G.MAX wheels comply to the VIA, VIA/T (Trucks), JWL and TUV standards. Products that comply with international standards ensure higher quality, safety, reliability and efficiency.
 

If you are spending thousands of dollars for a new set of alloys, it wouldn't hurt to take a few minutes to look at the back of the wheel for the following markings:
 

1. Size of the wheel - They have to be the same as what they promised you.
2. Load rating - The wheel has to be correctly load-rated for your car. Sometimes advanced load-rating tests are performed under special requests and the load rating changes after the engraving has been made, remember to ask for a proper test report to prove that change.
3. Offset - It is very important that the correct offset is used. A wrong offset will result to the wheel sticking out of the fender or cause rubbing or handling problems.
   
   NOTE: Please do not accept the retailer's request to file the center of the wheel to create a larger offset as they may damage the structure of the wheel. Most manufacturers would not take any responsibility for their products if modifications are done without their consent.
4. Country of production - It is recommended that you find a wheel that is not ashamed to tell you where they are made from. Sometimes they include the name of the design house if it is an original design.
5. Quality Assurance Standards - Look for Japanese standards such as VIA, VIA/T (for SUV or 4WD), JWT or TUV behind the wheel for quality assurance.
