1.The confirmation of the conformity

• Confirm whether you can attach the size of the wheel and specifications
  to the applicable car kind.The number of holes, PCD A different thing can't be attached. Stop the installation to give processing and so on absolutely because it is dangerous.
• Confirm the specifications of the wheel nut. There is classification such as teper seat, a spherical surface seat and a plane seat in the installation nut seat of the wheel. Use the nut which surely copes with a wheel. When the nut that a form is different is used, enough tightening can't be only done It causes looseness, and a wheel comes off, and it is very dangerous that it is connected with the accident. Never use.

2.Preparation for installation

• An air valve is to use a special attached valve. And, do tightening securely. Imperfect tightening becomes air omission.And, excessive tightening is the damage of the valve. The early deterioration of the sticker material is caused.
• Confirm the size of a tire to combine with the wheel. A tire has an allowable load.Therefore, of the tire of the poorer allowable load than pure proper installation goods Installation can't be done.Confirm it to the tire maker when it is unavoidable. A number after the tire size is the indication of the allowable load.

  ex.Pure proper installation 185/60-1482H →195/55-15 84V・・OK
  185/55-15 81V・・NG
  
  When it exceeds an allowable load, it is connected with the damage of the tire, the damage of the wheel, and so on, and it is very dangerous.

3.Installation

• Confirm that there is no air omission after the tire attachment.
  The fusion part of the tire and rim
• Confirm that there is no , Be especially careful around the air valve.Stop installation when there is air omission. Adjust
• Air pressure to the regulation value.The air pressure which is proper when tire size is changed Ask it to the tire maker because it sometimes changes. Adjust wheel balance with all the circles as well after the tire attachment. A balance defect doesn't only cause an unusual vibration and abrasion of the tire. It becomes fatigue promotion to the wheel and the body side, and dangerous. Fasten an installation nut by the recommendation torque when you attach it to the body side.
• As for lack of torque, looseness of the installation nut, a over-torque are the damage of the body side bolt. The deformation of the wheel nut seat side is caused, and it is dangerous.
• When the installation that spacer and so on is used spoils wheel's own strength, precision. Stop it because it is here. Thing with no contact with the part and interference in the body, the suspension, and so on in the installation to the vehicles Confirm it.

4.Chack

Keep the next strictly as an opening daily inspection.

• Be sure to check air pressure before running. The performance of the tire isn't only spoilt, and lack of air pressure is a bar strike (the explosion of the tire).
  There is danger such as A tire comes off, and a wheel is damaged even by a few shocks, and is dangerous.
• The inspection of the air pressure is carried out (When a tire and a wheel get cold.) before surely running, and it is bottom .When air pressure rises and it is adjusted at this time, it is air between temperatures right after running in the time at tire and a wheel get cold. It becomes lack of pressure.
• Check whether there are not deformation and a crack in the wheel.Together, in such cases as the center cover It is installed securely to fall during running never when there are accessories. Confirm that you are here.

  If, stop use at once when there are deformation and a crack in the wheel.

  Precaution in use of

• Impossible running such as urgent starting, urgent system movement and an urgent turn hurts a tire and a wheel in the rough operation. It is not it.Never do it because a serious accident isn't hard to cause.
• Be careful of the sidewalk and the unevenness such as hollow of the road because it sometimes becomes the cause that a wheel is transformed and a crack is brought about.
• If it feels unusual sound and so on during running, the vibration, it stops in a place to be safe at once, and it is checked. Give it to me.
• Never do over-loading.As for over-loading, a burden is only applied to the tire and the wheel.

5.daily cleaning, a maintenance

• Use under the condition which is always beautiful by washing in water and so on because the road freezing prevention medicine of the snowfall area and the salt of the seashore area cause corrosion , a maintenance, aluminum alloy are excellent metals .
• Use after you read a use manual well when you have the wheel cleaner and so on which generally is in the market used.A coating side is sometimes hurt by the case.And, be careful of long leaving of the actualities that a detergent kind stuck because a coating side may be hurt.
• Air valves are expendable supplies.A periodic exchange in every 1 is recommended.

6.Others

• Others, assembling-type isn't to add a hand to the combination bolt of the disk of the wheel and rim and the nut at all.
  Strength declines, and very dangerous when it has tightening, a resolution, and so on done.It becomes the outside of the object of all the compensation.
• It is never to do the wheel which a thing such as deformation and a crack was formed in that you give a repair by the repair dealer, the guest himself, and so on, processing, and so on.
  It is very dangerous because original strength, precision are spoilt.。
  It becomes the outside of the object of all the compensation.
• The damage of the wheel may occur because it sticks for the use of circuit running , a rally, and a burden beyond the load prescribed by "the technological standard of the light alloy disk wheel" by those use conditions is applied.Therefore, carry out the inspection of every running fully.
  Be careful because it is attached to the wheel which did circuit running and it becomes the outside of the object of the compensation.

About a standard

JWL:(JAPAN LIGHT ALLOY WHEEL):
The technical standard for Light Alloy Disc Wheels for Passenger Car
approved by Ministry of Transport (MOT)

JWL-T:(JAPAN LIGHT ALLOY WHEEL TRUCK & BUS):
The technical standard for Light Alloy Didc Wheels for Truck and Bus
approved by Ministry of Transport (MOT)

VIA :(VEHICLE INSPECTION ASSOSIATION) Registration System :
marking can only be engraved on the wheel is registered by Japan
Light Alloy Automotive Wheel Testing Council after strict quality
tests by the authorized testing facility on the adaptability ofor
technical standard.

There is the following thing in the prescribed examination.

• Dynamic cornering fatigue test
  A load in the cornering is presumed, and the strength of the disk part is
  asked to a master.It is bent concretely in the wheel, and cornering
  moment load is given, and the regular number of rotation is turned,
  and strength is confirmed.
• Dynamic radial fatigue test
  A load in the vertical direction is given to the wheel concretely by a test
  to do to ask a master the strength of rim part, and the regular number
  of rotation is turned, and strength is confirmed.
• Impact test
  A weight is made to fall into the wheel, and the whole strength
  is confirmed.
