This is why I will only buy JWL certified wheels.

This is in the Pic's section, but thought it should be posted here.
There was a thread here recently about how many wheels are not certified by anyone. Just wanted to show that wheels do break for no reason.
Who knows if it's really forged, but it also shows just because a wheel is "forged" it doesn't mean it's strong.

Yup. It's amazing how many people are willing to drive their car on non-certified wheels. Here's a great video from Weds that shows a bit of what JWL certification requires. Just because a wheel is forged, doesn't mean it has been designed with durability and strength in mind.

so which companies are certified?

^^^ excellent question

APEX, Volk, Advan.. etc.. etc..

and...not ADV.1

i stay with HRE / Volk / Advan / BBS for my past 15 yrs of my car.

Not sure if HRE wheels are JWL, but they've been around for a while. It's all these new companies that I really worry about.

^ HRE has received TUV quality they are definitely a reputable wheel manufacturer: http://www.hrewheels.com/blog/hre-receives-tuv-quality-verification-status/. TUV is a german equivalent to the japanese JWL.

HRE had some issues when they first came out. They were banned from many racing/tracking venues. Their philosophy in building wheels has drastically changed since then. One thing to make a mistake, another to man up and fix it. Would not hesitate to buy their wheels.

HRE, BBS, Volk, Advan, Apex would be wise choices.

Not a true story and not the first time the issue has come up here. This link has comments from HRE: http://www.m3post.com/forums/showpost.php?p=4814883&postcount=16. There is some additional info in the full linked thread.

I'll go into great detail in a special thread on the subject later for now I'll just touch a few basic points:

JWL is a self "certified" test that is close to meaningless on it's own due to shady industry practices. It's performed in-house by the manufacturer, and it's cheated in numerous ways due to zero regulation. There is no master list as it's self certified, so you can't verify what is real and what is not. It's easy to fake (companies stamp many of the logos onto anything), and I could name many wheels that do not even conform to this basic test even though they claim they do.

JWL for that reason is no where near as important as true VIA and TUV certification. This testing cannot be performed in-house to receive an official certificate for a wheel. It has to be sent out them for independent testing. Manufacturers again lie about this process, simply because their in-house testing equipment has been certified to have the ability to recreate those testing standards. That by itself is again meaningless. That's like saying you take practice SAT tests in the same format the real test is given (no college would accept the self test).

To have a wheel certified by JWL or TUV, you first need your own equipment certified, and perform your own in-house testing using their standard. This means each wheel has to be crush tested multiple times in-house (not FEA). After in-house testing is done a sample is sent to the VIA or TUV for official testing by them (3rd party). If you do not send them a sample, then that wheel cannot be certified. They must have a real wheel and tire shipped to them to verify the results of the in-house testing. Once a wheel is certified it will be listed on an online registry database.

This is why I am more concerned about those that lie about VIA/TUV certification. It would be like making the claim that a car received a 5 star crash safety rating, when in fact the NHTSA never even touched the car.

Thanks Eddy.

I thought JWL was the one you had to ship the wheel in for torture testing, and VIA was a self certification?
During the RAC group buy, we had to wait a while for the testing to be done since it was during a holiday, or something like that.

JWL can be done in-house, VIA however can be certified by sending the actual wheel to them.

JWL is the testing standard. it dictates the testing loads based on the wheel diameter and bolt pattern.

VIA is not a test. It is a testing organization. They test to the JWL standard. to be only JWL means a wheel was self tested. to be VIA means a wheel was officially tested by the VIA in Japan following the JWL testing method.

A Wheel that passes JWL does not make it VIA certified, even if it's stamped onto the wheel (what many companies do)

Read my post. That's what I said. JWL is a testing standard. VIA is a certification done by a testing council.

Not the first time I hear of this...here is some background on this great company:

When the original 360 Forged started going through all their problems Rennen started to sell counterfit 360 Forged wheels at a huge discount. Great right?

Well now 360 Forged has been getting calls from customers saying their 360's cracked and they want them repaired. Problem is 360 never built those wheels but they are basically forced to fix them because the customers can't understand they got scammed by Rennen.

Want more...every cracked wheel is this five spoke split design!

Your post was not clear. I am simply clarifying/adding to your statement. It was not a personal attack.

No harm in clarification. Everyone's on the forum to gain information.

All of our wheels are load tested and certified. Email me if you would like scanned documents of proof.

We are TUV certified as well.
