How is Replacement Trailer Wheel Center Cap Picked Out

Published 10/12/2023

Question:

How do I measure for a chrome hub cover? the OD of my cap is 3.675 but that does not seem to exist on most websites. 15 alloy wheels on a 2016 Jayco. Am I measuring wrong?

To determine which trailer wheel center cap you'd need you'd need to measure the diameter of the center hole that your current wheel has like you've basically done by measuring outer diameter of your current cap. Most 15 inch trailer wheels have a pilot diameter of either 3.19 inch or 4.25 inch so it is interesting that yours is a non-standard size that we don't carry.

I attached a link to a page that has all of the center caps we carry and you can select your pilot diameter from on the filters of the page.
