Where wheels have been altered, Howmet Wheel Systems may not be able to certify the accuracy or validity of the Department of Transportation (DOT) markings that are stamped on the wheel at the time of manufacture. Alterations can also lead to cracks, bending, shrinkage, breakage, out of roundness, balancing issues, and other problems that can lead to catastrophic wheel failure, wheel separation, tire failure and/or tire separation, all which can cause serious injury or death.
Therefore, Howmet Wheel Systems does not approve of any alterations to its wheels and any such action will void the limited warranty.
