All of our wheels go through a detailed testing process. These tests consist of load, corrosion, temperature, and destruction testing. We make sure that our wheels are not only strong enough to handle normal daily driving, but high stress situations as well such as racing, off road conditions, rough road conditions, and more. Due to these stringent tests, we have the utmost confidence in our wheels.
Testing procedures and certifications:
- Fatigue and Dynamic Durability testing specified by DOT 109.119 and 139.
- High speed Durability testing (up to 230mph)
- Rolling resistance testing Passenger. Medium Truck Spindle Force Method per SAE J-1269
- Coast-down rolling resistance testing per SAE J-2452
- X-ray and Shearography non-destructive analysis
- Bead Unseat and Plunger Energy per SAE J-916c and DOT 109,119 and 139
- Dynamic Impact testing with cleated roadwheel.
- Wheel impact test by SAE. ISO and JASO methods. Force and velocity requirements to GM requirements.
- Strain Gaging
- Salt/Add spray - Salt spray ASTM B117 method and GM WL15-5-81 stress corrosion test CASS acid test ASTM 36a
- Hydroburst Testing -Strength studies for wheels.
AJI of our finishes are corrosion tested. We use several methods of corrosion testing. One of the most damaging elements a wheel can endure is salt. We put all of our finishes through a 1000 hour non stop direct spray of salt water. Granted, we can't design a wheel that is 100% resistant to these conditions, however with proper care, and maintenance such as regular cleaning, our wheels are able to endure years of abuse from the elements. Through this test, only minor damage is seen on the wheels dear coat finish, which can be re-coated, and polished to bring back it's original luster.
Extreme Temperature Testing:
During extreme situations such as racing. our wheels are often times heated to very extreme temperatures. We test to ensure that structural integrity of the wheel remains intact during and after these conditions. and that no fatigue is endured. Our wheels are also tested in extreme cold conditions where metal can become brittle. The results of our tests conclude that our wheels are able to withstand the most extreme temperatures, hot or cold.confidence in our wheels.
Forged Distributing wheels are made to withstand extremely high load situations. We not only design our wheels to withstand the vehicles weight, but the centrifical force as well. If a vehicle weighs 3000 pounds and is able to pull 1g of lateral acceleration through a turn, we ensure our wheels can handle the stress of excess of 3000 pounds puling the wheel in either direction as well as the force pushing down on them. We've designed our wheels to handle loads far beyond what normal driving situations would submit them to.
Every wheel has it's breaking point. and it's weak point We determine where the wheels weak point is. and stress test it to the point of failure. The one thing that we are trying to accomplish during this test is that you never see this point. With that bong said, we design our wheels to far exceed the maximum stress levels caused by normal driving and even racing conditions. During normal conditions, the usual damage is done by hitting a pothole. which normally results in a bent inner or outer rim half. These situations are often times unavoidable. Being that our wheels are a 3 piece design, we can un-assemble them, and repair or replace the individual piece, or pieces that are damaged rather than replacing an entire wheel.
