AIRODISC / Sizes
We stock 18, 19, 20 inch. There is no 17.
Order by the wheel, never the disc. A disc runs about two inches larger than the wheel it covers. A 20 inch wheel takes a disc of roughly 21.97 inches, so anyone ordering by the disc's own measurement ends up one size too big.
Counts are of the cars we publish fitment for, not of every car that exists in that size. 19 inch is the busiest by a distance.

Spread widely across the range, from Audi through to Hyundai / Kia / Genesis. A mainstream size, which means the bolt pattern matters more than the diameter here.

An AIRODISC does not sit inside the rim the way a factory hubcap does. It mounts through a spacer to the wheel's own bolt pattern and covers the face from outside, so it has to clear the rim lip rather than tuck behind it. That is where the extra two inches go, and it is also why one disc can fit wheels it was never designed around: the mount is the bolt pattern, not the rim profile.
The practical consequence is the sentence at the top of this page. Measure or read your wheel size, the number stamped on the tyre or quoted on the wheel, and order that. If you measure the disc on a car that already has one and order to that figure, you will be one size out.
We publish 77 confirmed cars across 5x112, 5x114.3, 5x120. If yours is not among them the mount is not make-specific, so order with the car and wheel noted, and we check it by hand before anything is cut, with a full refund if it will not fit.
