6 Ways To Avoid Voiding Your Alcoa® Wheels Warranty

6 Ways To Avoid Voiding Your Alcoa® Wheels Warranty

WARNING: Welding, brazing, or otherwise heating any area of an Alcoa® aluminium wheel will weaken the wheel. Weakened or damaged wheels can lead to an explosive separation of tires and wheels or wheel failure on the vehicle. Explosive separations of tyres and wheels or wheel failure on the vehicle could cause serious injuries or death. Never attempt to weld, braze, or heat any surface of an Alcoa® aluminium wheel.

Did you know that even something as seemingly harmless as chroming your Alcoa® Wheels instantly voids the 5 year warranty?

Alterations to a wheel may change stress points, strength, and corrosion properties in such a way that the wheel no longer meets design criteria, resulting in non-compliance with safety standards and vehicle certification requirements.

All Alcoa® Wheels come with a 5 year Warranty and are designed, manufactured, and rigorously evaluated in a tightly controlled environment to ensure they pass performance criteria only for approved applications, so it’s important to only use them for the applications they’re designed for and not to alter them in any way.

Howmet Wheels Systems Australia (distributor of Alcoa® Wheels) will not be able to consider a wheel valid for reparation under the warranty if a customer brings a wheel in with any of the below alterations:

  1. Machining (of any type)
  2. Redesigning the hand holes
  3. Reconfiguring the bolt holes in any way
  4. Welding on any part of the wheel
  5. Painting the wheel
  6. Chrome plating the wheel

In fact, the warranty conditions state, “Howmet is not liable for, does not warrant, and will not repair or replace or make adjustment, with respect to any Wheel or surface or rim flange treatment on such Wheel that has been subjected to misuse, abuse, or improper modification.”

Under Australian law, while Alcoa Wheels owners are offered extra protection from guarantees that fall under the Australian Consumer Law, these consumer guarantees do not apply if the customer has misused a product in any way that caused the problem they are seeking to be remedied.


Where wheels have been altered, Howmet Wheel Systems may not be able to certify the accuracy or validity of the certification 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, tyre failure and/or tyre separation, all which can cause  serious injury or death.
