Our 18″ cover fits

An 18 inch (457 mm) wheel is at the snug end of our cover's range: it fits 44–46 cm (about 17.3″–18″). Expect a tight stretch. Two people make it easier.

The Peterbilt 389 shipped with 18" and larger wheels depending on the build, so measure yours first.

How to measure the wheel on a Peterbilt 579

  1. Turn the wheel so the spokes sit level, and measure the rim from 9 o'clock to 3 o'clock, not across the spokes.
  2. Peterbilt's published 18 inch figure is for the standard wheel. If you have the premium leather wheel or an aftermarket one, measure it.
  3. Measure straight across the wheel, outside edge to outside edge. If it reads 44–46 cm (about 17.3"–18"), it fits. At 46 cm it is a tight fit, so two people make it easier.
