MSI Wheel Blanks

Wheel Blanks


Our wheels are manufactured in the USA. They start from a solid bar of 6061-T6 aluminum. All our wheels are one-piece wheels. They are rotary forged and machined to meet the requirements by the Tire and Rim Association. Not only are these wheels inspected by the manufacturer themselves, we have our Quality Inspectors looking over the wheels too. We also offer polishing services for all of our wheel blanks.

Did you ever wonder who really invented the wheel? It wasn’t the caveman. The Mesopotamian civilization is credited with the invention of the first wheel. Although there is no one person that can be applauded for inventing the wheel since they started showing up throughout Western Asia. This historical region includes the present-day Iraq, Kuwait, Iran, Syria and Turkey. We have come a long way from the early wheels that were simple wooden disks with a hole for the axle.
