Default ADR rims not DOT approved - what does this mean?

I did a few searches and the general consensus is that ADR stands for Another Destroyed Rim =(

Someone also said they are not DOT approved.

What does this mean? A standard of some kind, but what does it test?

I'm asking because I went in to the local performance shop to get quotes on some wheels and he showed me some ADR wheels that look like the Work Emotions.

Looked pretty good but I remembered how many people said ADRs sucked.

Thanks!

DOT = Department Of Transportation

To earn DOT approval, the manufacturer has to prove that the rims can handle the forces a rim is expected to withstand.

As far as I know, all of the ADR rims are cast, not forged.
As a rule, cast wheels are not a strong as those that have been forged.

Personally, I have never heard about an ADR rim failing in a catastrophic way... but I can imagine some pretty awful ways...like disintegrating while cornering at 10/10ths.

Since the DOT has not approved the rims for use on public roads, they probably aren't your best choice. I'd save up for a set of stronger wheels from a better manufacturer.

Cool. Thanks for the explanation. As of now I doubt I can afford forged rims, but I'd like something to run on for the summer other than the blades. (I bought my car with winter tires mounted on the blades).

I've been seriously looking at Konig. Are they DOT approved? I know they are cast also, but it seems like other cast wheels hold up better than ADR.

I've heard of some ADR rims...and seen pictures of...some ADR rims that have the spokes break off of the hub during normal driving. That kind of failure is pretty catastrophic.

Alrite looks like I'll be staying away from ADR.
What other kinds of damage is taken by the car if that even happens to your wheels?

Suspension? Axles?

Jesus...it would be horrible.
If a wheel were to fail at speed, it could lead to a crash that writes off the whole car.
