What are hub-centric rings for?
Most aftermarket wheels have a large center hub diameter so the wheels will fit a variety of different vehicles. The hub-centric rings are made to fill the gap between the wheel and the hub of the vehicle to ensure the wheel is perfectly centered. This not only makes the installation of your new wheels much easier but will also help eliminate any vibrations you may encounter.
How do I know which hub ring to choose?
Hub rings are sized by using two different numbers that are measured in millimeters. The first number such as 108 is the diameter of the center bore on the wheel and is the outside diameter of the hub ring. The second number such as 78.1 is the diameter of the hub on your vehicle and is the inside diameter of the hub ring.
What’s better, Aluminum or Nylon?
Both have their advantages. Nylon material is inexpensive, offers high tensile strength, chemical resistance, stiffness and extreme temperature tolerance along with low thermal expansion. It will not rust or corrode, and is the material of choice for many components in your engine compartment. Nylon also has a low friction property that helps with longevity and won’t rattle or squeak. Machined aluminum hub-centric rings are extremely strong, and won’t rust. They are ideal for those who participate in autocross, track days or tinker with their cars for more than the occasional maintenance and tire rotation. When removing frequently, plastic rings can get dropped, stepped on, etc. and are prone to breaking while aluminum hub rings are virtually indestructable.
Each package contains four (4) hub-centric rings in retail packaging.
