel and the hub side of the vehicle body with a wire brush, etc. before mounting.
● Do not apply oil or grease to the hub bolts of the car body, hub bolts of spacers, and mounting nuts. The
bolts may be damaged if tightened more than necessary .
● If there are foreign objects or protrusions on the hub side of the car body or the back side of the wheel, do not install it.
● When the wide tread spacer is attached to the vehicle body hub bolt, if the bolt protrudes from the spacer,
do not attach the wide tread spacer .
● If there is an “escape” on the back side of the mounting wheel, it is possible to mount a wide tread spacer. However, if the “escape” depth
is not enough to allow the genuine stud bolt to escape, do not install the wide tread spacer.
● Drum brakes whose mounting surface is not flat Cannot be mounted on vehicles or if there are protrusions. Also,
never install it on a vehicle with steel wheels .
● Some vehicles have a large hub diameter, and wide tread spacers may not be installed.
When purchasing, please check the diameter of the vehicle hub and the inner diameter of the wide tread spacer before purchasing.
● After installing the wide tread spacer, it is recommended to adjust the alignment to prevent uneven wear of the tire.
● When installing on a vehicle with a sliding door, be careful not to let the tires stick out. The sliding door may
interfere with the tires and prevent it from opening.

Please note that the 10mm hub-centric ring may not be installed on vehicles with a vehicle hub height of 12mm or more, depending on the shape of the wheel mounting surface .
● We do not guarantee any failure or damage due to incorrect installation or handling.
